Solar Car Battery Charger Maintainer 12V Waterproof Solar Panel Portable Solar Trickle Charger for Car Truck Boat Lawn Mower RV Trailer Tractor ATV

WHY DO YOU NEED A SOLAR TRICKLE CHARGER? Three reasons to own a Solar Battery Trickle Charger:  Batteries Naturally Discharge - Automotive batteries naturally discharge when not in use. Vehicles have a small but constant battery drain - Modern vehicles have upwards of 30 body control modules (computers), alarm systems, immobilizers and lock monitoring. These units all consume electricity from the battery. That's why in a week or two with no or little vehicle use the battery can become discharged. Battery life is shortened if it is not kept charged - A 12V battery that is not correctly maintained above 12.4V can suffer from sulphation. Sulphation is the main cause of battery failure. That's why the auto battery easy goes to dead when vehicles are left standing for long periods.  Solar Car Battery Trickle Charger Package Includes:  1* 12V 10W Solar trickle charger with 4.75 ft cord 1 * Alligator clip adapter with 22.8 i
