Golf Cart Question...

I'm stumped. I have an older cart that I've had for two years, but only took it out about 4 times. Now the grand kids want it so I am trying to get it ready. Batteries (T-50)are of an unknown age and went all the way down over this last year. I have now charged each separately and 5 of the 6 show 6.78v and #6 is at 5.55. I then connected the cart charger and all seems good.... 35.43v and it actually moved forward and back, and then very very slowly forward about 30 feet and won't go any further. Stepping on the pedal it tries to move but lacks enough power. I plugged it in again and after it was charged again it moved about 75 feet then again no power to move. I recharged it and let it set over night.... The 5 batteries are reading 6.67 and the 6th is at 5.25v....Is this 1 battery causing the problem or is it more serious? should I spend $500+ for 6 batteries?

Your input please....

Thank you for your time and thoughts...

    Replace them all,one bad one will do what others have said.

    I replaced all 6 on my cart with the Sams brand and they have been in use for about 4 years now with no problem. Oh and yea the Grand Kids do love to run it a lot, they charge up easily and hold the charge.
    They seem to work as well as the Trojans that they replaced and at a much lower cost.

    Hello back and thanks so far. It has 6 batteries, its a 36v system.

    yrusoslo ...It has 6 batteries, its a 36v system....I saw some Golf Cart Batteries at Sam's Club on Saturday, they were $84.** each, do you think that beats NAPA? and does it make a difference on which batteries I get as long as they are 6v?

    If a cart has 6 batteries, its a 36 v system

    A 6v battery does not read 8v, except under a very hi voltage rate of charging

    ps ALL CARTS HAVE A 48 VOLT SYSTEM SO YOUR 6 BATTERIES AT A FULL CHARGE SHOULD BE CLOSE TO 8 VOLTS APIECE

    IMHO. Equalize weak battery no 6.

    Ten amp charge rate on one bad battery.

    Leave charging until battery reaches 8-volts. Disconnect

    Next morning check voltage on battery. Should read 6.3 - 6.4

    Try it in the golf car. If it works, you're finished.

    Hello, I work at a golf course as a mechanic. yes one bad battery can bring down the needed voltage. the proper way is to put a load test on each battery and see what the voltage drops is. With that, I would say that a new set of batteries is your best bet. Do check all of your terminal connections, this also can cause problems. I buy my batteries from NAPA, they are a little cheaper than going to a golf cart store. Good Luck
