What battery is better for the screwdriver, the characteristics of the batteries

Drill, screwdriver - the tools necessary in everyday life. It will be useful to purchase them to everyone who is engaged in the arrangement of the house with their own hands. Also for workshops-professionals, the screwdrivers are now indispensable. And since in the building toolkit stores, they have a huge choice, many may have reasonable questions: what tool is better to choose and what battery is better for the screwdriver? From the choice of acb, it depends a lot: first of all, the mobility of the tool and the duration of its work in standalone from the network conditions. Before you finally decide which batteries are most preferable in any case, you should read more detail what batteries are used in the screwdrivers.

Types of batteries

So what are the batteries? Typically, nickel-cadmium and lithium batteries are used for the electrodes. There are also nickel-metal hydride acb, and they are good in their own way. But for the screwdrivers, they began to be used very rarely: these batteries, unfortunately, are very quickly heated and when charging, and with intensive work tools. In addition, nickel-cadmium batteries, despite the fact that they can rightly be called "veterans" in a number of chemical sources of current, in many characteristics still be superior to nickel-metal hydrides.

Nickel-Cadmium and Nickel-Metal Hydride Akb

Ni-CDs are the first alkaline batteries, the production technique of which was developed even at the end of the XIX century. However, due to the fact that for those times, the mass production of the battery was very expensive and required certain conditions, it began intensively only in the 50s of the twentieth century.

Despite the criticism of numerous fans of more modern batteries, Capacity indicators Nickel cadmium batteries have Not bad . И heated during operation much less What the same nickel-metal hydrides due to endothermic reactions occurring inside. If you recall the school course of chemistry, the endothermic reaction means nothing but the absorption of the heat released inside the element, and not the allocation of it into the external environment. Namely, it happens with NI-MH batteries .

If you compare the characteristics of batteries for the screwdrivers, based on practicality and safety, the cadmium acb will be significantly better. It is for this reason that they So far, are the most chassis for electric tools of household use. .

Cadmium batteries in the battery pack

More shortly, all the advantages of nickel-cadmium acb can be voiced in this way:

  • Significantly reduced risk overheating. They do not threaten to "blink" quickly or fail, unlike metal hydrides.
  • Durable metal case. Cadmium batteries have a good indicator of resistance to internal chemical reactions and excellent tightness of the metal coating. They can work well and at very low temperatures, to -40 ° C.
  • Long service life Under the conditions of proper operation - from 8 to 10 years without the need to change the battery pack.
  • Moderate, affordable cost Unlike more powerful, but expensive lithium elements.

In order for NI CD batteries for a screwdriver to produce all of its own lifetime, there are several effective recommendations for their operation.

Insofar as Deep discharge they are not afraid Working with a screwdriver should be up to the complete discharge of the battery pack. Then you can put the batteries charge, without fearing the fact that they will lose capacity: when charging, these batteries are quickly replenished. Keep them also better discharged - In this case, the so-called "memory effect" will be much smaller, and in the process of storage, no recharging is required.

"Memory effect", which has nickel-cadmium batteries for screwdrivers, is not really too much drawback. In order for them not "remembered" an unnecessary level of charging, you need to spend two or three complete charge-discharge cycles. Then all their best indicators will quickly restore.

In order for the "memory effect" manifested itself less and less often, you should not often recharge them. It is better to carry out full charging cycles, thereby "cleaning memory". It is this for a long time will provide nickel-cadmium batteries with greater productivity of work.

What can be said about Ni-Mh Akb, except what they are prone to heat? These batteries are less harmful to the environment. The "memory effect" is expressed less than the Ni-CD of the predecessors. But they will have to charge them more often, because the percentage of self-discharge these batteries are high. Popularity is inferior to Kadmiev.

Lithium-ion batteries and their advantages

It is the batteries based on lithium now constantly on rumor in many consumers. In part, due to the fact that the lithium composition is used everywhere, almost in any gadget, ranging from a smartphone and ending with a personal laptop. They appeared not so long ago, if we compare the time of their occurrence with nickel-cadmium - only in the 90s of the last century.

It is known that at first lithium-ion batteries had a great degree of explosion hazard due to technological flaws. At the moment the overwhelming majority are the most equipped Controllers charge level and heating, which provides them Security and increased productive time .

What is so noteworthy lithium batteries?

Consider their advantages in comparison with predecessors:

  • Higher capacity What increases the term of their continuous use.
  • No "Memory Effect" (At least, the sellers and manufacturers are so approved).

The high level of capacity ensures the successful use of this particular type of batteries in the technical tools of the professional plan.

Lithium battery screwdriver on charging

With all its advantages, lithium batteries very sensitive to the slightest voltage drops during charging , and to sharp temperatures . Of course, all chemical sources of current are subject to one way of sensitivity. But experts in the field of electronics do not accidentally call "capricious" this kind of batteries.

Unlike nickel-cadmium, lithium battery does not make sense to acquire with a margin. Over time, they lose their container if they do not use them for a long time , and their storage time is no more than two years.

Lithium or nickel-cadmium batteries - what better?

In fact, the question of which battery is better for a screwdriver, is not entirely correct. It all depends on the situation and the duration of time during which the tool will be used.

A lithium battery unit is less weighted with the same capacity indicators that cadmium. But this is not the main indicator, based on which you should choose the battery for the screwdriver. Definitely кThe number of cycles of charge-discharge in cadmium elements are many times less than that of lithium . Standard for Ni-CD. make up 500. , and for LI 1500. that, of course, at first suggests that lithium batteries are much better.

When choosing batteries, it is important to take into account the fact that The aging of nickel-cadmium batteries depends solely from the cycles produced by them, and not from their real age . The service life of lithium-ion batteries, unlike cadmium, directly depends on age by age. After 5 years, they will be out of order, even if they did not use them. Nickel-cadmium batteries, on the contrary, will live long even if they did not use the year or more.

For example, when buying a screwdriver, used, you should not take it with lithium batteries. There is a large proportion of the likelihood that if the tool has not been used for a long time, its battery pack is already unsuitable for use. If the used "Shurik" is sold with cadmium batteries, they can save up to 60% of charge, regardless of whether the worker was tool or not.

If the screwdriver is not used very often, lithium batteries rather "aged" than serve their laid 1500 cycles. Therefore, for periodic domestic use, it makes no sense to buy a tool with lithium batteries.

Cadmium can serve from 8 to 10 years, regardless of whether batteries are used, or not. He can also calmly lie in a warehouse, keeping his properties, unlike lithium. If you do not plan to use a screwdriver often, the answer to the question of how to choose the battery will be short and truthful: Choose cadmium.

By the way, when frost up to -20 ° C cadmium "leads" itself better than Lithium batteries that do not like big frosts . Lithium need to be stored in a charged state at least 60%. They need permanent recharging if not used . Otherwise, they begin to collapse.

So, if the screwdrity is not used intensively, for periodic domestic use, choose a tool equipped with a nickel-cadmium battery pack. If you work with a screwdriver daily and professionally - definitely, it will be better to stop your choice on lithium, because the batteries serve their laid 1500 cycles, will return and pay off the money invested in them. Do not overpay for unnecessary cycles if you do not use the tool often and constantly.

Thus it becomes clear that nickel-cadmium batteries are essentially no worse than lithium. The main question consists only in the application of both types of chemical elements of nutrition. When using each of them at the right time and in the right place, both and the other may be equally useful and good.

Battery (AKB) is a device that accumulates, stores and consumes energy. Reversible chemical processes occurring inside it make it possible to charge and discharge the battery many times.

Akb penetrated all areas of our life: from children's toys and household power tools before the automotive industry and the space industry. Their use of their diversity has created such widespread. In this article, consider the best accumulators for screwdrivers.

Types of accumulator batteries for screwdrivers

A variety of batteries is due to the fact that various chemical elements can be used as electrodes and electrolytes. The quality of the operation of the power tool used depends on the correct choice of energy to the energy tool. The following 4 types have received the greatest spread in the field of electrical appliances:

  • nickel-cadmium (Ni-CD);
  • Nickel-Metal hydride (Ni-MH);
  • Lithium-ion (Li-Ion);
  • Lithium polymer (Li-POL).

Consider more each of them.

Nickel Cadmium Battery Batteries

Despite the fact that this species appeared at the end of the 20th century, their mass production began only in the middle of the next century. In them, nickel is used as a positive electrode, as a negative - cadmium. Most often they have the form of a cylinder, for which they received the common name "Banks".

Nickel-cadmium acb, used for the operation of the screwdrivers, have several advantages:

  • can be operated at low temperatures without a special charge loss, which is a huge plus when working outside in the winter;
  • up to 1000 cycles charging-discharge;
  • There is no risk of self-burning;
  • high load capacity;
  • May be in the discharged state for a long time without losing their properties;
  • the possibility of restoring batteries failed;
  • You can exploit until completely discharge.

Despite the existing advantages of NI-CD AKB have some minuses:

  • toxicity of substances filling "bank";
  • complex disposal of exhaust devices;
  • high weight;
  • AKB self-discharge, which reduces capacity and voltage;
  • The effect of memory that occurs with the incomplete discharge of the battery and further reduces its container.

It should be noted that nickel-cadmium acb is recommended to be stored in a fully discharged state.

Nickel-Metal Hydride Rechargeable Batteries

The beginning of the creation of this type of elements is refers to 1970. However, the unstable work of the first samples necessitated the search for new metalhydride alloys. Only after the 80s, Ni-MH Akb was improved. The new type of battery has the following advantages:

  • they are practically not inherent in the memory effect;
  • In their production, toxic components are not used;
  • simplicity of disposal;
  • Capacity by 30% more than Nickel Cadmium;
  • lungs and compact;
  • Do not fear mechanical damage.

Minuses:

  • long charge;
  • 500-600 cycles charging-discharge;
  • After 300 cycles, it is possible to observe a decrease in capacity;
  • It is impossible to operate under negative temperatures;
  • It is impossible to discharge completely;
  • Higher cost in comparison with the previous view.

Store nickel-metal hydride batteries are needed half charged and in a cool place.

Lithium-ion rechargeable batteries

Li-Ion Akb appeared in the 90s thanks to Sony. The first elements of this species differed in high explosion. Only 20 years later they got rid of this problem. Currently, it is an acb with high characteristics and a number of advantages over previous:

  • short charge period;
  • There is practically no memory effect;
  • minimum self-discharge;
  • Capacity is not reduced when charging a non-fully discharged battery;
  • the absence of toxic components in the composition;
  • Long service life.

Despite the visible advantages of lithium-ion batteries, it was not without flaws:

  • It is impossible to apply mechanical damage, because there is a probability of explosion from impact;
  • Quickly fail with strong discharge;
  • not subject to recovery activities;
  • Quickly discharge at minus temperatures.

Lithium polymer batteries

This type of battery was developed on the basis of lithium-ion. The difference lies in the fact that the liquid electrolyte was replaced with the gel-like polymer. This, first of all, increased the safety of the use of these items. In addition, the capacity, and the weight and dimensions, on the contrary, decreased. So, the advantages:

  • no memory effect;
  • There is practically no self-discharge;
  • have a higher capacity than Li-Ion;
  • can be very thin (up to 1 mm) and various shapes;
  • Can be used in thermal conditions from -20 to +40 Celsius.

Disadvantages of Li-POL AKB:

  • service life - no more than 3 years;
  • expensive;
  • It is impossible to completely discharge;
  • Many nuances of operation and charging.

For screwdrivers, this type of batteries is rarely used, which is associated with their high cost.

It is difficult to unambiguously say what battery is better for the screwdrivers. Each type of batteries has its advantages and can be used in various conditions. For rare use, nickel-cadmium batteries will be suitable for everyday life, which can be stored for a long time without loss of properties.

Conclusion

We reviewed the most popular batteries, compatible with Bosch, Hitachi and Makita screwdrivers. As can be seen from the descriptions, each of them has a number of advantages: a large capacity, long service life, a small time of recharging, the ability to operate in a wide temperature range, etc. However, these advantages are rarely combined in one model. Depending on the chemical elements used as electrodes and these differences arise.

When choosing a battery item, it is important to determine in what conditions the tool will be operated (in the house or on the street), as it will often be necessary to occur in it. Not every battery transfers long-term inaction without losing its properties. After all, it is from the incorrectly selected working conditions, the charging and storage regime flows many discontent, which are not related to the quality of the AKB. Observing all the rules of operation of the battery provided for by the manufacturer, you will not only extend the service life, but also increase the level of comfort when working with the tool.

Home masters and employees of various construction organizations often deal with such a fairly convenient tool as a battery screwdriver. These devices are characterized by a long battery life, as they work from the battery. However, the situation is not discharged when the battery fully produces its resource, it begins to keep the charge or keeps it completely.

Acquire a new screwdriver due to the seed battery is unreasonably expensive, so it's better to buy a new battery for him. You can find a large selection of such devices on sale, but they can differ much from each other and from the original products on a variety of factors - voltage, connection connector, charge time, and so on.

Let's try to understand this issue together - we will define what batteries are, at what moments when buying it is necessary to pay attention. This will help us the rating of the best batteries for the screwdriver 2020. In addition, here we will make an analysis of the useful qualities of the most popular devices from users.

How to correctly pick up the battery for the screwdriver?

Most standard screwdrivers are equipped with electric batteries. They accumulate charges, and then transmit this energy to the cartridge. Each similar device includes an anode and cathode, the space between which is filled with an electrolyte that performs the function of the conductor. The main specificity of similar products is that all chemical processes occurring in them are reversible, therefore batteries can be used repeatedly.

Today, lithium-ion batteries are most common, which appeared in a wide sale relatively recently - a little less than 30 years ago. They easily hold a big charge in themselves, they have a so-called memory effect, so they can be charged at any time and not only after they completely discharge. These devices have minor overall dimensions and mass, which is important for working with autonomous tools.

What are the accumulators for a screwdriver

When choosing, it is necessary to pay attention to the battery capacity - this parameter determines how much time the tool will be able to work without recharging. Directly on the performance of the device affects its voltage. A high voltage model will work better and longer. However, for household screwdrivers, gain a battery with a voltage of more than 14 in undesirable, as this will lead to the rapid wear of other key parts of the device. The voltage is 18-24 in the best suitable for professional equipment.

When we chose products for inclusion in the rating of the best accumulators for the screwdriver, it was necessarily taken into account all the above points, however, some other factors were taken into account: the ratio of price and quality, as well as user reviews. We tried to make an overview of not too expensive products so that each reader could choose a device in its own means.

With the choice of power tools, buyers face constantly. And already familiarly oriented in the characteristics, with the mind choosing a new technique. With rechargeable tools, the situation is somewhat more complicated and the more interesting! In addition to the standard selection criteria, additional - the parameters of the batteries themselves appear. It is from this that the productivity of the instrument will depend on how much time it can work without interruptions to recharging and ultimately even its weight.

What batteries are that the characteristics affect their characteristics and what mistakes allow many to use battery tools - you will learn about all this from our article.

The device and the principle of battery operation

Electrical batteries are installed in the battery tools. They are able to accumulate charge, and then give the accumulated energy to power the electrical appliances.

In each battery there is a cathode (electrode attached to the negative pole), anode (electrode attached to the positive pole) and electrolyte between them as a conductor. Inside, chemical reactions with energy is constantly proceeded, which is then converted to the electrical necessary for the operation of various instruments and tools. The specificity of these sources of current is that the chemical processes in them are reversible, so they can be used more than once, and repeatedly.

The properties of batteries directly depend on the materials from which the electrodes and electrolyte are made. For the same principle, they are divided into types.

Types of batteries

Nickel Cadmium (NICD). This is an old type of batteries, which began to use widely in the middle of the 20th century. Nickel-cadmium batteries have two undoubted advantages.

First - A large number of charging / discharge cycles : in modern devices it can reach 1,000. Shelf life, thus, can reach up to 20 years. The second advantage is Ability to work in various temperature conditions .

But these batteries also have several significant drawbacks, among which the most significant - Big weight And the so-called "Memory effect" . Add to this that the production of such energy sources for tools pollutes the environment.

"Memory effect" - It is a loss of tank. If you constantly recharge the battery, then it remembers that the capacity is not completely used. And during the next inclusion for work, he gives energy only to the "stored" border.

Metal hydride nickel (NIMH) . The first new type batteries appeared in the early 70s of the 20th century. It was a breakthrough - NiMH batteries began to weigh significantly less than nickel-cadmium and the "memory effect" they almost absent. Their production does not pollute the environment.

But the disadvantage was the fact that nickel-metal hydride batteries have fewer charging / discharge cycles and is not recommended to operate with them at minus temperatures.

Note! NiMH and NICD batteries charge only after the battery is completely discharged. Frequent recharges reduce battery capacity.

Lithium-ionic (Li-Ion) . New generation batteries for the first time appeared in 1991. Sony was launched into mass production. They are very well holding a significantly greater charge than previous generation batteries. They have no "memory effect", therefore, they can be charged at any time, and not only when the battery is completely discharged. Weight and dimensions are reduced by 40% compared with nickel-metal hydride and nickel-cadmium batteries, which is especially important for professional battery tools, including for drills-screwdrivers, which are intensively used by masters throughout the work day.

Battery type NICD Nimh. Li-Ion.
Specific energy intensity 45-65 W * h / kg 60-70 W * h / kg 110-230 W * h / kg
"Memory effect" there is there is not
Number of cycles charge / discharge More than 1000. 300-500 600.
Self-discharge per month ten% 7-10% 3-5%
Storage conditions Fully discharged Partially discharged Fully charged
Charging conditions After full battery discharge After full battery discharge Anytime

Tool manufacturers independently continue the process of improving lithium-ion batteries and chargers for them:

  • Metabo's first has developed a new technology that allows you to cool the battery during its charging, thereby speeding up the entire process by 30%. If the battery is less heated during recharging, then the time you need to spend that it is fully charged, decreases. Metabo releases universal high-speed chargers for NiCD / NIMH and Li-Ion battery packs. They have a different charging time: the high-speed devices have about 15 minutes, and for charging the battery, the universal device will need to wait about half an hour.
  • Makita also improves its lithium-ion batteries. Since 2009, a built-in chip has appeared in them, which records all data: the frequency and intensity of use, the number of charging / discharge cycles, residual capacity, and so on. Thanks to the information received, the device automatically selects the best charging conditions of this particular battery. This made it possible to achieve Makita battery life by 280%!
  • Ryobi has released a series of one + rechargeable tool. Ryobi One + batteries are suitable for all products in this series, so one battery can also be used for a screwdriver drill, and for a saber saw, and for any other Ryobi One + tool. Their capacity is 1.7 a * h, and the voltage is 18 V. In this case, charging devices and Ryobi One + batteries can be purchased separately from the tools.

In our electronic catalog you will find rechargeable screwdrivers and other tools with any batteries. For example, at Makita 6347 DWDE Nickel-Metallhydrid Battery, Dewalt DW 907 K2A - Nickel-Cadmium, and Bosch GSB 36 V bucks two Li-Ion batteries.

A new round of development. According to the forecasts of scientists, magnesium-sulfur (Mg / s) batteries are capable of surpassing lithium. The research and active developments of scientists in this area are already being studied. Indeed, in the theory, magnesium-sulfur batteries are able to produce energy with a density of more than 4000 W * C / l when the Li-Ion energy density reaches 230 W * h / kg. The main problem is that the electrolyte has not been found capable of stabilizing magnesium and sulfur.

Important to select Parameters

Battery capacity Determines how much time the tool will be able to work without recharging. Consequently, the capacity is larger, the longer a screwdriver or any other battery tool will be able to work. The battery capacity is measured in a * h (ampere-hours). That is, if the accumulator drill is a screwdriver in specifications it is indicated that its capacity of 1 a * h, this means that during one hour the battery will give the current in 1 A.

Like network tools in power judge the performance, so the battery will depend on Voltage . Choosing out two batteries with the same capacity, keep in mind that the longer one that the voltage is higher will work. In drills-screwdrivers, a voltage range from 3 to 36 V. Rechargeable high-voltage tools are used to work with solid wood and metals. For example, 36 V screwdriver drill can be used to drill a large diameter holes in a metal, brick and wood. Tools in which the voltage is lower (10-14 V), serve to twist the fastening elements and drilling holes of a smaller diameter. And drills-screwdrivers with batteries 3-6 are suitable only to twist the fastener of small diameter (up to 5 mm). Tools with 12-volt batteries are most popular for home masters. Because it is precisely the perfect balance between productivity, the duration of work and the price of the instrument.

Note! Only those batteries are suitable for working with the tool, whose voltage corresponds to the nominal, recommended manufacturer. That is, it is no more and no less than indicated in the instrument passport. For example, if you install a battery with a voltage of 12 V instead of 16 V in a drill screwpit, then the tool performance is sharply reduced. If you use 36 in the battery instead of 18 V, the engine of such a tool will work for wear, and this will soon lead to a breakdown.

Usually, a battery (sometimes even two) and a charger for it goes together with a screwdriver. But their shelf life is limited, and if the tool is very intensively used, in the end there will be a need to change the old battery to the new one. In this case, it is worth staying on corporate products. Then there will be no doubtful in quality, reliability, service life, and, of course, the branded battery from the same manufacturer will definitely suit the drill-screwdriver. In our heading "Batteries" presented batteries and battery packs for instruments from domestic and foreign manufacturers, among them you can always choose exactly the one that needs.

Chargers can also be purchased separately, the main thing when you choose to pay attention to the type of batteries that they recharge, and the time required for charge. In this regard, universal charging devices are very convenient, which are capable of working with NiCD, and with NiMH, and with Li-Ion batteries. For example, DC18SE Makita is just following such charger, it can recharge the batteries of three types with different voltages (from 7 to 18 V).

Useful battery care tips

  1. Before starting intensive operation, charge and completely discharge a new battery. It is better to do this several times, because it reaches the maximum container only after 3 charging / discharge cycles. In a sense, batteries, like athletes, to exit full capacity, workouts.
  2. It is best to charge the battery at a temperature of +10 to +40 ° C. If the battery overheated, he needs to give time to cool. Some chargers independently follow the temperature and strength of the current, not allowing the batteries to overheat.
  3. Batteries should not be stored in the instrument.
  4. If the battery does not use more than 6 months, then it should be charged from time to time.

In order for the batteries steadily and for a long time, you need to follow the rules of their operation and avoid errors that can lead to breakdowns. More information about this, as well as many other useful information about chargers, you can learn from the article "How to extend the life of the battery?". And order the batteries suitable for your tool in our online store you can right now!
