Costco GC2 spec
I decided to replace the old GC2 batteries (4 years old). Costco's GC2's are now labeled Interstate Batteries. There isn't much data on the battery, just RC = 107. A "real" Interstate battery that ...

Rough road here for a guy just trying to get his batteries charged LOL ...

Well I am a closet techie and could do the work, saying this only because I am now down to seeking out instruction on converting surplus computer equipment since a normal variable voltage supply at 60 or more amps is extremely expensive I just found out. This build your own idea is in contrast to all the $500 plus lab supplies I just found on Amazon/eBay. So I was thinking since I am going to all this trouble anyway, why not just give the bats all they will take and disconnect the battery from the house lights during the "boost" charging process (since the normal power supply will be running the house equipment while the generator will be churning away). If I use one of those battery disconnect relays like already used in most coaches it means no power must be supplied to keep the relay engaged while the charging is idle, just a flip flop toggle during boost charging alone, and that would eliminate the danger of going too high with the voltage on the electronics while boost charging, plus mean that the coil of a normal solenoid would not need to be energized during daily use of the battery with all charging sources idle. I could also put a cheap temperature probe on one or more terminals maybe with an alarm if one of them got too hot. Ideally the alarm would shut down the boost or simply notify since I am charging manually. (Anyone familiar with this? Is 212F an indicator of boiling acid???? Surely lower???)
I found a disconnect relay online for around $60 and if I can build the surplus supply for a hundred or a little over, it's still a lot cheaper than the so-called smart charging equipment available commercially for the RV. And I say this only because what is being said here is the 14.8 like that's deliverable from the 9280C is still not as aggressive as can be dared in a manual setup (as per my understanding).
