What is the purpose of having 4-6 volt batteries vs 2-12 volt? I assume it is due to the heavy current draw when starting a diesel.

The 6 volt golf cart batteries are designed to discharged/recharged. I don't know of any truly deep cycle 12 volt batteries even though there are a few labelled as such they're really dual purpose batteries.

Hi All,


Upon inspecting the batteries, I noticed the date stamp was from August of 2005. I guess I never really though about the date before. Is it possible the batteries are that old and still good but not keeping a good charge?


That is 14 years the LONGEST I have ever heard of Lead Acid batteries lasting was 12. and that was Exceptional life.. 7-10 is normal mine made it 9.


Home is where I park it.

The batteries charge faster on the generator or engine. We had new batteries installed in 2012. Going down the road with generator running the it took perhaps hundred miles for the batteries to show full charge on the panel. Older batteries might benefit from the desulfate setting. Read the manual on charge level and have battery compartment door open. However just getting them to full charge might be all that is needed. Check the level in the batteries too. We rarely use our battery bank, of flooded cell T105s. When we do it is by error. We left vent fan on for a month. They say to fully discharge our batteries sometimes, so we did that, and they were dry too. Filled up and charged they seem to be alright, but we will have them checked.

There are plenty of 12V deep discharge batteries. Almost all golf carts these days don't use 6v batteries anymore so they are either 12V or 8v. Trojan as well as many other manufacturers make them.
