Chances are the battery has had it. If you totally flatten a battery it sometimes won't take a charge. It might show healthy voltage but that doesn't mean it's charged.

 

Try charging it at very low current for a couple of hours first, under 500ma can sometimes prime the battery so it will then charge off a standard charger.
