This plug-and-play solar trickle charger prevents the natural battery drain in 12V lead acid batteries found in motorcycles, cars, boats, recreational vehicles, tractors, etc. This natural drain tends to happen when 12V batteries are left unused during an off-season. Lead acid batteries last longer when kept fully charged at all times, even when not in use. Also includes a built-in charger regulator to avoid over-charging and reverse discharging.

Position the solar trickle charger when it receives the most direct sunlight as possible and connect to the battery using one of the included connectors. Proven effective during all types of sunlight-including cloudy conditions.
