93 36v charge time
I am both new to this forum & to the golf cart community! I just purchased a 93 CC, 36v with a Lester charger. The batteries were new in 2009. It is plugged into a 30 Amp service in a trailer park.
I have charged it a couple times, but the amp meter on the charger never goes above 10, and eventually drops down to almost 0, but the charger does not shut off, the longest I have left it is 24 hours. The batteries seem to be recharging, although we are still trying to get a feel for how long they will last. (we have lots of hills!). There is a delay of a couple seconds before the charger kicks in, which I read was a good sign for the timer in the charger. The last time we charged it (the third time for us) the cart was almost dead. Even still, the meter on the charger never went above 10. My question is -- should I leave the charger on for more than 24 hours to see if it will shut off? Any other comments about this scenario would be most appreciated! Thanks for all the good information available in this forum, I look forward to being a good student!! |

Re: 93 36v charge time
welcome to BGW thats a kinda hard question to answer as every set of batteries is going to react to charging a lil different......my 1993 36 volt with 8 month old batteries if i start charging it at say 8 or 9 pm when i check it at 7 or 8 am is done and charger off and my amp gage rarly goes above 13 amps....more common for it to go to 10 amps..............if nothing is getting hot and your not boiling your bateries try charging it for 16 hours than shut it down for 5 minutes and start charging it again and see if charger turns off before another 16 hours..............also what kind of shape are your cables in?................................

Re: 93 36v charge time
OK, Thanks Tom, I will do just that. Other carts I know of charge in about 5 hours, so I was worried with the length of time.

Re: 93 36v charge time
It sounds to me like the charger may need repair. It should go to nearly 20 amps to start the first phase and then taper off in the next 2 phases of the recharge cycle. I does not sound like you are getting the proper algorithm ( charging sequence or pattern)
If you can borrow another charger and see what happens. That will tell you whether it is a cart or charger problem. |

Re: 93 36v charge time
Yes, they should always go through all 3 phases of the charge cycle. The 1st phase is the 'bulk recharging'. The rate of this charge cycle should be very close to 10% of the battery capacity. So 20 amps for a 200 AH battery. Each cycle is very important to proper maintenance of the battery. The cycles will just be shortened if the battery reaches the preset limits quickly.

Re: 93 36v charge time
Older chargers I would say maybe a diode problem and newer chargers a circuit or control board problem.
