Amp hour meters need periodic re-zero-ing and with a sealed battery that means twirling knobs and poking a stick at the battery.

... That's why I'm not an amp hour meter fan. They're too complicated for us common folks, or alternatively, it takes too much time keeping them accurately representative of what state the battery really is in.

In keeping with K.I.S.S., I just use a simple voltmeter and a simple hardwired-in amp meter to keep an eye on the RV batteries.
