Since the initial publication of this wiki in August of 2018, we've made 10 edits to this page. The electrical charge in 12-volt batteries slowly depletes over time, so if you have a car, ATV, boat or RV that sits unused for weeks at a time, you'll want one of these solar chargers to keep the battery topped off. These gadgets can help extend the life of your battery, and some even include a controller to prevent harmful overcharging. When users buy our independently chosen editorial picks, we may earn commissions to support our work. Skip to the best solar car battery charger on Amazon.

An avid reader and outdoors enthusiast, Joe earned his doctorate in literary studies before making the lateral leap from academia to technical writing. He now lives and works in the inter-mountain West where he creates technical and marketing content, including white papers, solution briefs, and courseware for some of the world’s largest information technology companies. With more than 14 years of experience in the field, he has learned more than he ever thought he would know about such enterprise IT topics as cloud computing, storage, databases, business software, and networking. When he’s not writing about business computing, he can be found outdoors, probably hiking with his family and dog.
