When should i recharge?
New to carts, just bought a 2010 txt, brand new batteries and i charged it when i first got it a few weeks ago. Full charge was 51.2. I am now down to 47.7 and confused from my research about when to recharge it. We only use it occassionally to cruise around the neighborhood. From what i have been able to see some say to charge it after every use, and some say don't do this as it will shorten the battery life. At what reading should i recharge?

Re: When should i recharge?
I try to not let my cart go below 49.5 volts before I recharge. DO NOT let it go beyond 48.4 volts (50% SOC) before a recharge. It will shorten your battery life considerably. Here is the rule I follow: If you drive it--charge it. Do not let it sit in a discharged state overnight--even slightly discharged. Who ever said that charging your pack after every use will shorten battery life is full of it!
Hope this helps Dave |

Re: When should i recharge?
onebadstang08.....once you got a full charge, the absolute best thing for your batteries is to maintain them as fully charged at all times as you can. WHEN you use your cart....as soon as you are done with it for the day, PLUG IT IN. If you don't use your cart during the week, reinitialize the charge cycle before the weekend arrives. That way you are good to go as far as it will take you that first day....

Re: When should i recharge?
While I agree with those who recommend charging after every use let me pose this question. I have a '13 RXV with the 4 12V US Batteries and a stock E-Z-GO charger. Reportedly, the US Batteries charging profile and the charger are not perfectly aligned. I have noted that charging after smaller uses/discharges produces somewhat less than a full charge (by SOC meter). However, sucking them down a bit more -- say 3/4 or a bit below and I get a more complete charge. Recommendations?

I do not believe it hurts batteries to slightly discharge them without recharging every once and a while. It may even help extend their life.

Re: When should i recharge?
I wanna post my newest SOC or state of charge chart for recommended use & recharge levels - this looks like a good place to land it.

Re: When should i recharge?
Nice chart scottyb - thanks for making that and posting it.
The explanations along the sides are good reminders too. I think I saw a note on the Trojan Battery site about letting batteries set for one hour after use to get a more accurate resting voltage. As opposed to the 12-24 hour rest after charging. |
