Over charging Batteries
2016 Precedent, Sept 2020 T875 Batteries, Club Car Delta Q charger.
Set up charger yesterday afternoon about 4 PM, got the 3 beeps and left it charging. At 11 last night I could smell a strong odor in Garage, charger still showing just the bottom lights, no fast blinking top light. Unplugged charger and checked Water level in all Batteries. Completely dry. Each Battery took about 40 ounces of water to just cover the plates properly. Pack Voltage was 51.9. This morning drove the cart for a couple of minutes then checking the volage at 51.2. Questions, 1. Do I need a new charger? 2 Have read several posts about profiling the Batteries, What does that mean?/ how would one go about that? The Batteries were installed by a Dealer and all have the same date code. They were installed in the cart in September 2020. |

Re: Over charging Batteries
What brand of batteries did the dealer install? Good chance you may need to update the charge profile.

Re: Over charging Batteries
did you check the battery level lately? my 03 will typically go 16 hours before turning off, so i doubt your batteries went dry on a single charge. for them to all need 40oz water each, you'd have to not checked the level since sept 2020

Re: Over charging Batteries
Have to admit I screwed up and it has been a while since I did check the levels. Also pretty certain all the water didn't go away this time, however, my questions really relate to why the charger was still going when the Batteries were fully charged. In the past, since new, I charged the Batteries until the lights stayed steady. That was what I had been told to do.

Re: Over charging Batteries
Most chargers do overcharge on purpose. IT's not bad for the batteries and it helps keep them balanced. They will gas and bubble when this is happening. Always check water levels before charging. Do NOT fill before charging unless plates are exposed. If they are exposed just cover them. Then fill properly after charging - because the level will rise during charging and it will create a mess if it's overfilled.

Re: Over charging Batteries
Thanks so much for the information. I will make it a habit to check the levels.
I do like to keep the cart on charge when not in use but am afraid to do that right now. Will be watching these Batteries to see how much damage I have caused. Looks like the cost of them has almost doubled since I had these installed. Again, thanks all. |

Re: Over charging Batteries
Charging to 95% is the easy part, the last 5% takes a while
Same with your cell phone battery, last 5% takes longer than the first bit |

Re: Over charging Batteries
You need to update the battery algorithm in the charger when using anything other than the factory original batteries. The factory setting for the ERIC charger will boil Trojan batteries to death.
You need to update to algorithm #3 from Delta Q website if you have not done so already. See here: https://www.buggiesgonewild.com/show...9&postcount=11 From Original post: https://www.buggiesgonewild.com/showthread.php?t=136229 And while you may still get some use out of them, those batteries will never be quite the same. When the plates go dry it causes permanent irreversible damage to the plates which cause a loss of capacity. If you only use the cart for short trips, a mile or two every few days, then they'll likely suit your needs for quite some time. But if you need to use it for longer distances like a couple miles to the golf course and then a full round and then back to the house, they probably will let you down. |
