What size battery?
If it's household batteries, some of the really good chargers (Lacross 800/900/etc) have a fancy cycle that can bring back dead rechargeables if they're not beyond resurrection.
Look at Amazon's reviews on the rechargers or even rechargeable batteries, and read over NLee The Engineers posts.
Hope something here helped.

If the battery is totally flat, you may be able to give it enough of a kick with a DC power supply to get it to charge again but I wouldn't count on it holding much of a charge. NOTE: make sure that you have your polarities correct and only use the rated voltage of the battery

Sorry all, I was talking about NiCd batteries that are used in home power tools. I have a lacrosse battery conditioner and it is indeed awesome, but I'm trying to fix a power tool's NiCd battery pack.

@sirlouie: recycle and replace = fixed

You can (allegedly) have the packs rebuilt with new cells at places like BatteriesPlus.

I freeze my rechargeable Xbox battery packs when they won't charge.
Freeze em for a few hours, let them thaw and then charge. Works majority of the time.
