 Three reasons to own a Solar Battery Trickle Charger: 

• Batteries Naturally Discharge - The car battery also naturally discharges when not in use, resulting in less and less power until it runs out.

• Vehicles have a small but constant battery drain - Modern vehicles have upwards of 30 body control modules (computers), alarm systems,immobilizers and lock monitoring. That's why in a week or two with no or little vehicle use the battery can become discharged.

• Battery life will be shortened - A 12V battery that is not correctly maintained above 12.4V can suffer from sulphation. Sulphation is the main cause of battery failure. This is why it is easy to run out of power when the vehicle is left for a long time.
