About this product

*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. Thats 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. Thats why the auto battery easy goes to dead when vehicles are left standing for long periods.
