I have a 3 year old battery that failed (for the first time) to charge on any charger. All 5 leds were red. It was showing 51.7 volts at the terminals. I connected it to a good battery (+ to + - to -) with some 22 gage wires for about 2 minutes. The wires got warm but that was all. The battery then showed 1 green bar. It was a little quirky to charge taking several attempts but it finally charged. Used it today and it was fine. Recharged normally this evening. This is on youtube but thought I'd post it here with the follow up that it seems to be fine now. Probably not long for this world but I'll get a little more time out of it.
Thought was the skinny wires would melt before any battery damage occured.
