Managing Flooded Batteries Without Using Specific Gravity?

This is precisely why "meter managing" is impossible. If flooded batteries were pure Pb (lead) it would be simpler. But they're not, and it isn't. To my great regret I understand the formulas even though many of them are hypothetical baseline. How can they be hypothetical? When plate alloy is changed or paste density is altered the factorials must be likewise adjusted. Then readjusted for aging.

Throw your hydrometer a kiss. Like playing high-stakes poker with your personal marked cards.
