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...

Just checked SG after the amperage required to hold 14.6v fell below 1 amp and amp hour counter said 1 A/h from full.
1.250 on all 3 easily checkable cells.
The regimen for the last 2 weeks has been 14.6 absV and 14.7 float/finish, and enough sun and time to get them to the float/finish stage every day. Mostly before 1pm. Often before 11 am.
No schumacher. A few mornings of short lived 50+ amps from the alternator.
Just switched all loads to AGM battery. Changed solar acceptance and float to 15.9v. 6+ amps were required to bring voltage to 15.9v. Now 5 minutes later 4.2 amps to hold 15.9v.
Max overnight amp hours removed since last report( 2 weeks ago) have averaged about 25 with a max of 35 and a minimum of 12.
Battery seems to level off at 12.2 volts under various loads around 11pm. I've not been checking rebound voltage with all loads removed.
Edit: 1.5 hours later, SG is 1.270 on all 3 cells. 15.9 volts, taking 4.2 amps. Aggressive bubbling. Lots of gurgling.
Edit2: 2 hours after beginning eq cycle, all three cells at 1.275. 15.9v, taking 3.84 amps.
Edit3: 2:50 after beginning eq cycle, all cells at 1.275, 15.9v taking 3.4 amps.
