Rechargeable battery tips

Here are a few tips for maintaining the life of your rechargeable batteries on your power tools.

1) Don't run your batteries completely dead. There is a myth that says you should run your battery pack completely dead before recharging it. Completely not true.

2) New battery packs should be charged fully before use. Usually it takes several discharge/recharge cycles to get full life out of them.

3) A NiCd or NiMH battery will lose around 1% per day of it's charge. You should charge your battery packs every 1 -2 months when not in use.

4) Do not charge your batteries in extreme temperatures. Mainly its the cold that will kill your battery. When charged in a cold climate, condensation can develop inside your battery and cause corrosion.
