"Battery Pack Capacity is the battery state of charge"
The state of charge is a percentage of whatever the capacity is. The capacity could be anything.
You seemed to understand that earlier on:
"If I didn't fulltime I would break the cells down for a capacity test after 4 years now but not possible seeing they are my power source and I boondock all the time but some day maybe if I come off the road"
But you keep saying things like "capacity at 99%". You have to be able to answer the question,"99% of what?"
That is the problem with battery monitors giving percentage SOC read-outs. People first have to enter the battery capacity (size of bank in AH) and they fail to keep that entry up to date, while they keep believing that % SOC number on their monitors.
Same as saying "full". How much is full? With an AGM, full at 32F is 85% of what it is at 77F. The battery monitor doesn't know what the temperature is and adjust the capacity entry.
