Do battery cutoffs and auto-reset breakers ...

...fail in such a way that they reduce battery capacity? I put a brand new battery in my rig but this morning 20 minutes of furnace dropped the voltage enough that the main circuit breaker tripped ...

The breaker was failing. The switch shows quite a bit of resistance. I'd suggest to spray some electronic cleaner into it. Caig Deoxit 5 in a spray can is what I use. It lubricates just a little but it removes corrosion.

Yes, your Grp 27 isn't going to provide much capacity even when new. Will it be enough for you, I don't know. I'd suggest to install 2 x GC2 6V as replacement. Their construction allows for longevity with RV use.

Good luck with the 12V, at least you got to inspect everything.:)
