4 best screwdriver batteries
The best types of batteries for a screwdriver
Today in the domestic market there is a large assortment of different types of batteries for screwdrivers. Each of them has different, both positive and negative properties, which allows the buyer to choose the most suitable option for solving the tasks. The rating review compiled by us will help you understand the advantages of different technological solutions for batteries.
4 Nickel metal hydride battery
Rating (2022): 4.2
Many countries have banned the use of Ni-Cd batteries due to the toxicity of cadmium, and as a result, the popularity of metal hydride batteries has skyrocketed. In addition, Ni-MH batteries have the following advantages:
- The memory effect of the received charge is significantly reduced;
- The battery can be restored;
- The dimensions and weight have decreased, and the battery capacity has increased;
- Resistance to mechanical damage.
And the main advantage is the absence of any toxic components.
Despite significant improvements in performance, Ni-MH cells could not completely squeeze out their predecessor from the market, and it's not just the cost of this product (it is significantly higher than that of Ni-Cd batteries). Metal hydride batteries do not have the strongest sides, namely:
- It is not recommended to use at negative temperatures;
- Can quickly sit down, you can not allow a full discharge;
- When connected to the memory, it takes a very long time to gain maximum capacity.
In addition, these batteries have a rather short resource, they can withstand only 500-600 operating cycles. Despite this, Ni-MH batteries for screwdrivers are in demand, and any buyer can choose models with the characteristics he needs.
3 Lithium polymer battery
Rating (2022): 4.5
The most modern type of battery, working on the same principles as Li-Ion batteries. Technological excellence is expressed in the replacement of a liquid electrolyte with a gel-like substance based on polymers. Thanks to such changes, the weight of the batteries was reduced, their safety increased (not prone to explosive destruction), and the capacitive characteristics of the batteries increased significantly.
Batteries of this type are not widely used due to their high cost, but no manufacturer can afford to refuse a modern innovative product. For this reason, Li-Pol is included in premium screwdriver models. In addition, they still have a rather low operating life (2-3 years), limited to 500 battery charge cycles, and high requirements for operating conditions.
2 Li-ion battery
Rating (2022): 4.6
As a more advanced and technologically advanced product, lithium-ion batteries uncompromisingly “squeeze out” their predecessors in the market, even though they have a higher price. Their distinguishing features are the following properties:
- The specific capacity of the battery is almost 2 times that of Ni-Cd batteries;
- Light weight and compact;
- High electrical density coefficient;
- No toxic components.
Due to the absence of the memory effect, the capacity of the device does not decrease during storage, and recharging can be carried out when and how much is needed, without harming the battery at all.
No matter how convenient the lithium-ion battery is in operation, it also has its drawbacks:
- Small resource;
- Explosiveness;
- Not recoverable;
- Poorly tolerates negative temperatures.
The main repulsive factor for this type of battery is the high cost. However, the high charge level and extraordinary lightness (which is of great importance for large volumes of work) make the battery in demand on the market.
1 Nickel-cadmium battery
Rating (2022): 5.0
Batteries of this type have long proved their reliability and durability. It was the nickel-cadmium battery that was chosen for the first models of cordless screwdrivers. Despite its large size, this capacitive storage device has many advantages:
- The number of allowable charge cycles exceeds 1000;
- Generates high current and stable voltage;
- Does not lose its characteristics at low temperatures;
- Retains functions during long breaks in operation.
The above properties continue to be relevant today. When thinking about what type of battery is needed in a screwdriver, many owners choose a nickel-cadmium battery.
Despite these advantages, there are also disadvantages:
- Memorization of the amount of charge received (you can not connect a battery that is not completely dead to the memory or suspend the process until the maximum capacity is reached - otherwise this indicator is sharply reduced, which leads to battery failure);
- Toxicity of cadmium (requires compliance with disposal regulations).
It was the latter characteristic that became the main reason for the decline in the leading positions of these batteries. Despite this, a significant part of the power tool is equipped with Ni-Cd batteries.
The best battery manufacturers for a screwdriver
Despite the variety of these products on the market, the choice of most buyers is limited to a narrow circle of the best products, the characteristics of which, as a rule, the owners learn from their own experience. This category presents manufacturers of the best batteries for this power tool.

Subject to the rules for charging nickel-cadmium batteries, they are able to perform their functions for a long time.
Depending on which model of screwdriver needs a new battery, the buyer has a choice of the presented range of batteries with a voltage of 12, 14.4 or 18 volts. Decent build quality, reliable batteries and an affordable price have made Interskol products one of the most popular power tools on the market in the category of budget models.
3 DEWALT
Country: USA
Rating (2022): 4.6
The main feature of the battery products of this brand is the absence of ventilation holes on the battery case.Full tightness prevents building dust from settling on the connecting contacts, and also avoids a short circuit due to the ingress of any liquid. This became possible thanks to the use of a special plastic obtained using nanotechnology as a material for the case.
The company produces products with different types of batteries, and the buyer can choose a model with the best parameters for his screwdriver. So, among Li-Ion batteries there are real "monsters" with a capacity of 6 Ah (18 V). The battery is designed to withstand high intensity and load, without distracting its owner from the work to restore the battery charge. The quality of DEWALT products is of such a level that it allows the manufacturer to take on warranty obligations for a period of three years. For a construction tool, this, you see, is a lot.
2 Bosch
