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.
