I've a 48 Volt Club car. I believe that one or more of the 6 batteries are going bad due to fully charging and then not being at full power. Does anyone know how to test each battery to determine which ones may be bad or going bad?

Fully charge the battery pack. Then disconnect one lead from each battery and use a load tester to test each battery.

If you don’t disconnect one lead from each battery before testing, it could give you an inaccurate and false reading

Fully charge them then take them out of series and test each one. See if a battery is below ~6.4v

Make sure to check out how old they are too. Sams sells some batteries that have worked great in mine.

I’m having the same issue in my 36V EZGO. I’ll charge it to a full charge, but the batteries will not last nearly as long as they did when we bought the cart.

Update: I stopped at the local Autozone and found a $5.00 Lynx Battery Hydrometer. I had to test each of the 4 cells on every one of the 6 batteries. The good news is 5 of the 6 batteries are still good, and only need to buy 1 replacement 8 volt battery at over $100 a battery.
