By way of exception to the first paragraph, for back-up batteries that have as their primary function to ensure continuity of a power source, the functional unit is defined as the ability to provide one kWmin (kilowatt-minute) of backup power capability at any moment over the lifetime of the battery. Accordingly, the reference flow for back-up batteries is the weight of battery needed to fulfil the defined function and shall be measured in kg of battery per kWmin of backup power capability divided by the service life of the battery in years. All quantitative input and output data collected by manufacturers of back-up batteries to quantify the carbon footprint shall be calculated in relation to that reference flow.
