Class 9 Classification and Regulatory Requirements Overview
Cells and battery packs have transportation and packaging requirements based on their storage capacity Watt
hours (Wh) or their equivalent lithium content (ELC) depending on the country of origin and transportation mode.
For purposes of transportation regulations, a battery pack and cell are defined as:
•
A battery pack consisting of two or more cells that are electrically connected together and fitted with
devices necessary for use, for example, case, terminals, marking and protective devices is considered a
“battery
”
. However, a single cell battery is considered a "cell."
•
A cell is a single encased electrochemical unit (one positive and one negative electrode) that exhibits a
voltage differential across its two terminals.
Determining the Nominal Watt Hour Ratings of Cells and Batteries
To determine the nominal watt hours of a cell, multiply the nominal voltage (volts) of the cell by the cell’s nominal
capacity (Amp-hours).
Eq 1.
Nominal Watt hours (Wh) of the cell = Nominal Voltage of the cell (V) x Nominal Capacity of the cell Amp-
hours (Ah)
