Battery Replacement
I have a 2005 Club Car Precedent that came with four 12 volt Trogen T-1275 batteries with a 150 amp hour rating. Not even sure these are the right batteries for this type of cart. I checked all 4 batteries and the readings are , 12.47V, 12.27V, 12.28V and 10.35V after a recent charge. Looks like one of them definitely needs to be replaced. I do need a recommendation on brand replacement, especially on the amp hour rating. Is 150 amp hours marginal for this cart?
Thanks |

Re: Battery Replacement
Your note should read "batteries replacement". As long as you don't require the cart to go miles and miles and miles between charges, the Trojan T1275 (they were original equipment in that year) are considered very good batteries.
Here's the down side - if you replace just one in an old battery pack - it will be as-bad-as the old ones (however bad they might be) VERY QUICKLY. When wired in series, which golf cars are, the batteries are like potato chips. You can't have just one! The single replacement battery will decay almost immediately. Assuming the cart has served your requirements well so far, the Trojan T1275 are excellent quality replacements. The trouble is, you will have to buy four to get any long term life from your pack. |

Re: Battery Replacement
Having one bad 12v battery out of four is almost always the result of tapping that battery for accessories, make sure you get a 48v->12v reducer for your cart.

Re: Battery Replacement
Albeit not the preferred method, when I have had one (1) bad battery in a set (yes, it happens from time to time) that was not very old or still had plenty of life left, I would find a similar battery of age and amp-hour and replace it until I needed a new pack. Has worked many times for us over the years, BUT, my point was more so that we did that with a "good" pack. You should be getting ~12.73 volts 12 hours after you charged. Your number are far below that which is a tell-tale sign that the pack is going out....
See the attached for a State Of Charge (SOC) chart. |

Re: Battery Replacement
Forgot to post about this in my last post. Has anyone added 4 digital battery voltage meters to their cart to then actually see, in real time, the batteries voltage. On my last cart I did install one digital meter and it showed the pack voltage which I liked because it told me the state of my batteries and when it was time for a charge.

Re: Battery Replacement
You can connect all of the batteries together in parallel (not connected to the cart).
Leave them that way for 24 hours. All voltages will balance. Then reconnect them in series. Charge them as normal. Check each battery’s voltage. They should be the same. Sent from my iPhone using Tapatalk Pro |

Re: Battery Replacement
Same voltage does not mean same remaining capacity, if this was related to a single discharging event, simply connecting a 12v charger to that battery would fix the problem.

Re: Battery Replacement
As Sergio stated, and with a 10.35 volt battery, that is a cell issue and will not ever balance out.
In regards to batteries, US Battery, Trojan, and Crown's are the top line for carts. For normal social riding and venturing, my last set of US "Red Tops" made it 10 years with correct maintenance and charging. Although this is rare and that cart was not used for hours and hours everyday, they were great and lasted right up till the end with still be capable of holding 50.x volts 12 hours after charging. When they went out, it was literally all at once..... |
