It may still be under warranty. What kind of reading did you get from the batteries? If they are below 12.0 volts they may have a poor memory. If you leave a chair un-charged for a long period of time the batteries can discharge to a very low level. The charger cannot bring a battery up from 11 voltsDC. You will need a slow car type charger or new batteries.
