Battery Voltage Discrepancies ??

The only problem that I see is the one that arises when you do successive 50-90% charges without topping.

Like I said, they get a daily charge to something close to 100% SOC. In daily cycling I'm typically in the 90-100% range, at least according to the TriMetric. Alas, I have not "topped" them above 14.7 (at least not until today).

So what kind of inverter use are you employing that takes advantage of the high current capabilities of AGMs?

I have a ProSine inverter/charger. It's rated at 2000W cont' and 4500W surge (up to 5 sec). I use it a lot (I hate generators) and my setup effortlessly runs the microwave and even the A/C for short stints. The charger is rated at 100A, but when the batteries were deeply discharged I have measured charge rates as high as 110A.

Oh and I love (using) parentheses too... so you can't intimidate me one bit with your (meager attempt) to over-use them ;)

Have you read the stated accuracy for your meter? Often it is stated as % plus or minus a couple of counts.

My Datel panel meter has a claimed accuracy of ±0.01V and I have calibrated it against my two Fluke 88's (both with recent calibration cert's). It is more than accurate enough for the task it is assigned to, especially since I'm interested in the deltas and not absolute values.

If the batteries are in parallel and not connected to an exterior load, if there is truly a voltage difference...

The voltage difference I noticed was with the batteries disconnected from each other & from all other loads... and after resting for 24 hrs.
