I'm sure you've all been here before, haven't used your battery operated tools in a while, and you find your battery dead. Try to charge and you get a "battery defective" light sequence on your charger. Another one bites the dust.
Did some research today since I was down to 1 18v battery for my Ryobi stuff (threw the other two out very early this year for the exact above reason) and of my two 19.2v Craftsman batteries, one was showing bad, the other was able to charge.
Very simply, I know most of us have a charger at home with either a 1.5 or 2 amp trickle charge setting. Hook it up to your battery on the low setting for about 5 minutes, then throw it on your charger. VOILA!!! It should now be showing it's charging.
The Craftsman 19.2v stuff was pie to hook up. Amazingly a spade terminal fits directly on the terminal in the battery.

In the pic, the left is the negative, right is the positive.
On my Ryobi battery, the positive and negative are marked, but I had to use a rubber band to hold the battery clamps to the terminals.
DO NOT TRY THIS WITH LITHIUM ION BATTERIES. NI-CAD ONLY.
Hopefully this helps some of you out. I saved two batteries today via this and am now kicking myself for tossing my other two ryobi ones in Jan.
Oh, and for the inquiring mind........I had to cut holes in sheet metal. :D That is all.
