Still ticking. I've been taking 35 to 55AH a night from it, and voltage at 48AH from full under a 5.5 amp load has been touching 11.8.
I've not checked SG, and my absorption voltage is now just 14.4v, and it has been holding the battery there from ~Noon till 6PM.
Last night at 55AH from full, when I turned off the laptop, voltage rebounded to 12.1v in 2 minutes under a 0.8 amp load, which surprised me.
Yesterday morning was partially cloudy, and I fed it some Meanwell amperage for an Hour. It was accepting 47.5 amps for a while from the Solar/meanwell combo.
So the Fat lady has still not sung on the screwy 31.
