    I'm hoping to find some type of chart that explains the expiration codes on the Button Cell Watch Battery Blister Packs used by Energizer and some of the foreign(?) suppliers like Blue Dot Trading, Eunicell etc. From contacting an Energizer Company CS rep, I found that MC means they expired in Dec 2019. But, I'd rather not spend 20 minutes on the phone every time I need to know. Some of the sellers on ebay either do not know these codes or they're selling expired batteries intentionally.

    Although I typically order Energizers too, I notice the Sony strips of 5 and 20 I have are marked with a clear "USE BY Month/Year".

    The Energizers I just get from a reliable parts house, trusting them to maintain their stock, and I don't order more than I will use up in a few months. (I get orders shipped from them most weeks anyway, it's no problem to get batteries 5 or 10 at a time.)

    My battery supplier gave me a chart and updated it every few years. It seems that there is no connection to logic. It is simply alphabetical.

    My advice is to buy from a supplier who will give out a chart.

    Good evening, all!

    I don't buy enough batteries often enough to be able to buy in bulk or wholesale. From experience gleaned in my photography days, I tend to buy on an as-needed basis preferentially from a retailer with high volume. Accordingly, I never bought any kind of battery for a photo application from a camera store, preferring instead a high-volume discount store or even a grocer. I have never trusted "Brand X" batteries, no matter how inexpensive.

    Anybody know what the current thinking is on refrigerating or freezing batteries to improve their shelf life?

    Best regards!

    Adding to the articles answer----think of your car battery in the dead of winter or a blazing summer. Essentially the same thing.--not good for it.
