    Thought they would last longer then the non max type but I found they don’t. I’ve gone back to regular alkaline type.

    The batteries were used in a smoke alarm and I expect these to last a long time. This is a good buy compared to generic brands.

    Reasonably priced at store and good battery to use for replacement in fire alarms. However, there are 9V's made by Energizer for that specific purpose. Stores charge lasts close to advertised duration.

    Energizer batteries are better than other brands of batteries, especially for “always on” medical equipment.

    I've never purchased a more reliable 9V battery. We use them for all our smoke and CO detectors/alarms. The five year batteries eliminate the yearly changing of the batteries as well.

    My batteries seen to last longer when I purchase them from BestBuy. I don't know why they last when I purchase from BestBuy but I'm not going to try to figure it out. I will just keep purchasing from BestBuy.

    Got batteries for my distortion pedal used with my Stratocaster guitar. They work, exactly as one would expect a new battery would. So, if you need 9 volt batteries for something that requires 9 volt batteries, these 9 volt batteries will work.
