I contemplated ways to put a serious evening-long load on my new/old battery bank, and found myself instead re-writing the lyrics to Junkfood Junky to the new title Lightswitch Nazi. (In the day I spend like a sailor, just as wasteful as I can be/But at night I’m a lightswitch nazi, good lord have pity on me)
Point being, my old two-battery bank actually fit my usage habits pretty well, except for gloomy times mostly during winter when I was forced to economize further. I guess tonight I’ll go around and turn on every light in the cabin and leave them on till bedtime, then see what the morning voltage is and how long it takes to recharge. I’ll have to force my inner nazi to sit down and shut up while I’m doing that, because damn. Last January when I spent a week in Landlady’s house in the city, I went around turning off unused lights in what was probably a fairly annoying fashion. It’s a standard line with me: Nothing will turn you into a lightswitch nazi faster than living off grid. I’ve been doing it for ten years so excuuuuse me.
But what surprises me is not so much that I’ve got more voltage margin to play with, that’s perfectly logical. More battery cell plate acreage, more storage capacity. But why is my battery bank recharging more quickly than before? Those two things do not go together. It’s not just more capacity, the whole system is working better in every way.
It led me to wonder if maybe one of those two Interstates wasn’t quietly going south. So I dragged out one of the two pieces of indispensable test gear I do have…
I’m a little confused. Gratified, but confused. Maybe I just haven’t allowed for the longer days.
