Power Tool Batteries are rechargeable energy packs specifically designed to power cordless handheld equipment. They convert stored chemical energy into electrical energy, delivering the consistent voltage and current that modern power tools require.
Key Characteristics:
-
Chemistry: Most commonly lithium-ion (Li-ion) for high energy density and low self-discharge; older systems may use nickel-metal hydride (NiMH) or nickel-cadmium (NiCd).
-
Voltage Ratings: Available in a range of nominal voltages (e.g. 12 V, 18 V, 20 V, 36 V), which must match the tool’s requirements.
-
Capacity (Ah): Measured in ampere-hours (Ah), indicating runtime—higher Ah yields longer operation between recharges.
-
Form Factor & Connectors: Slide-on packs or bayonet-style modules; connectors vary by manufacturer, so compatibility is crucial.
Typical Applications:
-
Cordless drills, drivers and screwdrivers
-
Impact wrenches and ratchets
-
Circular and reciprocating saws
-
Sanders, routers and multi-tools
-
Outdoor equipment (trimmers, blowers, hedge cutters)
Selection Considerations:
-
Compatibility: Always choose the correct voltage and connector type for your tool.
-
Runtime vs. Weight: Higher-capacity packs run longer but add weight; balance according to your needs.
-
Charge Time: Faster-charging batteries minimise downtime, especially in professional settings.
-
Cell Quality & Management: Advanced battery packs include built-in electronics (BMS) for cell balancing, over-current protection and temperature monitoring.
Together with a compatible charger, Power Tool Batteries enable true cordless freedom—allowing professionals and DIYers alike to work safely and efficiently without the constraints of power cords.
