The new battery is on order, but in the mean time I’m thinking that something like this might be a decent way to keep the current battery topped off. On my recent three-day weekend the car sat for two days and was a little slow to crank on the third day. Today the electrical system seemed to reset itself, as evidenced by the clock going back to its default time; I thought the car didn’t start because I didn’t push in the clutch, but it seemed to be more severe than that. And when I went on vacation a couple of months ago I came home to a flat battery that might have been OK with something like this.
I like the idea of the lighter plug, but since my power socket doesn’t provide power when the car is off I suppose that I would have to find another way to hook this up; I think the alligator clips would be a bit of a pain, especially during winter.

My VW came with one that plugged into the ODB port. I’ve moved a few times since I got the car and I honestly don’t know what happened to the panel. I only used it a few times when the car was new(ish) so I couldn’t really tell you if it worked worth a damn or not.

Sounds like you’ve got bigger problems then an unregulated low amp solar charger would solve. Noticable drain from 3 days off sitting isn’t normal

If you don’t have a charge controller, or even an inline diode, you’ll have the battery draining through the solar panel.
You’ll need at least a 30-watt panel with a suitably sized controller — the cheap ones from Harbor Freight work well for lead-acid — connected directly to the battery.

It probably is for a battery that is well over 5 years old...

I’m with this bloke.
Mum puts her cars on trickle chargers if she goes away for a couple of months. Mainly because a modern Land Rover doesn’t have an off switch for its electronics. But its fine for a week or so.

I’ll have to let you know how old the Niva’s battery is. It hasn’t run for more than five minutes (probably in total) since then. This was in early August:
!!! UNKNOWN CONTENT TYPE !!!
And that was the longest it’s ran, when I drive it into the garage just past the fence on the left in the thumbnail. I’ve started it a couple times in the last two weeks just to make sure certain things got put back together properly.
I’m going to go pull the battery now because I know it’s getting low and I don’t want it to freeze. It’s dropped below -20 a couple times already.

Not really. Even if your battery is on it’s last leg still you shouldn’t be loosing a lot of charge over a few days time. Sounds like you’ve got a slow drain problem.

Well she’s either five years old or fifteen. I woulr have to guess five. And this is what she did on the load test after mostly sitting for six months:
A little on the weak side I guess but not bad at all. Read 12.5V on initial hookup. 21°F outside, don’t know what the unheated, uninsulated garage is like but I wasn’t super excited about doing this without proper gloves on, lol.
