The voltmeter should read 29 volts when on. You should never replace one battery and leave an old battery in the chair. Replace them both at the same time.
use a standard 7.5 volt dc fuse the speed lights will not blink when charging only the battery level lights will Make sure that your batteries are installed correctly... There should be two cables running to the fuse located at the rear of your chair one wire should be attached to the positive post of the front battery and the other wire to the negative post of the rear battery. The other cables should be color coded red for the positive post of the rear battery and the black to the negative post of the front battery. This will connect your batteries in series so you will be getting 24 + volts to the chair. The chair should then come on with the power switch on the joystick all the battery level lights should light up and the speed level lights will light up indicating the speed level you are set on. Once you have made sure that the batteries are wired correctly plug in the charger cord and you should get some deflection on the ammeter. When the ammeter reaches zero and kinda bounces up and down then you should be fully charged Hope this helps
Mary yep Even though the batteries are charging they are not holding the charge to provide enough power for the chair. Usually you have one battery that is weak and causing the problem but both batteries must be replaced. If Medicare paid for your chair then they will pay for 80% of the new batteries. You can contact the provider that sold you your chair and ask if they can replace your batteries. If not, you can contact Repair Express @ 1-877-581-3733 or Roadrunner Mobility @ 1-800-467-2668 to have tech come out and repair the chair for you and they will bill Medicare for the cost of repair. Hope this helps
Sounds like it might be time to change the batteries. Even if batteries are charged correctly they eventually lose power with use and need to be changed. Here is a link to the battery needed for the Jazzy 1103 Ultra http://www.replacementupsbattery.com/UB12350-NB.html
Romp, Did you check the freewheel levers chair will not move if you are in freewheel. Levers are in front next to seat posts and need to be facing forward. If you are not in freewheel then check the number of lights you have on on the joystick and that they aren't flashing. Also check that your speed control is not on the lowest setting even with some charge a slow speed setting will not let the chair move. Now by some charge you mean lights in the green on the joystick? If the lights aren't flashing then I'm kinda unsure other than even with some charge the batteries don't have enuf current to drive the motors and need to be replaced Hoe this helps
you need to have the batteries tested it is possible that if left in a discharged state for an extended time that thee batteries may be damaged and will not be able to be recharged
