Default Re: Optima battery will only chug to 50%

I bought one of the small Optima chargers and have used it to breath new life into several Optima's. I just checked the 10 year old Optima in my delivery and it was still at 75%, didn't take long to bring it to 100%. Don't know if it'll last under everyday use. I'll probably replace it as I have the car sold and wouldn't want it to fail for the new owner?
