Abstract
An electronic battery tester for testing a storage battery determines a condition of the battery. The condition is a relative condition and is a function of a dynamic parameter of the battery and an empirical input variable.
Claims67
An electronic battery tester for testing a storage battery, comprising:
- Kelvin connections configured to couple to terminals of the battery;
- measurement circuitry coupled to the Kelvin connections configured to measure a dynamic parameter of the battery and a voltage across terminals of the battery;
- an empirical variable input configured to receive an empirical input variable;
- computation circuitry configured to provide a relative battery test output as a function of the dynamic parameter and the empirical input variable, the relative test output indicative of a condition of the battery.

A method for testing a storage battery comprising:
- coupling Kelvin connectors to positive and negative terminals of the battery;
- measuring a dynamic parameter of the battery using the Kelvin connectors;
- receiving an empirical input variable;
- determining a relative test output indicative of a condition of the battery based upon the dynamic parameter in the empirical input variable.
