Mobility Batteries a Begginers Guide.

AGM or GEL ??? by Eric Roberts

In general there are a few simple things to consider when replacing your old mobility batteries . The first good piece of advice is to write down all the information that you can from your old battery. If you happen to be visually impaired, then ask a friend with good eye site to read the battery label for you. It is easy to give the wrong information and perhaps buy the wrong battery causing stress to all parties concerned the buyer and the seller.

Mobility batteries are what they say they , they are made to drive vehicles used for people with disabilities or to help the elderly person become more mobile. They are usually in the form of the scooter or much larger machines, using many mechanical aided instruments on board to aid disabled in things like steering and navigation in their wheelchair or scooter.

Mobility batteries come in two main types, GELand AGM, both are a type of sealed lead acid (SLA).The GEL battery has GEL granules added to the acid to form a solid structure that will not leak if the battery casing is accidentally broken, because of GEL the battery needs to be charged on a GEL charger at a constant rate of charge, chargers usually come with their own charging system so it should be difficult to get things wrong. AGM batteries are lead acid batteries with Absorbed Glass Matting added to soak the free flowing acid up, so once again the battery will not leak acid if the casing is broken. The AGM battery is charged in a different way to Gel the battery takes the charge as it needs it, similar to a car battery, therefore a different type of charger is required.

a new 34amp mobility batteries

To keep this simple my best advice is to stick to the exact same type that you have on now, the battery say on it what type it is either GEL or AGM. This also applies to the Amps if you have two 34 amp batteries on your scooter you should stick to the same. The only difference in the number of amps is that one maker may call a 33amp a 34 amp the shape of the batteries should be the same, any doubts just check the measurements of your old mobility batteries with your new mobility batteries.
