Hey guys, I haven't been on here in quite a while, a few family issues to take care of. I bought a couple regular automatic batteries back in March. I charged them both (until the light turned green)...So I go to take a drag and the battery just keeps blinking like the battery was dead. So I decided to charge them up again, the light turned green and same thing happened. Is the battery done? How long should these batteries last? Are they still under warranty? Thanks for your Help.
