Latest innovation in power tools. Li-Ion produces a longer run time, more power and better performance in extreme temperatures. It also has a low discharge rate when not in use meaning it will minimize having to charge the battery before use. The new Li-Ion batteries include a push button fuel gauge on the front of the battery indicating the amount of power remaining. As the battery is used, the indicator will glow green, yellow and then red to indicate it is time to recharge. Will fully charge in only one hour with the new and improved charger. This battery REQUIRES the use of the new and improved charger (#25926). Increases the performance and run time of all the Craftsman C3 tools. Some up to a 200% increase over their Ni-Cad counterpart.
