Batteries losing charge

[new england 2]

I have a 2002 remanufactured Club Car purchased in 2006. I had the current batteries installed in April 2012. I have had problems with them since Dec. They lose the charge. The company we purchased them from stated that 2 of the batteries do not charge completely and we need a converter for $213. They said this has been a problem on some of the Club Cars. Does this sound legitimate? I don't know if the batteries are the problem or there could be another problem.

If you had a remand golf cart built and they did not supply you with a 48-12 volt voltage reducer you could have that type of condition.
Your cart was most likely originally built with a 16-12 volt reducer.This design draws of only two batteries for all the items on the cart that use 12 volts.
The two batteries that are used are typically run lower then the rest in the bank of batteries
And therefore run behind in the charging process and after a years use can cause an inadequate charge to all six batteries.
On all our remands that we build we always use a correctly installed voltage reducer to avoid the type of problem you are having. These days most good cart MFG's include them as a norm.

Frank.... thanks for that explanation...first time I've heard it put so clearly.

I have an 03 Club Cart, reman in 06 by the now defunct Golf Cart Connection. I just got my 3rd set of batteries in about 6.5 yrs of use. I do use it a lot ...about 100 miles a week. I have always had initial problems with the 2nd battery behind the driver seat...so, my symptoms sound similar to OP and your diagnosis.

I have a voltage tester and "high end" hydrometer. 2 batteries had one bad cell each but the other 4 tested beautifully. Given they were 2.5 yrs old I elected to replace all of them (Trojan T-875).

How much do you charge for the voltage reducer? Might be a good investment now with a new set of batteries to make sure they last equally.

Thanks to OP and Frank for bringing this up.

Pricing on voltage reducers depends on the unit we install. It all depends on the accessories in use. The amperage ranges from 18 too 30 amps. Units range from $125 to $ 165 plus $50 install fee.
Also a note on the new Trogen Ranger Batteries we have been installing. They are boasting a 35% increase in Range over T 875, we are expecting to get a similar range as if we had 8 six volts in a 6 -8 volt cart.

Thanks for the compliment.

How do these Ranger Batteries price out compared to the T875 or T890s?
