Batteries for mobility scooters.

Danny1931

Scooter batteries are very expensive so the tendency is to look for the cheapest. You are warned that this is not the best policy. But I have never had a failed battery, they all lasted three or more years and I think they all originated in China. I am looking for two 12v.50ah batteries. What experience have others had on battery life ? .

Three years is about the expected life of a lead acid battery in this sort of application.

The CHARGER and charging regime has a great influence on battery life. I killed two sets of MK branded batteries on swmbo's Pride GoGo scooter (2x 17/18Ah batteries) by following the advice of the shop and manufacturer to charge after every use and overnight. This despite the claim the charger was 'intelligent'.

Now, I charge until the green light comes on saying 'charged' and take off soon afterwards. The third set are now in month 38 and on charge number 223 and still going strong. We don't even charge after every use any more, only if we know want a longer range 'tomorrow'. BTW using the same charger, just different batteries (Lucas branded). I'm convinced the charger was cooking the batteries overnight, leading to loss of capacity very quickly.
