How to Extend the Battery Life of Your Wheelchair or Scooter

Only drain new batteries by 30 percent the first week.

Charge your power chair or scooter when the lights or needle go from the green to the yellow to allow your batteries to achieve fully-charged status.

Charge batteries daily.

Leave your power chair or scooter plugged in overnight when you charge it.  A good 8-12 hour charge is ideal.  Even if the green light comes on in an hour or two, leave it plugged in overnight.

Avoid depleting them over 80 percent.

If you allow the batteries to fully discharge, they may not take a charge because the voltage level could be too low for the batteries to communicate with the charger.

How to Extend the Battery Life of Your Wheelchair or Scooter

Avoid overcharging your battery.

Make sure it is not attached to the battery charger for more than a 24-hour period.  Overcharging can cause permanent damage.  See image below.

Damage Scooter BattteryAlways use your own charger.

Never use a different wheelchair charger other than the one that came with your wheelchair. It can destroy your batteries.

If you’re going to store your power chair or scooter, charge it overnight once every two weeks.

Failure to charge it while storing it will result in a dead set of batteries. If you have a scooter with a detachable battery pack, please detach it. This will help keep down the parasitic drain from the scooter.

Avoid hot and cold extremes when storing batteries.

Direct sunlight and humidity can also cause damage to the batteries.

Water is not our friend.

Make sure when storing or charging your battery that no source of water can reach the battery.

Dust and debris also can interrupt terminal connections.

Make sure all terminal ports are clean and free of dust before charging.

Handle with care.

Always use caution when removing a battery from the power chair or scooter and handling it, and make sure it is stored in an area where it is safe from being bumped, or knocked down. Additional issues that could arise from dropping a battery are:

  • Damaging the terminal prongs of the battery
  • Cracking or breaking the battery case

Be Careful!

Batteries produce explosive gasses. Keep sparks, flames, and cigarettes away from batteries at all times. ALWAYS wear safety glasses and a face shield when working on or near batteries. Ventilate well. Do not install in an airtight container.

Read your manual.

Most manufacturers not only instruct the user on how to charge their equipment, but may also include a separate sheet with charging instructions.
