How to Charge Your Electric Wheelchair Batteries

As a power wheelchair user, it’s important to understand how to achieve maximum performance with your motorized wheelchair. Your Jazzy® power wheelchair uses two long-lasting, 12-volt, deep-cycle batteries, which are sealed and maintenance free. Because the batteries are sealed, there is no need to check the electrolyte (fluid) level. Deep-cycle motorized wheelchair batteries are designed to handle a longer and deeper discharge. While these batteries are similar in appearance to batteries used in a vehicle, they are not interchangeable. Vehicle batteries are not designed to handle a long, deep discharge, and are unsafe for use in electric wheelchairs.
 
It is important to use two wheelchair batteries that are the same type and chemistry and have the same amp-hour (AH) capacity.
 
The battery charger received with your Jazzy® electric wheelchair is essential in providing long life for your power wheelchair batteries. The charger is designed to optimize the performance of your electric wheelchair by charging the batteries safely, quickly and easily.
 
Use the off-board charger to charge your electric wheelchair:
  1. Position your motorized wheelchair next to a standard electrical outlet
  2. Be certain the wheelchair’s controller power is turned off and the electric wheelchair is in drive mode
  3. Plug the off-board charger into the off-board charger/programming socket on the controller
  4. Plug the off-board charger into the electrical outlet
  5. When the batteries are fully charged, unplug the off-board charger from the electrical outlet and then from the controller
The LED lights on the power wheelchair charger indicate different charging conditions at various times, including: charger power on; charging in progress; and charging complete. Refer to your owner’s manual for a complete explanation of these indicators.
 
If the LED light does not indicate that the charging is complete within 24 hours, unplug the charger from the outlet and contact your authorized Pride® provider.

Breaking in New Batteries for Your Jazzy® Electric Wheelchair

It will take a few “charging cycles” to establish the critical chemical balance that is essential to a wheelchair battery’s peak performance and long life. Take the time to properly break in your new electric wheelchair batteries.
  1. Fully recharge any new electric wheelchair battery prior to its initial use. This brings the battery up to about 90 percent of its peak performance level
  2. Operate your power wheelchair throughout the house and yard. Move slowly at first, and do not travel too far until you become accustomed to the controls and break in the wheelchair batteries
  3. Give the batteries another full charge of at least eight to 14 hours and operate your motorized wheelchair again. The batteries will now perform at over 90 percent of their potential
  4. After four or five charging cycles, the batteries for your motorized wheelchair will top off at 100 percent charge and last for an extended period

How Often Should I Charge My Electric Wheelchair Batteries?

How often you use your power wheelchair determines how often you should charge your batteries.
 
If you use your electric wheelchair daily, charge the batteries as soon as you finish using your power wheelchair for the day. We recommend charging your motorized wheelchair’s batteries for at least eight to 14 hours after daily use. If you use your power wheelchair less frequently, we recommend charging the batteries eight to 14 hours twice a week for a maintenance charge. We do not recommend charging the batteries on your power wheelchair for longer than 14 hours. Refer to the manual supplied with your wheelchair battery charger for additional information.
