No, it's showing that the battery is either not taking a full charge or the charger is not charging the battery properly. Find a Milwaukee service center, they will check them and most likely replace one or the other.

Do not try to repait the battery. There is a possibility you could fix it but don't try it. Acid is not friendly on humans body.
go out and buy new batteries for it. I would suggest you buy the type of battery it came with.
One more thing; Make sure you remove the battery and store it in a normal temperature area anytime it is not in use.
