AGM Battery Capacity?
I want to measure the capacity of AGM batteries, I have monitoring equipment in my camper, Trimetric monitor. However that only reads the voltage as my solar charges the system and then as the vo...

Capacity test.
Divide listed amp hour rate of battery bank by 20.
A 100 AH battery can power a 5 amp load for 20 hours before voltage drops to 10.5v.
This is why I don't recommend the OP doing it. He needs to understand what he is doing, and how. The battery is AGM. Those typically have higher voltage at any given SOC. Trying to discharge it down to 50% - following the chart for regular wet battery - you will discharge it much deeper.
The result - incorrect estimates for capacity, and potentially damaged battery.
