  • What buyers say about Energizer A23 12v Alkaline Batteries

    The price was the best of all 6 stores in the immediate area.

    I initially wasn't big on the packing but I found the batteries to be good and that's all that matters. I'm taking away one star because I don't like the idea of them being individually packaged.

    I bought these batteries from here because I couldn't find that size in the local stores, and the price was better than some of the other sellers.

    I think the batteries were better than the actual packaging because they were in a tiny bag.

    I got an extra one for free because I received three sets of two instead of the 5 battery strip, the batteries are fresh, and the package was good.
