  • Patent number: 6037778
    Abstract: An electronic battery testing device and a method for testing batteries are provided. Device applies a small first fixed load and measures the voltage at the end of the first fixed load and then applies a medium second fixed load and measures the voltage at the end of the second fixed load. The device then analyzes the condition of the battery based on these voltage values. A method is also provided involving: (a) applying a first small fixed load to a battery, (b) measuring the voltage at the end of the first small fixed load, (c) applying a second medium fixed load to the battery, (d) measuring the voltage of the battery at the end of the second medium fixed load, and (e) analyzing the condition of the battery based on the voltage values. Preferably the method also involves evaluating the recovery voltage wave form after the second medium load.
