Scotty, I have a 2015 Audi A4 2.0T Premium AWD with 45K miles. The vehicle isn't driven much. I'd be interested to know your thoughts on using one of those solar panels that plugs into the cigarette lighter to help keep the battery charged. Good idea? ... or no? It's an AGM battery.
Thanks for your advice!

He did a review on one once. See if you can find the video. I would get one that clamps directly to your battery however
@bobthehatking you can't find it?
@bobthehatking I don't know if this is the video you're looking for but a quick internet search for :"Scotty Kilmer Solar Charger" found this in about 10 seconds:

@bobthehatking Thank you gentlemen! I appreciate the input!
I'm assuming the power socket has to be an 'always on' outlet vs a 'switched' one, no?
@vegas-atc yes it does. And a regular trickle charger will be far more reliable. Especially in the winter time.
@MountainManJoe Appreciate the response! We have a lot of sun out here in the desert. Lol.
Point well-taken on the reliability.
@bobthehatking photovoltaic cell output depends greatly on sun angle. Presuming you're in Las Vegas, Nevada, which is about 4,000 miles from the equator, you're getting about 13.5h of daylight sun. More than enough to account for normal battery self discharge, provided a sufficiently sized solar panel. (around 5% per month for lead-acid or about 5 amp-hours.
