The sun will last as we know it for at least another five billion years, so there’s plenty of time to use it as an energy source for automotive, sport, and marine batteries. Right now, Amazon has a Black Friday deal on a battery maintainer that can effectively convert that solar energy into something more useful.
The Schumacher Electric 2.4W Solar Car Battery Maintainer is on sale for $23 at Amazon, 42% less than the $40 it’ll run you outside of Black Friday times. It’s designed to be mounted anywhere on your vehicle, but it’s small enough to move around easily as well.
Schumacher Electric 2.4W Solar Car Battery Maintainer, $23 (was $40) at Amazon
This device works by trickle charging your battery, charging it at a rate equal to its self-discharge rate. That’s why it’s called a maintainer; it maintains a steady charge level, helping to optimize battery health and extend battery life in the process. It works with any 12V battery like those commonly found on sport vehicles like ATVs, motorcycles, cars, and boats. The water-resistant solar panel itself uses thin-film technology that absorbs a larger spectrum of light, so it works well even in cloudy or low-light conditions. At just 19.38 inches long and 10.25 inches wide and weighing just 2.25 pounds, it’s easy to move around. It comes with a 12-volt DC adapter (for plugging into the cigarette lighter), clamp adapters (for attaching directly to the battery), and mounting screws — everything you need to get maintaining out of the box.

One shopper bought this maintainer for their motorcycle, and they were “extremely satisfied” with their purchase. “The solar panel is incredibly efficient and charges my battery quickly and effectively, even on cloudy days. It has helped me maintain my battery life and saved me the trouble of having to jump-start my bike every time I want to use it.”
Another happy customer, this one with a truck equipped with a battery-draining alarm, was similarly pleased with this “simple and well-made” product. They wrote that it’s “perfect for what I needed it for” and especially liked that there’s “no need to worry about overcharging a car battery since it’s so low in wattage.”
Whether you’ve had battery issues in the past or simply want to avoid them in the future, the Schumacher Electric 2.4W Solar Car Battery Maintainer is a valuable weapon in that fight. And for just $23, it’s worth grabbing one for every battery you own.
