er Energy Conservation Standards - NOPR

The unique identifier for the battery charger or the test data associated with it. 

The intended end-use application of the BC. Categories include: Power tools, Golf cars, Cordless phones, 

Cell phones, Universal BCs, Hand vacs, Shavers, Wheelchairs, Cameras, etc.

Battery chemistry, there are a limited number of options for battery chemistry: Li-ion, NiCd, NiMH, Sealed 

Lead-Acid, Flooded Lead-Acid.

The nominal voltage of the battery, as specified on the battery packaging or as calculated by the chemistryspecific cell voltage multiplied by the number of cells.

The rated amount of ampere hours (Ah) which can be delivered under specified conditions of temperature, 

rate of discharge and final battery voltage. An Ah is a measure of the volume of electricity determined by 

multiplying the number of amps delivered by the time (hours) of delivery.

Value calculated by multiplying current capacity and voltage

Battery energy measured during discharge

The amount of time, from start to finish, of the charge test.

Average of last 4 hours of power consumption.

Recorded over 24 hours (or whatever the test time is); includes maintenance and active mode

The average input power during the no-battery test

The average power consumed during the off-mode test

Calculated Unit Energy Consumption
