Last night I used very little battery power and it was at 15.3v finish by 10:30 am.
I checked SG at 11:30 when 1.8 amps were required to hold 15.3v.
1.265, 1.270, 1.270
I left it at 15.3v until late afternoon when sun was nearly too low to hold 15.3v.
1.270, 1.275, 1.275
I know 16v could get it to 1.285, but 6 hours at 15.3v couldn't.
Electrolyte still clear, level about 1 cm below arms.
I checked it today because I was charging and checking my Landlord's various neglected batteries and had the hydrometer out anyway.
I don't really remember when I performed the last EQ, I'd have to check this thread. I just been using the battery basically without concern as to how much I am using or how fast I deplete it. Lights fans, TV audio through the stereo, charging Li-ions, compressor fridge turned to slushy milk temps. Laptop on when not even looking at it, ect. Stereo on all day long......wasteful.
With the exception of last night I am using 45 to 65 Ah each night. Have not driven in 4 days so pure solar recharge daily.
This battery is working for me. It will be interesting to see how long it can hold up.
