Mex must be right about the battery and how to attempt to fix it.
I am nervous about trying that. This battery is not a heavy duty constructed Lifeline, able to take such treatment. This one might be able to take it, or not.
I would like to know what might happen if I do nothing and just carry on as before. Need a crystal ball. I don't need to do anything till October now that solar season is here and we stay above 75% SOC, so I have time to decide.
I suppose the 8D has been leaning on the two 27s once the bank gets below 75%, but there has been no sign of trouble. Can still run the microwave, toaster, or kettle by inverter with no alarms.
EG, recent off-grid no solar, after two days needed a recharge of the "450AH" bank on the morning of the third day. Trimetric showed "resting" voltage at 12.4 and AH down 204AH so at 10C that would be right for 50% SOC.
Ran the 75 amp charger for one hour and 18 minutes at 75 amps then amps started to taper. At two hours of recharge, AH now minus 73AH, so back to about 80% SOC. Drove around some later that day and got some alternator charging and solar exposure, so gained another 35AH before returning to the wooded campsite. So everything looking good and working great.
Lurking in there must have been this 8D with its "issues", but if it has been like that since I got it a year ago, why should I worry about the year to come? Maybe I should just wait and see if anything actually goes wrong and deal with it then. I have five months before 50-90s time starts again.
EDIT--LY says his AGM gets to where its "full" amps acceptance number rises to above the .05/100 and it goes back down after he gives it a good goosing using his conditioning method.
This 8D has been recharged since yesterday's test and at 14.8v, it got down to 0.6 amps, well below the 1.25 amps for the .05/100 rule. I then jacked up the voltage to 15.5 and amps jumped to 2.5 but quickly fell back down to 0.8 (the "wall" Mex talks about AFAIK) so I went to 13.6 Float banked with the two 27s. So today all is quiet on the backyard front (for now anyway!)
