The Makita CXT 10.8/12v Batteries power the full CXT range of cordless 10.8/12v Makita power tools. The BL1021B is a 2.0Ah model which offers impressive runtimes.

This Lithium-ion slide on battery is compatible with the full CXT range. Because of the new build and cell structure the new slide on 10.8/12v batteries can offer higher capacities and have individual cell monitoring for added protection and longevity. 

It can perform in temperatures down to around -20^0c  and because it has a multi-contact slide terminal, it will stay sercure and opperational during extreme vibration.

There is also a very handy on board battery state indicator (fuel guage) which using 4 LED lights shows users how much charge they have left.
