1. A method of testing the fully charged capacity of a battery comprising:
- providing a battery tester, the battery tester comprising a temperature sensor, a display device, and a pair of leads;
providing a battery, the battery having at least two terminals;
attaching one of the pair of leads of the battery tester to one of the terminals of the battery and the other of the pair of leads of the battery tester to the other of the terminals of the battery;
utilizing the temperature sensor of the battery tester to assess an approximate temperature of the battery;
utilizing the battery tester to assess a voltage between the terminals of the battery when the leads of the battery tester are attached to the terminals of the battery as recited;
utilizing the battery tester to apply a momentary load to the battery when the leads of the battery tester are attached to the terminals of the battery as recited; and
utilizing the battery tester to sample a voltage response across the terminals of the battery when the momentary load is applied to the battery as recited so as to access a fully charged capacity of the battery.

Abstract
A battery tester is disclosed for measuring the fully charged capacity batteries. The battery tester preferably comprises a temperature sensor, a resistor, terminal leads, a back-lit liquid-crystal-display. The battery tester operates by applying the resistance between the terminals of a battery via the terminal leads for a period of preferably a millisecond.
