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 ...

I guess the word HYDROMETER is like saying Wife Beater or Child Molester. Not spoken in polite company. Reaching 1% or .5% with a flooded battery is worthless without the time factor being a component. FLA is not AGM. By trial configuring a dedicated formula for your own bank is a possibility. Exchange 3 hours to reach 1% with 8 hours to reach 1% and the factoring estimate becomes moot. This is a chemical engineering subject not a pure E=MC2 math equation. Trends & Tendencies must be calibrated via a hydrometer, clock, voltage and amperage. Something an integrated circuit is sadly lacking. For what must be the hundredth time on this forum THE HYDROMETER READINGS ARE REALITY YOU CAN SEE. Once you lasso an idea of instrument behavior to "reality" then instrument management is possible but aging skews trends and tendencies so periodic hydrometer readings and readjustments are not an option. Hope this helps.
Heh, should've expected that. Don't doubt that you are correct: Constantly monitor your FLA batteries with a hydrometer and devise the best charging regime on the basis of that. Good advice as always. Thanks.
But ...
Hydrometers. Gawd I hate hydrometers and battery acid and acid holes in my pants. Should've got AGMs for that reason alone I suppose.
And batteries, as a long-term object of study? Not knocking you and the other dedicated experts on this forum, but I can think of maybe a million things I would rather be doing.
So, yes, I'm just looking for some free advice that doesn't require me doing much of anything except tweak a parameter or two on my solar charger.
EDIT: See don_a understands.
