New Batteries?

[JGC403]

I fully charged up the batteries and they have been sitting for almost 24 hours.

Checking the volts on each battery:
6.25
6.23
6.15
6.31
6.30
6.31

These are US 1800 XC batteries. There is a 4 stamped on one terminal and a E 3 Z stamped on the other terminal.

3 of them should be replaced. If I'm replacing that many should I just replace them all?

Yeah if you're replacing 3 you are better off getting all new batteries

I bought 2 batteries every month to ease the pain/cost, it worked out well for me.
I charge after every use and keep it trickle charging when sitting to try and maintain the batteries.

Also depends on how much you plan on using the cart but those levels give you a 37.55 volt state of charge after full charge

If you put in a in dash led digital volt meter like what carts unlimited has you can drive around until voltage drops to about 36.3

If you need to use the cart for only a few miles at a time, really depends on terrain, wheel/tire set up and distance and the ability to plug into the charger any and every time you arent using it, you might get some more life out of them which could buy you time to slowly save up and ease the cost pain.
