batteries keep charging

[yellow57]

The 8 volt batteries in my club cart will not stop charging. The charger will continue to charge for hours to the point the the batteries get warm. I know it's not the charger because I have two carts and the same thing happens with both chargers.

batteries can charge up to 16 hrs .. warm , bubbles are normal

I've noticed when the out side temperature reached 70 my batteries went charge hungry. They charged for 16 hours, two cycles in a row. After that they charged like normal. If your cells are low on water they will charge for a long time as well.

Also, if you have a bad battery, the charger will just keep running and running. I just went thru this, tried 2 chargers like you, and would never shut off.

Ended up 2 batteries were bad.

How do you determine if you have a bad battery?

With one of these.....

The cart is a better load tester than you can buy in a handheld devise. Install a digital battery or connect a handheld voltmeter to the pack and accelerate hard ( uphill if available ). Your pack voltage should not drop by more than 5-6v collectively.

Check the voltage on all the batteries and compare the readings. Anything 1-2v low has definitely got a bad cell.

Thanks Scotty. I have a pretty steep driveway, so I'll try that today. Also, I know these batteries can take a long time to charge depending on many things. Last night for example at 1 am I checked the pack voltage while they were charging and it was at 43.5v and the old manual lister charger was at 7 amps. I checked the pack voltage just now while still charging at it was 43.7 and the charger showing 6 amps. It's been on the charger almost 18 hours now.......

That didn't work on my old cart that had "marginal" batteries .....they would all show pretty close voltage but some would drop WAY lower than others when I would put the load tester on them , then I would go to the "battery pile" with the load tester and find one that didn't drop so far.....plus the load tester shows volts anyway dosent it?

Krashole, The first guy that started this thread, said he had 8 volt batteries. At some point when you jumped in, you mentioned 43 volts.

If you have 8 volt batteries, and you are reading 43 volts, at any time, there is a problem. I think you are going to find a bad battery or more than one.
