    Default Numbers stamped on Carbon Zinc D cell batteries

    I use Family Dollar Carbon Zinc D batteries for some of my industrial flashlights. These are some newer ones that came out this year, since the older Family Dollar batteries were built VERY SIMILAR to (if not the same as) the Eveready SHD Carbon Zinc batteries. These new ones are Chinese made, but they seem to be better in preformance. Anyways; they have two codes stamped on the negative (bottom) end. They are "PD0313" and "ED0316."

    I tried doing a search but found no information.

    I am just curious to see what this is. Does anyone else know?

    I have heard of batches in batteries in the past. What exactly does that mean?

    Thank you; I never thought of that.

    It would definitely make sense. I would assume that PD could stand for "production date" and ED could stand for "expiration date."

    That would give it a shelf life of 3 years, which I have seen Carbon Zinc batteries lasting that long (even though I have always read their shelf lives are only 2 years.
