Battery Capacity and Voltage

This 21V lithium-ion cell delivers 2.0Ah of capacity for cordless tools. It suits DIYers and homeowners who need reliable energy for drilling and driving tasks around the house.

Build and Daily Use

The pack uses a plastic housing that keeps weight low for one-handed operation. Its form factor matches the original tool interface so it clicks in place without adapters or loose fits during overhead work.

Charging and Runtime Benefits

A full charge supports extended sessions across wood, plastic or metal without frequent top-ups. Users can complete a day of assembly or repair jobs before the battery needs to return to the charger.

Questions about this item

What voltage does the 21V lithium-ion battery use, and what capacity does that provide?

The battery operates at 21V with a 2.0Ah capacity, giving 2000mAh of runtime for cordless tools.

What physical size must the tool compartment accept for this battery to fit?

The battery is built to the 10-millimetre maximum chuck size used on the compatible drill, so the tool's battery bay must match that form factor.

How is the battery installed, and what step do users often miss?

Slide the battery into the tool until it clicks, then ensure the drill bit is fully tightened in the keyless chuck — a loose bit causes power loss that looks like a battery fault.
