Since I added water to my 2002 gem car it charges but only

Customer Question

Since I added water to my 2002 gem car it charges but only for a short while the car will show it at 100 per cent but drops as soon as gem is driven down to 80. Once it's plugged in it charges but quickly the light goes from yellow to green . The sound
of the charger slows down but keeps going for a while even though the light is green my batteries are 4 months old. It is the four seater. The charger stays on a while when plugged in the charge light starts out red flashes once the goes green with charger
staying on. It does charge but you have to keep unplugging and rep lugging it in to get a charge .

Do not short cycle the charger! Run GEM down to 60 % , then plug in the charger and let it run until it shuts off. Do not plug and unplug it, it has to stay on , to put the full charge in batteries! Might take 8 hours!

Yes. I feel it has something to do with the charger it doesn't stay in the charge mode long enough. It used to charge for hours but now it doesn't. Battles are new

If the batteries are ok how do I determine if the charger is bad
Expert:  Curtis B. replied 1 year ago.
If batteries and cables are good, then the charger has to be bad.

Only by checking on another car!
