ITS Expert Says
This is your ticket to the Dewalt XR 18v Lithium-ion platform. The fastest growing cordless tool platform around. This battery allows you to use any Dewalt cordless tool in the range and there is over 100 to choose from.
This battery is NOT compatible with FlexVolt tools as it doesn't produce enough power to fuel them.
Remember - with batteries the higher the Ah the longer the runtime... not more power! A 3.0Ah could last 30mins doing a task - a 5.0Ah could last 50 mins doing the same task - they both produce the same amount of power it's just that the 5.0Ah will last longer!
