Still your batteries are bad. Had this problem before. If the batteries are more than 1 to 2 years old they need to be replaced. The charger only tells you it can't charge anymore, because the battery is sulfated. The meter on the chair is telling you the batteries are not strong enough to run the chair.

check with your operators manual and you may find a switch that has the markings of a hare on one side and a tortoise on the other
that will be you low and high speed settings

It appears that the controls are in Lock Mode. Unlocking Instructions depend on your type of controller. Go to PrideMobility.com to download the proper manuals for chair and controller.

Without the charger the batteries would go dead. You could put a voltmeter across the batteries and you should read more than 28 VDC while charging.

The chair should have a meter on the rear panel where the 9 pin connector for the joystick plugs into the chair when you plug in the charger cord the meter should move up and the lights on the joystick should flash indicating the charger is plugged in. When the chair is fully charged the meter should read zero or bounce up and down. Hope this helps

Yes prob one of the batteries are bad, but you may want to replace both.

Just had this problem with my Guardian Aspire. They had to replace the electronic box with the joy stick. BIG BUCKS!

Firstly disengage the drive levers and then "flick "them in fash.
Second pull out the large plug that is between them.
Check for damaged or bent or loose pins. press it home firmly .
I did this on my wifes chair and she zooms around.
All switched etc should be off during charge.

Lastly i fully discharged then recharged the battery to ensure no "battery charge memory".
To fully dicharge i shoved a small box between back wheels so to lift of ground and then a elastic band to hond controler on.
