Estimate how long it takes to move from one state of charge to another with a charger and any loads you leave running.

How it works
Multiply rated amp-hours by the difference between starting and target state of charge. Divide that amount by the effective charge current after subtracting loads.
What to check before you use the result
This is a constant-current estimate. Absorption, battery temperature, charger derating, and battery management limits can lengthen real charging time. Use the average battery-side load in amps.
