text: Product Description Read more 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.

text: Product Description Read more Read more Why do you need TOPSOLAR Battery Maintainer Trickle Charger Modern vehicles have more than 30 body control modules, alarm systems, anti-theft, and lock monitoring. All of these devices consume battery power. The power consumption of these modules is very small, but if the vehicle is not used or rarely used for a week or two, the battery will discharge until it runs out. If you don't keep charging, the battery life will be shortened. Sulfation is most likely to occur if the 12-volt battery voltage is not properly maintained above 12.4 volts. Sulfation is the main cause of battery failure. That's why it's easy to run out of batteries when the vehicle is parked for a long time. Once the battery runs out of power due to natural power consumption, it may never recover all the power. But as long as there is sunlight, the TOPSOLAR battery charger and maintainer will generate current to protect your battery from running out of power. Read more Q&A Why does my multimeter fail to detect any voltage when the "Normal Working indicator" is lit normally, under no load and sunlight? This is normal . Our solar panels are brand new products sent from the factory. When delivered to consumers, the solar panels are still in an inactive state. When consumers use it for the first time, they need to connect the load to activate , and then use a multimeter to measure the voltage that can be read. Waterproof and Long Lasting Material Waterproof and long-lasting material for added durability. Designed for long-term use. Safe & Humanized Junction Box If the Normal Working indicator turns from black to green, it indicates that the solar panel has received sunlight and is working normally.  If the Polarity Reversal indicator turns from black to red, it indicates that the electrodes are connected backward, please connect them in the correct way IMMEDIATELY.
