Abstract
An auto-controller is adapted for incorporating with a battery charger to charge a battery by using a thermo-control and current balance technology for extending a service life span of the battery while being cost effective. The auto-controller includes a resistor having a predetermined resistance for electrically connecting to the battery charger wherein the resistor generates heat when a predetermined current flows through that defines a reference temperature for the battery charger, and a thermo sensor operatively positioned adjacent to the resistor for detecting the reference temperature and selectively switching the battery charger on and off, whereby when the reference temperature is above a control temperature preset in the thermo sensor, the battery charger is switched off to not function and when the reference temperature is below the control temperature, the battery charger is maintained in a switch-on condition to continuously charge a battery.
