AGM OR LEAD BATTERY (1 Viewer)

Test is more or less finished but my maths do not make sense.
After resting the battery for one hour it measured 12.56 Volts. I have taken 23 Amps out of the battery leaving 77 Amps (100 AH Battery)
So! 90/77 x 100 = 116 ?
But if I do this 77/90 x 100 = 85.5 This would indicate I have used 14.5 % of my total battery capacity which I think makes sense !
Very happy with that, if it is correct ? I will measure again after two hours resting.

Looking at a battery percentage chart that would indicate you have between 80 and 90% remaing, depending on battery type.

Yes Chris! I estimate 90%. My final voltage reading took just now was 12.57 V.
