Primary cells and primary batteries: manganese dioxide cells, zinc-carbon and alkaline dry cells in sizes such as AA and AAA, which must conform to the Indian Standard.

Dry cells are general cargo in most forms but must meet standards; state size, chemistry and shelf life, and avoid short circuits. Batteries are dangerous goods: lithium cells and packs fall under UN 3480/3481/3090/3091 (UN 38.3 test summary, state of charge limits, special packing), lead-acid under UN 2794/2800, and nickel-cadmium or hydride under UN 2795/3496; provide MSDS, correct class labels and carrier approvals, and check destination battery recycling and marking rules.
