My Screwy 31
First off let me say I am not stressing over this. It's just a battery, it is only money, it is meeting my overnight needs, but it is displaying strange behavior, and I am curious as to why. So th...

That 6 amps was going into the 31. The Solar was making close to 9 at the time..
US battery is specifying 14.4 to 14.7 absorption and the 15.3v finish on two of their 3 recommended profiles. I'm keeping it at 14.4 for now, cause it is easier for the solar to hold 14.4 initially, when the compressor kicks on, compared to 14.7.

I have not used my inverter for a few weeks now. My laptop charger is a DC to DC "car adapter" I have not used an inverter to charge a laptop in several years. I can certainly adjust when and how I use and recharge the laptop, but mostly it falls into the whenever convenient category, or if the charging cord gets annoying.
Right now 1.2 amps are flowing into the 31 to hold 15.3v and it will be at or somewhere near 15.3v till the sun gets lower in the sky( at least 3 more hours).
My Solar is producing 5.3 amps to power fans, light, this laptop and send that 1.2 amps into the 31, and add another ~2.5 amps when the compressor cycles on.
I'll be keeping these voltage setpoints for a week and check SG on Sunday if the Sun and my overnight usage allows a full charge to occur. I figure one cycle is not enough to see the effect of any given regimen so I will do between 6 and 8 cycles to get a better Idea how it responds.
