Charging Problem
Hi! I am new to electric carting. Just bought a 48v Club Car. I couldn't get the charger to work so I bought a new one.
Dumb!!! I then read that the batteries have to have a certain amount of charge to get the charger to kick on. My question is how much of a charge do the batteries need? I have 6- 8V Trojan PowerDrive batteries. The individual baterry volts are: 3.59 3.18 4.25 5.29 4.20 2.43 Thanks for any help anyone can give!!! |

Re: Charging Problem
From Trojan Battery Website:
State of charge as related to specific gravity and open circuit voltage Percentage of Charge, Specific Gravity Corrected to 80o F, Open-Circuit Voltage 8V Battery 100% 8.49, 90% 8.41, 80% 8.33, 70% 8.25, 60% 8.16, 50% 8.07, 40% 7.97, 30% 7.88, 20% 7.77, 10% 7.67 It sounds like it's time for some new batteries! Trojan recommends to take your batteries down to no more then 50% to maximize their life and no more then 20% at any one time. Your batteries are far past that at this time. |

Re: Charging Problem
You could try disconnecting the battery pack and individually charging the 8v batteries with a 20a 12v automotive charger for about an hour each to give them a little kick in the pants. Then measure the voltage on each battery, if they are close to chargeable, reinstall in the cart and see if the charger brings them up to charged status.

Re: Charging Problem
Thanks guys! I know I'll need new batteries soon either way. I just can't afford them right now. I'll try charging them individually to see if I can get by for a little while.
What voltage do I need for the charger to kick on? Thanks |

Re: Charging Problem
I don't have info on the charger and someone with knowledge can add comments but I would think all the batteries would have to be at least 7.5 volts each before they will take a charge.

Re: Charging Problem
Hello All, I'm having the same problem with my 48v. My batteries were not as low. 7.77 was the lowest one.
At what voltage do you think the charger will kick back on to begin charging? Should I get all my bats to at least 8.15 or higher. Thanks for any help. John |

Re: Charging Problem
Thanks for all the help!
I replaced all the batteries and now I have a new problem. I hooked up all the batteries and the cart still wont go. The headlights come on and if I plug the charger in it kicks on. I do hear a click when I hit the gas pedal. Could it be a wiring problem? Thanks for any help! |
