Amp hour meters have to be "zeroed" occasionally or they become worse than useless.
I lost track decades ago of the number of people who complained...
"The batteries were full tip-top last night then at four AM the heater quit. There's a short!"
A battery charged to 12.75 volts resting may have half the capacity it used to. I wish folks would understand this. Trends and tendencies volt and amp wise with a real amp-hour meter is very handy. Danged tough to stare at a battery and psyche it into coughing up it's amp hour capacity. .It can be done only one way and you know what that way is...
Panel meters are useful to detect delivery anomolies. And that is it.
