If you had a 3 cell battery pack your pack would be 18.5Wh X 3 = 55 Wh of stored energy. When you take battery weight into account you calculate energy density by taking the watt-hours and dividing them by weight. E.g. 55 Wh divided by (battery weight in grams divided by 1000). Assuming this battery weighed 300 grams then 55/(300/1000)=185 Wh/Kg.
Testing on production lines uses the AC method, which is introduced by this article. When measuring the internal resistance of a battery cell using the AC method, an AC resistance meter specifically designed to measure low resistance levels (i.e., a battery tester) is used. AC resistance meters apply a constant-current AC signal to the battery.

Check the Battery. Before calibrating a Fluke multimeter, it is important to check that the battery is in good condition. If the battery is weak or dead, then the multimeter will not be able to accurately measure voltage and current. To check if the battery needs to be replaced, use a voltmeter or ohmmeter to measure the voltage of the battery.

The simplified calibration can be replicated in most laboratories and the results indicated that the more complex the calibration the better the performance regardless of the segment and filters used. The electric power sensor designed by Pai P. et al also involved the calibration of Hall, giant magneto-resistive (GMR) and inductive sensors.
Calibration can improve range prediction by up to 80km (50 miles). To get full benefit, the service may need to be repeated. Some service centers provide calibration for given EVs but this is expensive and time-consuming. Battery calibration is recommended once or twice a year and when buying a used EV.
