Added a new battery monitor...(Aili)
Battery Monitor == Fun! Plus: How to avoid a common mistake regarding AH total I have a couple 2015 Thor Majestic 28a RVs. I added a 2nd 12v battery to the coach (they only came with one). My ba...

"Depending on the monitor" is the key there! On my Trimetric, the AH counter keeps climbing (auto reset is disabled so it can work with solar--otherwise it resets the AH counter every time it gets dark)
So it goes from say - 100 to about +15AH for a 115 return to actual full as seen with an hydrometer.
The way the Tri is designed to work (I don't do it that way) you need to enter your battery capacity in AH, then the AH counter can tell what percentage of that you have recharged to and it displays the %. If your capacity entry is wrong, so is the % and when it thinks it is to 100% and resets the counter automatically to zero.
I find that all so bogus, but that is just me I guess. Capacity on an AGM goes down with temperature by 15% from 77F to 32F, for one little thing. :( So there gores your capacity entry accuracy.
That method Mr Wiz describes for another model of monitor shows how you need to know what exactly yours does so you are not misled by it.
Been folks here who can't understand why their battery is nearly dead when their monitor says it is at 95%. They never got the battery full and only reset the counter to zero then, would be one thing.
