I tried that, it was painful so I stopped. Do you see spots too?
I’m needing a new lead battery for my solar as I might be selling my lithium batteries. Buying a motorcycle and working on the roof takes precedence. Do you recommend the Napa battery?

Moving away from lithium to lead. Anarchy. Cats sleeping with dogs kind of stuff.
I have a holey roof that I have to make unholey. Reverse exorcism. Eternal bonds to bind the roof.

East penn make a pretty good flooded marine battery.
but it is still a marine battery, not true deep cycle.
When needing 200+ Ah of capacity and not requiring powering large draw items like inverters powering coffee pots/microwaves, the golf cart gc-2 batteries are far superior in cycling durability.
Morning voltage is a good indicator, on a specific battery, compared to itself.
Batteries intended for northern climates will have higher specific gravity than those for southern. Higher specific gravity means higher voltage retention/ more CCA. The stronger acid eats the plates faster though.
So if max voltage retention by morning alone were the only benchmark one cared about as a performance indicator, then the flooded battery designed for Far north Canada would appear to be far superior than the one intended for the tropics. Yet the one for the tropics would outcycle the other all factors being equal, it would just have lower morning voltage and appear to be weaker.
Does EP change their electrolyte strength for batteries intended for northern/southern climates?
I'd hope so but expect not.
6v Golf cart batteries in series might not seem to perform as well as a pair of 12v marine batteries in parallel, in the voltage retention department, but with equal treatment, the GC-2 batteries will accumulate 2 to 3x more total cycles

Speaking of GC2 batteries, the batteries I’m salvaging tomorrow are Trojan T105’s. Supposedly there’s 4 that have some health left. And 8-10 that are dead for scrapping. It’s going to be a lot of weight in my van.

which is more important,shortest solar panel wiring or being able to check your charge controller easily?
i have no walls,just windows,to put a charge controller in a cupboard would increase the wire length 8 or so feet,a direct route would put my charge controller in the battery box and i would have to go outside and open the door to check it

My opinion is............
Compromise , put it in the cabinet and run bigger ga wire from the battery.
If it won't fit into the controller ,
run it anyway and butt connector it to a piece of the biggest wire the controller will accept right at the controller...
I buy up to 6 ga connectors at Advance Professional/Carquest but they probably have bigger !
stay tuned
