Scooter Battery Replacement



If your mobility scooter or powered wheelchair is going a bit slow or stopped then you probably need new batteries. Unfortunately batteries don’t last forever, so you can expect to have to replace them every 3 to 5 years depending on how much you use them.

At Prime Comfort we offer a large range of quality mobility batteries and a battery replacement service – contact us on 01476 560044.


When your batteries are new, it’s a good idea to keep them charged as often as possible, this will keep the batteries in good condition and give a longer life span. Your scooter will be more reliable and not likely to run out of power.

The general advice is to charge your mobility scooter batteries after every use – but this is not strictly accurate because you may use the vehicle on more than one occasion during the day. For example, it would not be a good idea to charge it after a quick morning trip to the shop when you know you are going to use it again in the afternoon.
An important point to note is that you should not interrupt charging. In other words, be sure that the batteries are fully charged before you take them off charge. The best thing to do is charge the batteries overnight – as long as you have used the mobility scooter that day. There’s no harm in having your batteries fully charged and then using the mobility vehicle at a later time, but if you use your scooter every day, it’s quite simple – charge the batteries every night.

Only use the charger that has been supplied with your mobility scooter or powerchair. Using an incompatible battery charger is likely to be detrimental to battery life. If you lose your battery charger, be sure to replace it with one that’s approved or supplied by the vehicle’s manufacturer.
It will take around eight hours to charge your batteries to their full capacity, and while it’s impossible to disconnect them from the charger the moment they’re full, it’s important to not leave them connected unnecessarily. As soon as you know your batteries are fully charged, disconnect them. When you remove your mobility scooter from charging, firstly turn off the mains and then disconnect the charger from the vehicle.

Excess dampness can be harmful to all batteries – and mobility scooter batteries are no different in this respect. If your mobility scooter gets sodden with rainwater, it’s a good idea to remove the batteries and wipe them down with a dry cloth before placing back into the scooter.
Keeping the battery terminals greased will also contribute to a longer life. Use petroleum jelly for this, because many greasing products contain materials that conduct electricity or degrade plastic, or both.

Extreme temperatures can have a detrimental effect on the life of your mobility scooter batteries – so it’s important that you store them in a suitable place if you are not going to use the vehicle for a prolonged period. Leaving your scooter in a cold garage with the batteries in, for example, is not advisable. The best solution is to store your mobility scooter indoors, but not too close to a radiator. If that’s not possible, removed your fully-charged batteries and put them in a cool, dry place such as a cupboard.
