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...

Will the Trimetric come up with similar results if I can figure out
how to program it at another level, mine is L1 at the moment.It is a 2025.
Are all three measuring the capacity left in a battery that is not new?
Battery monitor will provide more-less accurate estimate for SOC only. Doesn't matter whether old or new battery. It simply counts amp-hours in and out after you've fully charged it and reset SOC to 100%.
To program the Trimetric, you need to install the shunt. Then follow the manual.
Looks like you've been using an expensive monitor as a simple volt meter that you could've bought for $10. Btw, I don't have battery monitor and don't feel like I need it - despite the fact that my batteries are AGM and therefore have no direct way of measuring SOC. Big solar, low loads, batteries are fully charged by noon or early afternoon.
