Last golf cart question I promise

Does this fit your cart/charger and answers your question? Clicky.

I've done it both ways. One year, I had a fleet of 50 to service. They were new carts but the Golf Course had not thought through storage or charging so after service, off they went to bask in a MN Winter. All but about 3 moved the next Spring and I write that off to bad cart management during the previous season.

Since I've had solar and am able to baby a pair of these 6V's in storage, I'd say they do much better with constant attention and a daily charge. The best might not be one of those Lester chargers. I owned one, an old beast, and it really pushed the amps but wasn't very smart. Maybe their newer ones with the separate "storage" function works well?

I would fill the batteries, then fully charge the bank. Once done unhook the main negative, then the main positive (just to be double sure,) but leave the bank tied together.

The best answer really is to call your local EZ-Go dealer. I see you're in Florida, but getting forum info about cold conditions. :h


FWIW, I just did my Club Car this way today. I put it away for 5 months in the cold though.

Onboard or standalone charger? What make and model?

This newer 36V Lester charger has a separate "storage feature" (floats), otherwise it turns off.

This newer Onboard Lester charger has the same storage feature.

Many older chargers never turned off. Some turned off when the batteries reached a certain voltage set point sensed by the charger. If you have an older, unknow functionality charger, it would be best to monitor the charger to see what it does after the batteries are fully charged.

If you are messing around with golf cart chargers and batteries, you need a hand held multimeter. If you own an RV, you need a hand held meter. If you are alive and want to find out anything about the hundreds of electrical items you own, you need a hand held multimeter.

I have a 36V Easy Go,an older one, my factory charger does what yours does,pegs at 15 then drops off. It will not restart unless turned off then restarted. Look at yours and find the # and look it up, the newer ones go to float mode then back to charge. Yours may be one of these.

I replaced it with a smart charger like this one

I usually charge them before winter and check SG/water. Fully charged batteries should winter through some very cold temps. I have a 2008 EZ-Go but I've never left the factory charger on very long. No idea if they will re-detect voltage etc and re-start the charge cycle.

worth a look here -

Trojan batteries claim -92f before freezing

RTFM but I believe the chargers are smart chargers.

What I do not know is if they will restart without a unplug and re-plug.

Inherent loss of charge is incredibly temperature sensitive/dependent. Forty point zero volts is about right for floating a series 12-cell battery.

Depends on the charger. I think some of them just kick off and then won't restart unless you unplug and re-plug.

We've always just parked Mom's cart in the barn with the charger sitting on the platform in front of the seat. When spring comes, we drive the cart back out beside the garage and plug it in. Usually sits about 5 months through bitter sub-zero temps without charging.

If the batteries are fully charged when you park it, they will not lose much charge over the winter, and charged batteries don't seem to freeze.

Good question, I was wondering the same thing so I will be watching this post as well. thx
