I picked up a couple of second hand electric razor scooters with charging issues. The batteries would only charge for a few minutes then the fully charged light would come on the charger. I figured the batteries in the scooter ( 2 x 12v SLA) were needing replaced.
I replaced the 2 batteries in one of the scooters at the weekend with 2 new batteries, these new batteries are taking a charge, but one of them always charges at over 15v regardless of the terminals its connected to. I tried another new battery to see if one of the new batteries was faulty, but the same thing happens, one battery is always over charging.
Are both the chargers faulty? The output voltage on both chargers is just over 13v when its not attached to the scooter.
Cheers
