Understand cordless tool batteries
Cordless tools use rechargeable batteries to provide the energy needed during work. Battery capacity, voltage and technology affect runtime and performance.
Battery voltage
Voltage is an important characteristic of a tool’s power supply system. Different voltage levels may be intended for different applications and power needs.
Capacity and runtime
Battery capacity affects how long a tool can operate before needing a recharge. Actual runtime also depends on workload and operating conditions.
Battery technology
Batteries used in modern tools incorporate technologies designed to offer a combination of capacity, weight, lifespan and performance. These characteristics can vary by system and manufacturer.
Charging systems
Chargers restore battery energy and keep batteries available for further work. Use charging systems compatible with the battery and tool.
Compatibility between batteries and tools
Not all batteries are compatible with all tools. Before buying an additional battery, check the system, voltage, connections and compatibility specified by the manufacturer.
Advantages of cordless systems
Cordless systems offer greater mobility and allow work without depending directly on a power outlet. This can be especially useful for jobs that require frequent movement.
How to choose according to your needs
When choosing a cordless tool, consider voltage, battery capacity, runtime, charging time, type of work and compatibility with other equipment in the same system.
Understand tool battery systems
Knowing the relationship between voltage, capacity, runtime and compatibility makes it easier to compare cordless tools and select a system suited to your work needs.
