## Description

Product description Sunway solar battery trickle charger maintains the charge of car, truck, marine, tractors, ATVs, snowmobiles, boat,water crafts or RV 12 volt battery! Why do I need a solar trickle charger? Three reasons to own a Sunway 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. With Green LED charge indicator connector. It lights on while the solar charger is producing power. What's more, compare to the built-in charge indicator, an independent indicator connector makes the solar charger has better waterproof performance.

Review: Fun in the sun - The solar charger works great. The solar charger voltage during the day is around 15 volts DC. Even on a cloudy day, It runs off day light. It will not over charge during the day or draw from the battery at night. My truck I don't use only once a month keeps the battery topped off perfectly. I check it with my tester all the time. It does what it is designed to do.
Review: Works great - I purchase this to keep our forklift battery charged when not in use. Does a great job.
