Charger not turning off?
I have a totle charge III charger. it will turn on when you plug it in, but it's not turning off. The batteries are a year old. I've got the cover off and every thing looks ok. I put a meter on the dc cord, and it checks 44.8v, but it's not turning off.

Re: Charger not turning off?
You can't check your battery voltage with the charger on. You need to wait about an hour after the charger shuts off to get a good reading.
On the charger...you have one of 2 things going on. You either have a bad connection somewhere or your PC board inside the charger is bad. More than likely a connection. A simple test for the board....unplug the charger from AC and DC, now plug the charger into the cart and listen for a "click". That will be the relay inside the charger. If you hear that your charger is more than likely OK and you have a bad cable connection somewhere. Feel around on the cables and I bet there are a few that are warm..... The worst case is the batteries are toast. |

Re: Charger not turning off?
More questions:
How many hours did charger run? What does/did ammeter read? The 44.8 is a bit low on the finish side of a charge cycle IMO. Mine gets to ~45.5v and ammeter is at ~2A at finish. A highly discharged 36v pack can take 12-14 hours to complete a cycle. FWIW & HIH |

Re: Charger not turning off?
I Charged them about 10 hours. The amp meter was at 5, when I unpluged it. I will charge it again tomarrow, and see if my cable is heating up.

Re: Charger not turning off?
You wouldn't think that 1 yr old batteries are suspect but it might be a good idea to check the SG of each cell.

Re: Charger not turning off?
Yes, pgproves, It has been known to happen. For all you that are not rocket scientists; SG means specific gravity. A simple $7 hydrometer from the auto parts store measures the specific gravity of each cell to determine the amount of activity or health of the cell. It is a very good way to judge the state of a battery..
