4 more auto Es and 1.300 at 55F.
That puts them at 2.298 at 60 and 1.290 at the 80F standard for a total gain of about 0.023
I'm going to keep going until I get no increases, but if this is full... this would mean that... after my initial top charge plus 1 equalizing session at 15.9V, the batteries were at only something like 87% fully charged... for a pair of brand new batteries with current date codes.
Man oh man.
I normally have to do two Es to get them full after a few 50-90s in a row, but I don't think doing more Es will be worth it if that means more off the plates.
I did not have to do so many Es to get baseline SG when I got them new two years ago. I did a normal charge with the B&D then an E, then another E. They are great 6s in service.
Just got back from another four- nighter, leaving with them full on Wednesday. Friday morning was down about 235AH (49%) and 12.1v light load. Got them up to about -116AH ( 75%ish), and next day Saturday was down about 255AH (45%), recharged for two hours and this morning Sunday was down about 265AH (42%) and came home. Plugged in and doing recharge to full. I expect to do a couple Es and will likely have to add some water. Then go on Float. Batts in heated space so nothing off capacity 460 in that.
The way I use them, all my 6s over the years have needed water after operating like that. I don't know how guys can say they hardly ever add water. I suspect they just don't operate like that! Microwave, kettle, and toaster lots plus evening TV/DVD and much furnace (ambient 0-8C)
Of course on solar in summer you get to full on nice days so it is a completely different story. You can go for weeks and weeks without using the gen and stay above 75% doing short cycles.
Don't need no steenkin LFPs. ( One of the DVDs was "The Treasure of the Sierra Madre" where the bandit says that famous line :) )
