Was given a jazzy with new battery just replaced it worked when we brought it home , sat with out being plugged in or 4 weeks plugged it in to recharge it and it will not hold a charge or move.

SOURCE: Battery holds a charge for a short time only

These phones are known for the contacts not transferring adequate voltage to fully charge the phone.

SOURCE: My Jazzy won't move.

If your batteries are truly charge they should read around 24.5 VDC. And if the freewheel lever is engaged and you still have no movement your probably need to get into a service tech. Also check the circuit breaker on the chair.

Are the batteries really gettin a full charge or is your charger faulty. If you can borrow a voltage meter you can see what your battery is putting out and check the charger (plugged in) to test how much voltage it is putting out. If the Razor is 12 volt you can hook up a car/motorcycle charger to pump up those batteries. I don't think your batts are not holding a charge, i think they're not gettin a charge....good luck to you...Tim

you have either bad batteries or a bad charger or the charger might have come unplugged at the controller or power module. When you have the charger plugged in and you turn on the joystick the lights on the joystick should ripple to indicate the charger is plugged in. If you don't see this ripple then either the charger is bad or disconnected. Trace the charger cable from the rear of the chair (you have to remove the seat and shroud to do this) to the front module and make sure that the cable is plugged in. Hope this helps
