Just upgraded to 6 volt
I have two Trojan T105+ deep cycles that I replaced my old 12 volt boat batteries with. Series wired, off course. I suspect I'll have more amp hours now. Question; should I do any maintenance on t...

The ratio of under warranty batteries failing was something like 50 car jar 6 cells for every genuine Trojan T105. Or 50 to 12 for Us Battery GC220 3 cell units. All flooded batteries. Even the 6 cell Trojan car jars had an unacceptabally high warranty rate. I sneaked around from the counter (friend warrantying an Interstate battery at a distributor. I grinned at his warranty pallets. I got caught by the owner (open air loading dock) Threatened to call the Sonoma County sheriff. Probably less concerned about his wife and kids. Touchy touchy issue.
If you look at the trojan cycle life chart the 12V deep discharge batteries have much lower cycle life than the 6V, AND are recomended to not go below 50 percent SOC.
but they are better if you want to drive heavy inverter loads. first they have much lower internal resistance, second your usually sharing the load with twice as many 12V banks.
Lesson: determine what YOUR application is, and pick the battery configuration best suited to YOUR application. No ONE perfect solution for every application.
In my application cycle life, and deep discharges were top of the list, followed by occasion heavy inverter loads, 5 minutes or less. But that meant I needed 4 GC to satisfy the later. So that is whatI ended up with.
