I believe you have it backwards. As far as I know, 100% of the AH gets stored in the battery, while perhaps 90% of WH goes in battery. The battery is fully charged at 12.8V, yet we're charging at 14.8V. Where are those 2 extra volts going? This is lost power that goes to heat. It's the cost of charging a battery. That's why WH is meaningless when you what to know how much you put into the battery.
