Battery and Charger

What are batteries and chargers for tools?

A power tool battery is a consumable item for operating cordless power tools independently of power outlets. As long as the battery holds a charge, the tool works. When the power runs low, you can replace the battery and continue working.
The battery can be inserted in seconds, but everything depends on its condition: RPM, torque, stability under load. The charger is no less important here. It supplies current at the correct voltage and ensures there is no overcharging or overheating. If the charger is of poor quality, the battery will not last long.

Applications of batteries and chargers

Power tool batteries are used in drills, impact wrenches, grinders, trimmers, and jigsaws. In a workshop or during repairs, using cordless power tools offers convenience, speed, and independence from power outlets.
However, when working on-site where there is no power outlet, autonomy is everything. When power tools are used in conditions without access to electricity, a spare battery is often more important than an additional attachment.

Types of batteries and chargers

There are several types of batteries: lithium-ion (Li-Ion), nickel-cadmium (NiCd), and nickel-metal hydride (NiMH). The most common and modern are Li-ion. They are lightweight, have a built-in controller and thermal protection. However, they offer greater capacity and autonomy, but also greater weight. 
Power tool chargers are mainly divided into pulse and transformer types. Pulse chargers are modern, lightweight, and automatic. Transformer chargers are heavier but reliable and classic in design.
In terms of operating speed, there are standard and fast chargers, which can charge a battery in approximately 30-60 minutes.

Advantages of batteries and chargers

Modern Li-ion batteries are lighter and more stable than older models. They do not “sag” immediately after half charge and withstand many cycles. Capacity in amp-hours affects run time. Voltage affects power. A charge indicator helps prevent the tool from suddenly stopping.

Recommendations for choosing batteries and chargers for tools

Before buying a charger or a new power tool battery, check the model and compatibility with your tool type. This is basic, but it's where mistakes are most often made. Also, pay attention to amp-hours and voltage.
If you work regularly, it's better to have a spare power tool battery. One charges while you work with the other.
