Abstract
An electronic battery tester connectable to a battery through any one of multiple cables. The tester includes an input that can couple to any one of the multiple cables. Also included is a memory that contains multiple calibration values, each calibration value corresponds to a different one of the multiple cables. Test circuitry, which is coupled to the input and to the memory, detects which one of the multiple cables is coupled to the input, and tests the battery as a function of one of the multiple calibration values that corresponds to the detected one of the multiple cables.
