Hit the ground running this morning, had a bunch of chores and started knocking them out early. I needed to go over to Landlady’s and drop some stuff off, and while there I borrowed her vacuum cleaner. The only other time I did that was in the middle of the day and I never really paid much attention to how the batteries were getting on through it. From earlier experience I knew it wouldn’t be nice, but it’s also short and not destructive and as long as the inverter doesn’t actually switch off it’s good.
This was a little early in the day for it, the batteries wouldn’t hit float for another hour or so, and so this was an opportunity to note how this particular vacuum pulled down the batteries.
For the record, quite a lot.
So the lesson, I guess, is go ahead and use the vacuum but preferably in the late morning/early afternoon and in short sessions to allow the power to come back up in between. Nothing really surprising learned.
