With a full charge chair stops working and won"t power up

The batteries are too low for the charger to work. You need to take the batteries out and charge them separately with an automotive battery charger. This may take 2 or more days for each battery. When the voltage on the battery gets past 10 volts, you can put them back in the chair and finish the charging with it's charger.

Did you charge it at all during the 3 months? Did you store chair on a full charge? Check to see if batteries are dead. Batteries should be disconnected and/or stored on a full charge. If left connected they should be fully charge every week.

the motors may have won brushes or the brakes are hanging up causing high battery usage

The green light on your charger indicates a full charge but you know thats not right since you didn't charge the batteries when they were in storage they have dropped so low the charger cannot detect them and provide a charge. The batteries will need to be replaced with new ones. Charge before use and charge for at least 20 days to get them operating at 100% now you will have to use it for those 20 days to get the batteries used to charging charge every night when you go to bed and unplug when you get up in the morning. If you do have to leave the chair for a week or so put up fully charged and charge once a week overnight. If you put the chair in storage again disconnect the batteries from the chair and store with a full charge. Hope this helps you

Cathey when you plug in the charger look at the rear of the chair at the meter if the chair is charging then the meter will indicate some amperage reading when it is fully charged the meter will read zero. Also turn on the chair and if the lights are scrolling or flashing it shows that the charger is plugged in. Now if after the meter reads zero (if it ever does) the lights on the joystick should all be lit indicating a full charge. If you aren't getting all the lights and the meter indicated the charger was working then you need to replace the batteries Hope this helps

I would replace the batteries with new ones anyway to make sure that you are getting full power and if the problem stops great if it continues then you have eliminated one possible problem. A low battery will cause the problem and these chairs diagnose themselves with the controller giving you flash codes to indicate a problem. I would just check for a loose connection in the wiring when you have the seat off changing the batteries and give the base a good cleaning( without water) (Use those cleaning wipes from dollar store) Hope this helps you

Hi Susan, I repair power wheel chairs, Its possible that your chair has a bad battery on it , all p/chairs have 2 batteries.And even though you show a full charge one battery may have a bad cell in it you need to get both batteries load tested . I think you my find one of them bad. take them out of chair and have them tested.You can get replacement batteries , and have yours tested at a store that sells batteries only, look in yellow pages for a battery store . Good luck, Erik

Here's the flash codes for the PG drive on your chair. count the number of flashes between pauses and match it up to see what the fault is.

Many a times batteries shows you full charged but due to some reason few of the battery plates are not working, and it will only work till the charged plates get discharged.

Batteries plates turns weak or get damaged due to non use of batteries, or expiry.
