36V Club Car power

[mikeb33]

My friend has an 89 Club Car DS 36V. 3 of the 6V batteries were about 5 years old and the others even older. It could run long on a charge and barely made it up hills. Today we put in 6 new batteries. I checked and they all were 6.3v. When all done went for a drive. It seems to have more oopmh from a stop, but on hills it slowed to nearly the same crawl as before. We went back and plugged it into the charger.
It has what looked like 6 gauge cables and we cleaned the terminals and they looked fine.

Question is should they need charging to perform properly if they are 6.3V?
Is there something else that could be responsible?

6.3 is 90% charge.

Shouldn't 90% charge perform strong enough to climb a mild hill without slowing to 5 mph?

This cart is so old it has no speed electronic controller, just some resistor coils behind the battery tray. Do these wear out?

Stock series drive carts will slow considerably going uphill- it's just the way they are. The coils don't wear out, so you're okay there.

Brand new batteries are not at full strength- they need to be properly broken in. See the link below for details. Once they're broken in, you will notice an increase in both runtime and power.

those carts just don't have much uphill......make sure the vglide (wiper switch ) is going all the way to the top pad but that's about it....

There’s a possibility of having a bad brush in the motor also. At that age they probably should to be changed.

Hard to do? Any tutorials here?

There are some threads on brush replacement, you just have to search.

The worst part is taking the motor off... some are a bear. There are threads for that too. Best to take the rear out and bolt a wood block to the wheel studs so you can drop the rear end on the block and shock the motor free...

After the motor is off. You remove the bolts that run through it so you can take the rear cover off and replace the brushes.
