That would depend on both the charger and cordless tool. A lot of chargers will charge NiMH batteries, and a few others will charge Li-Ion. However, even if your charger will do this, your power tool might not. It is best in these situations, to check your user manual or contact the manufacture to find out the technical specs of your model.

Can I recharge an old power tool battery after it seems to have stopped taking a charge?
There is a belief that you can recondition your old nickel based battery. Nickel based batteries will crystallize after a period of time and use. Some people say that you can break up the crystallization by running the battery at a very low volt (.5V or less) over a long period of time, and doing this over and over a couple of times as the battery drains. However this process can take a long time and has not been scientifically proven to work, so in most cases, your best bet is to replace the old battery.
