Golf cart battery life question

I sold my TT 4 years ago with 2- T-125Trojans batteries, still going strong after 10 years. It was a no brainer to buy 2 for our new to us TT. The thing with batteries is if you discharge them below 50% you shorten their life. I installed a Trimetric Battery Meter and that lets me know % of charge all the time. Its on the wall facing the door so when I open the door its visible. I also check the fluid level before and after every trip. We dry camp a lot and charge the batts with 428 watts of solar. So as soon as the sun comes up, there charging.

What Crabby is saying is true. GC batteries like other lead acid batteries should be used in their upper half of available amp hour. Going below 50 % will shorten the life of the battery. Recharging from 50% to 85% can happen quickly with the correct charging system. From 85% to 100% the battery tapers off slowly on how much current it will accept, so this phase of recharging can take many hours.

I created a spread sheet many years ago to boats that like to anchor out to help manage battery banks. Send me a PM with an email address if you what a copy that you can adjust to you battery bank amp hour capacity. Chris
