Batteries for powered mobility equipment

 A guide to maximising the performance and lifespan of batteries for powered mobility equipment
No vehicle performs to its full potential without an efficient fuel system. Electrically powered wheelchairs and scooters are no exception. The Batteries fitted to powered wheelchairs and scooters act as their fuel tanks and should be topped up and well maintained accordingly, for users to enjoy the full freedom and mobility they expect.
 
Common questions and answers
Q.When should I charge mobility vehicle batteries in order to get the most out of them?
A. If your vehicle has gel batteries (Most powered wheelchairs)
• Fully charge them to begin with.
• Recharge them when the battery gauge shows a low charge. Be careful not to get stranded with
  Flat batteries!
• Recharge them once a week in any case.
• After around 20 charges, when the batteries have reached their full capacity, you should change tactics and
  Charge them when you have finished with the vehicle for the day, then: Once, say every two months, let the   
  Batteries discharge as you did when they were new before recharging them.
 
Never allow batteries to run completely flat.
A. If your vehicle has sealed lead-acid batteries (Most scooters)
• Fully charge them to begin with.
• Recharge them when you have finished with the vehicle for the day or if you are unable to do this, charge them
  Once a week.
• Every two months, let the batteries discharge until the battery gauge shows a low charge.
 • Never allow batteries to run completely flat.
 
Q.How should I charge mobility vehicle batteries?
A. Whatever types of battery your vehicle has use only the automatic charger supplied with the vehicle.
• Allow the charger to complete its charge cycle, until the green “fully charged” light on the charger shows.
  This may take 12 hours or more in some situations.
• Leave the charger connected and turned on until you need to use the vehicle again. The charger will then keep  
  The batteries topped up. If you prefer not to leave it turned on, the batteries will not be kept topped up, so you
  Should instead recharge say once a week.
• Do not leave the charger switched off whilst connected to the vehicle – some chargers will allow batteries to   
  Drain quite quickly if you do his. Always disconnect the charger from the mains when disconnected from the
  Vehicle.
  
 
Q.When will my batteries need replacing?
A. Occasionally, depending on many factors, batteries will need replacing after 12 months.
More commonly, they will still be going strong after two or more years. As they grow older, their capacity reduces. It is time to replace them when you find that the battery gauge on your vehicle shows a low state of charge after your day’s use.
 
Q.What is the factors that can affect range on powered mobility equipment?
A. Weight of the vehicle or user, ambient temperature, state of battery charge, tyre pressure and terrain can all affect the range of a battery. If the temperature ranges outside of our yearly averages, i.e. above 35 degrees Celsius and below freezing, this will affect the range of the battery. If the battery’s “state of charge” is low, then consequently the battery capacity will be low.
