MANUFACTURER CODE / DATE CODE
A manufacturer's code is stamped onto the battery case at time of its manufacture. This manufacturers code contains information as to the date of manufacture, type, manufacturing plant, etc.

A two letter code ( B0, A9, etc.) is also placed on the battery to make it easier for resellers and consumers to identify the production date. The code is on a sticker affixed to the battery or hot-stampded into the case cover along the top edge. The first letter represents the month, and the second number represents the year. The picture below shows B9, which is February 1999. Fresh batteries are always the best. Refer to the battery vendor or supplier for this information.

STICKER DATE CODES A = January B = February C = March D = April E = May F = June G = July H = August J = September K = October L = November M = December
