Whoops
I realised yesterday that with Christmas and lockdown I hadn't been out in the car since the 20th - so pretty much three weeks. I decided I'd better give it a run and it was as well I did. I got out to the car to find that the last time I'd used it I'd left the solar charger I bought after killing a battery in Lockdown 1 face down in the passenger footwall, which doesn't do a lot for it's charging efficiency*. And when I turned the key there was a very distinctly laboured "whhhhhhrrrr" before the engine caught, so the charge was right on the edge of not being able to turn the starter.
But it did manage, so I took it out for a drive for a while to charge up the battery and I'll try and do it a couple of more times this week, but whoops, that was close.
* The idea isn't to charge the battery enough to use, but to keep enough charge flowing into it that I don't get cells dying, as has happened regularly in the past - that way the AA will just need to jump-start me, not sell me a new battery.
