Trickle auto charges employ the use of a battery regulator to regulate charging rate and prevent overcharging, charging your vehicle's battery at a rate similar to the rate at which it self-discharges so as to maintain full battery capacity. Charging at too fast of a rate or overcharging can cause damage to the battery.
Using a car charger is very easy. Most trickle chargers consist of a simple box (where the "guts" of the charger reside), a power cable and two alligator clips. Before connecting everything, be sure to set the voltage and amperage appropriate for your battery. Check the switches and buttons on the charger box and set them prior to connecting the charger to a power source.
