Battleborn 12 volt 100 ah battery, used 0.22 Kwh in 24 hours = how many ah were used?
I come up with 18.33 ah is this correct?

100 amp hours * 12.8 nominal volts = 1280 watt hours.
1280 watt hours / 220 watt hours = 5.818181818
100 amp hours / 5.818181818 = 17.187500001 amp hours
 
I believe both could be correct depending on the battery voltage.
12.8 volts * $ amp hours is the value that corresponds to the total capacity of the battery in watt hours.
I would be surprised if you don't know this.
 
This jives then, battery has used 18.33 ah of 100 ah yet is showing it has used 60% of capacity or 13.16 volts down from 14.1 in 24 hours.
