you can but it will take longer to charge and prob will be at 16 volts give or take 1 volt.

Don't even bother to try repair either of them, Take them back to the dealer under warranty and make them his responsibility, If you try repair them the warranty will fall away.

I'm afraid not. It will damage the battery if you try. You'll need to get the correct charger.

Try to discharge the batts to the full end.Then try charge them agian for at least 12 hrs.

I included both, just in case you have a corded version too, since sometimes the Fixya site provides "fill in" information for askers.

I hope you find this Very Helpful and best regards!

take a hammer, and apply force. These batteries dont last forever... but i am serious about the hammer... you may be able to free up whats inside (if you know how a batterey works.)... also apply heat.. try to hit it from all angles than slam it down on the back and leave it sit... than try. I hope this works for you my dewalt batteries over the years have don this, and it works.. but BTW. it wont hold a charge for very long anymore.. the battery is pretty much garbage.

Yes you can replace the inside batteries yourself , just take the old ones out and go to Battery world or a similar shop and get replacements then all you have to do is repack them yourself and put them back into the battery case .
