Test charging of L-ion battery that won't take a charge
I have 2 18 volt Ryobi L-ion batteries same age 1 takes a charge the other doesn't.
In a earlier thread it was mentioned that when a battery gets so low the charger won't charge it but if it is charged slightly the sensor in the charger may then pick up the trace current & charge the battery.
Well I am trying this idea out. I taped a long screw in contact with 1 terminal & a short screw in contact with the other so that the clamps from the charger would be spaced apart I reinforced the electrical tape holding the screws with a thick rubber band. So far the light on the battery is now indicating that there is some current in the cells. I am using a battery trickle charger that I use to keep my Bobcat battery up over the winter it senses the battery charge & turns off & on the sustain the proper charge on the battery. If this works it will make me very happy .
