Why do we need a solar trickle charger
Three reasons to own a Solar Battery Trickle Charger
1. Batteries Naturally Discharge - Automotive batteries naturally discharge when not in use.
2. 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.
3. 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.

Modern cars, feh

I have a Subaru, a VW, and a Prius Prime. None of them have a single cigarette lighter outlet that can be easily made to stay on while the car is shut off. Ironically all the manuals state that this is in order to save the battery.

Recharging My 12 Battery in my new Truck

I bought a new 2021 Truck and since then the modular for charging the battery and many other safety features were disabled due t a low battery voltage... I need all the safety features to be up and running ,especially at my age nearing 80 years of age. Afte numerous times at the dealership for warranty repairs I decided to get a small solar battery charger to maintain the voltage where it should be in the battery.. Works GREAT
