1 of 6 batteries is dropping voltage

[19th hole]

Bought a used 2003 EZGO a couple weeks ago. It has bran new batteries from Costco. I’ve used it 4 or 5 times. It has a hard time making 18 holes with 2 adult riders. I test the batteries beforehand and they are all at around 6.3 volts. I tested today when I noticed it getting weak and they were all around 6.2 except 1 was a 5.1 with a little moisture on top. Could this be the reason it won’t make 18 holes. I was hoping to be able to get 36 holes. Thanks in advance

Yes.

Take a 6 volt charger and try to build that one battery back up to the rest of them. Don't use the cart charger it will boil the other batteries while building the one up. If you can't get the one battery charged change it out depending on how old they are.

Make sure you check the water level in that battery before next charge.
