Charger will not shut off

MarkK · 05-30-2018, 10:25 AM

I have a 1983 CC DS 36 volt electric cart that I replaced the 6 volt batteries in and now when I charge the cart the charger will not shut off. It kicks on immediately when I plug it into the cart even with the cart fully charged. I had the charger checked to make sure it wasn't the charger and it is not. Any suggestions as to what to check?

The first charge can be the longest. Especially if your batteries have sat on the shelf for some time since the acid was added as often happens. Not unusual to see the charge go 12 hours the first time then less and less on subsequent charges. 45-46 volts is the cut off for most 36v chargers. As long as the charge current is low 5 amps or less after 8 hours let it go until finished.

I had a new set go 22 hours one time, freaked me out but I was dancing around when it cut off.

Thanks for the quick answer. They have charged 8 hours and the volts are 39.4 total. I stopped them because all of them are boiling and I don't want to do anything I shouldnt Is it okay to continue letting them charge up to the 45 or so volts if they are all boiling? Not sure if it will hurt anything.

is it alright to let them boil continually? Will it hurt anything?

@2.4 volts/cell the voltage needs to get to 43.2v to be completely charged. Double check that one isn't in backwards . When you say boiling do you mean vigorously boiling or more like a simmer. What type of charger do you have?

They are not at a vigorous boil, more like a simmer but you can here them. It has a Ultra Power II charger.

No problem let it run. While you're waiting for it to charge read over the service manual.
