I’ve posted in other threads that I kept a 10W solar panel on the dashboard to keep the battery topped up. No more, at least for the time being. I first bought a 5W panel , thinking that would be adequate to make up for parasitic drain on my infrequently driven Tucson. However, measurement reveale…

While I have no experience with them, I’d have spent a bit more for ‘Battery Tender’ brand: <a href="https://www.amazon.com/Battery-Tender-Solar-Charger-Maintainer/dp/B08BFC6G1G/ref=sr_1_1_sspa?keywords=battery+tender+solar&qid=1659540264&sr=8-1-spons&psc=1&spLa=ZW5jcnlwdGVkUXVhbGlmaWVyPUFUNFZNWURCUkM1TU4mZW5jcnlwdGVkSWQ9QTA1OTc0NzAyQ0tFMEUxTjY0VjdEJmVuY3J5cHRlZEFkSWQ9QTEwMjU1ODQzRjZYWUxOSkM4WlZWJndpZGdldE5hbWU9c3BfYXRmJmFjdGlvbj1jbGlja1JlZGlyZWN0JmRvTm90TG9nQ2xpY2s9dHJ1ZQ==" rel="noopener nofollow ugc">Amazon.com: Battery Tender 5 Watt 12 Volt Solar Panel Charger and Maintainer with Charge Controller, IP67 Weatherproof, Includes Windshield and Handlebar Mounts, Ring Terminal Cable and ODBII Connector : Aut…
