Well, a little surprise just now.
First right on the stickers on the top of the batteries it says pro rata warranty. Proof of purchase required...low maintenance..bla bla bla...
All the SG's rose!
The range was 1.305 to 1.260 with the thermometer on the hydrometer saying to add 7.
1 cell at 1.260 formerly read 1.250 then 1.235
2 cells at 1.270 one of these cells formerly read 1.255 then 1.230
2 cells at 1.275
2 cells at 1.280
3 cells at 1.285
1 cell at 1.300 This cell was 1.290 then 1.280
1 cell at 1.305 This cell was at 1.270 and then 1.275
Some of these numbers read higher than my first readings when the batteries were new.
After that first aggressive EQ cycle, the level in the cells was a few mm above the hanging arms.
Tonight they were several mm below on all of them.
I don't know why the solar could not reach 14.8 today despite starting on nearly fully charged batteries.
I don't know if the rise in SG is due to sitting at or near 14.7 for 6 hours today. I did drive a whopping 8 miles today, but no alternator current to these batteries.
Or perhaps the BatteryMinder 12248 actually did something that 15.6 volts at 16 amps could not.
Anybody else notice it is hardest to get the bubbles off the float on the lowest reading cells?
The one cell which only read 1.260 appeared like it had a lot of micro bubbles, and it was the most difficult to get the bubbles off the float. I actually quit rinsed the whole Hyd, wiped it and the float clean before being able to get a read without bubbles sticking to the float.
All other cells the electrolyte was clear, and the cells 1.285 and above shed the bubbles easily.
I'm gonna run the batteryminder all night tonight in Maintenance mode, but it really does not like my cycling fridge and shuts off often.
I did take the batteries out of parallel and ran a 5 amp load on each and they performed very similarly.
