A solar car battery charger is an excellent way to keep the battery fully charged on vehicles that are seldom operated, such as boats and ATV's. New technology has made solar battery chargers both more efficient and less expensive.
The way a solar battery charger works is simple. It is basically plug and play. Most units offer a choice of connecting directly to your battery with clips, or using the cigarette lighter to feed the energy to the battery. The latest technology has made them efficient even on cloudy days. Sunlight is transformed into energy that can be used by your vehicle's battery, and the battery level is maintained. In addition to keeping idle batteries charged, such as on an RV or farm equipment in storage, a solar battery charger can be used to operate light or small appliances in rural settings. They can keep you from draining your battery while charging your cell phone with a car's cigarette lighter or operating the radio while the engine is off.
Solar car battery chargers are sometimes referred to as solar battery maintainers, because of their disclaimers stating that, while they will maintain a battery level, they are not designed to recharge a dead battery. However, many users have reported success at reviving a dead battery with a solar battery charger, although in some instances it did take a bit of time.
Prices and wattage for a specific solar battery charger will vary by manufacturer and model. The Sunforce 50022 5-Watt Solar Battery Trickle Chargeris one of the best selling products. Weighing just four pounds, this portable solar charger is easy to use and gets very positive reviews from most customers. It is ideal to maintain the battery on idle vehicles or to use on a campsite. A sure bet.
The Coleman 72002 CL-600 9-Watt 15-Volt Solar Panel Battery Charger / Maintaineris another popular solar car battery charger. Designed to prevent battery drain in cars, this is also a useful charger for campers who want to power coolers, laptops, lights, or even portable televisions. This unit weighs less than 7 pounds and measures 3" x 18.3" x 20.9".

Yet another excellent solar battery charger is the Sunsei SE-150 2.25-Watt 15-Volt Solar Panel Battery Charger / Maintainer #25003. This solar charger weighs less than two pounds and can be mounted on your dashboard or in the window with suction cups, so there is no need to drill holes. It comes with an adaptor for the cigarette lighter as well as several battery clamps.
No matter what kind of vehicle you need to keep charged, a solar car battery charger can make the difference between one that starts, and one that does not.
