The present disclosure relates to a lighting device (100) comprising a lighting unit (102), at least one application unit (104), and a battery housing (106) comprising a first battery compartment (108) with a first electrical contact set (110) for accommodating and connecting a first battery and with a second battery compartment (112) with a second electrical contact set (114) for accommodating and connecting a second battery, wherein the first and second battery compartments are configured to force an exclusive spatial accommodation of only one of the first and second batteries in the battery housing at a given point in time. The lighting unit is electrically connected to the first electrical contact set for being powered by the first battery in a first operational mode and the application unit is electrically connected to the second electrical contact set for being powered by the second battery in a second operational mode.

For each cell in a plurality of cells from a same manufacturing run, a first and a second cell characteristic are received in order to obtain a plurality of cell characteristics. For each cell, a batch compatibility number that is associated with a number of compatible cells that that cell is compatible with is determined based at least in part on the plurality of cell characteristics. The plurality of cells is sorted according to the batch compatibility numbers to obtain a sorted list of cells. A plurality of compatible cells to include in a battery is selected from the plurality of cells, including by evaluating the plurality of cells according to the order of the sorted list of cells and beginning with the lowest batch compatibility number.
