If you want your wheelchair battery to work for years to come it is best that you follow the below guidelines for maintenance and charging in order to get peak performance. The longevity of your wheelchair battery life also depends on choosing the correct battery for your daily usage. If you use your wheelchair quite often during the day, you will need to purchase a wheelchair battery with the appropriate capacity.


  1. Always refer to the wheelchair’s manufacturing guidelines before ordering a replacement SLA wheelchair battery to ensure you are purchasing the correct battery. You will again need to refer to this guideline before installing.

  2. Always use the charger supplied with your wheelchair, and make sure it is set to the proper battery type. Never use an automotive charger.

  3. Under normal everyday use, most people need to charge their wheelchair daily. If you need to store your wheelchair for a long period of time, it is best to charge your battery at least every 2 weeks.

  4. Do not overcharge your wheelchair battery. Most chargers are equipped with a warning indicator light to prevent overcharging. If your model does not have this feature, is best not to charge the battery for more than 24 hours.

  6. Extensive exposure to heat and cold temperatures will reduce the capacity of your wheelchair battery and may even cause damage. Wheelchairs should be stored in an insulated, heated area at all times in order to avoid premature replacement.

A properly maintained wheelchair battery should last approximately for two years if you follow the above, recommended tips. If you are following these recommendations and you find that you are not getting the performance you need out of your SLA wheelchair battery, it may be time for a quality replacement.
