When the battery spec provides an ampere hour capacity, does that mean until the battery voltage reaches 10.5V? The various websites specify that voltage for reserve capacity, but nowhere can I find the definition of ampere hour capacity.

All the voltage vs capacity charts assume that there is no load on the batteries and that there is no surface charge. My coach with a few lights on, the inverter and fridge on, and the electronics on standby draws about 20A. Do you have any idea how that will affect the voltage measured?
