My Screwy 31
First off let me say I am not stressing over this. It's just a battery, it is only money, it is meeting my overnight needs, but it is displaying strange behavior, and I am curious as to why. So th...

Another Sunday Hydrometer dipping.
I used 43 a/h last night, and averaged 38 this week. ~97% solar recharge each day. With one or two alternator blasts in the evening for a few miles.
I was a little later checking today than previous Sundays. It had been sitting at 15.3v for about 3 hours and taking 1.2 amps, after ~2 hours at 14.7v All loads still on the 31 battery, not switched to the other.
I dip the Hydrometer, 1.285, all three. Temp compensated, as all readings have been.
This is 0.005 higher than I've ever been able to get this battery upto. I assume it is due to water loss. Which is noticeable, but nowhere near the danger zone.
I wonder if this is the zone I should never fill it above? The SG level sweet spot perhaps.
And this 1.280+ reading came without me having to run the voltage upto 15.9v for up to 2.5 hours as every other Sunday has.
Not what I expected today.
Considering backing off the voltages a smidge for this week.
