How to get the longest life from your mobility batteries

  • Fully charge the batteries before first using them.
  • Never allow batteries to run completely flat.
  • If you use your mobility scooter or wheelchair every day, recharge the batteries every day.
  • If you use it weekly, then recharge when you have finished using it.
  • If you are storing your scooter for more than 6 weeks, fully charge the batteries and then disconnect them. Check and recharge the batteries monthly.

Remember that most scooter and wheelchair batteries need several charge-discharge cycles to get to their full capacity.

Charging and chargers

Always use the automatic charger supplied with your vehicle. Never use a car-type charger.

Keep the charger on until the light on the charger shows fully charged and longer if possible – usually overnight. So long as the correct charger is being used, you can leave it connected and turned on until you need to use the scooter or wheelchair again. The charger continues to provide a very low trickle charge (at minimal cost) that keeps the batteries topped up and ready for use.

If necessary, you can give the give the batteries a short charge so you can use your scooter. It’s better not to risk a flat battery while you are out, but doing this repeatedly will reduce the life of the batteries.

If you want to turn the charger off, disconnect it from the batteries once they are fully charged. This makes sure the batteries can’t discharge through the charger. Remember that the batteries will slowly drain even without use, so if there is no trickle charge, you should check and recharge from time to time.


Most mobility scooter and powered wheelchair batteries are sealed lead-acid ‘deep cycle’ batteries. They need no maintenance apart from regular charging and because they are sealed, they can’t spill.

The batteries achieve their full capacity after about 10 to 15 charge and discharge cycles, so when new, the range of the scooter or wheelchair may be less than expected. The battery capacity increases from about 60% to 100% during this initial conditioning period.

The lifespan of scooter and powered wheelchair batteries depends on usage, and is extended by using the recommended charging cycle. If you use your scooter once or twice a week, the batteries can last up to three years. For a scooter or powerchair in daily use, expect a lifespan between 12 and 18 months.

Scooter and wheelchair range

The range of your scooter or wheelchair depends on various factors including:

  • Condition of batteries
  • Weight of the vehicle and user
  • Tyre pressures and terrain
  • Ambient temperature

If the temperature is below freezing, range will be noticably reduced, while high temperatures (above about 35oC), increase the self-discharge rate in storage.

Air travel

Most sealed mobility batteries can be transported by air and are marked on with a sticker explaining it is IATA approved.
