Capacity Testing and 20 HR Rating
I'm thinking about doing a capacity test on my four GC2's. They have a 20hr rating of 215Ah. One thing I'm curious about is how the 20hr rating would have been determined. Being 6v, would they h...

Most flooded L/A batteries have an effective CEF of around .9
Meaning 110% more energy has to go back into the battery than what was withdrawn. There's a catch - at high amperage the CEF degrades meaning more energy "vigorish" is needed and the CEF percentages decrease.
A person does NOT have to be an engineer to enjoy the benefits of kWh relationships. Observation of energy transaction RELATIONSHIPS in and out is enough ammunition to feed Trends and Tendencies and mere intuition serves to provide a user with a wealth of information about what is happening with the chemistry of the battery. By corroboration with hydrometer reading, kWh values can open up a whole new world of understanding what a flooded battery is really up to - merely by comparing in and out energy transactions.
