I have a Ridgid 3.0ah battery that I purchased with a Ridgid radio. The person I bought it from said that they both came from a tool lot auction so going through the lifetime service agreement is not an option. He said he used the battery in the radio and it worked fine but once it died, he had no way to charge it and it sat for about 6 months before he decided to sell it. I bought it and when I put it on the charger, the EVALUATE light flashes for about 30 minutes and then the DEFECTIVE light will flash. There are no indicator lights that come on when I push the button on the battery itself and with a multimeter, its reads 0 volts. Physically, it's in brand new shape which leads me to think it hasn't seen much use, but maybe there is something I can try before it gets recycled. Thanks.
