Dewalt charger issue..

[jshultz78]

I've got a Dewalt radio/charger that I'm having issues with. The radio works fine, but when I plug in a battery, the LED blinks fast, going by the sticker it says "replace pack", but there's nothing wrong with the pack, it does it with two 18v, and my 12v. They charge fine on the regular charger. Is there a fuse or something inside that I can change?

Is the battery hot from use ? Sometimes mine will do that when the battery is hot (warm to touch) and I take it back out of the charger and let it cool for 15-20 minutes.

Nope, it just started doing it all of a sudden. It worked one day, went to put a battery in the next day and nothing..
