Batteries for power tools and other commercial devices can often be repaired by replacing one or all cells. Finding a NiCd and NiMH cell is relatively easy; locating an appropriate Li-ion cell is more difficult. Quality Li-ion cells are not readily available because a reputable battery manufacturer only sells to certified pack assemblers(See BU-305: Building a Lithium-ion Pack) In addition, quality Li-ion cells may only be available in high quantity, leaving smaller service enterprises in a disadvantage.
Engage your drive belt and start the chainsaw while applying gentle pressure on the belt. Keep it going until it starts to charge the battery. While this method works, it can be potentially risky because unguarded belts can go spinning at high speed. Take extra precaution when doing this procedure, or don’t attempt it altogether if you’re unsure.

This situation will cause your battery to have a reduced capacity and will lead to premature failure and a loss of performance under load.
