Abstract
The battery tester has a casing having an input device and two detecting wires, a microprocessor, a loading unit and a battery power status detecting unit. The microprocessor builds a strategic decision process therein to determine a loading time for a battery according to the battery capacity, battery voltage and detection requirements having 1/N CCA and a loading time input from the input device. Therefore, the battery tester detects batteries with different capacities and has accurate detecting results.
