    Bought them for the smoke alarm. So far so good. If I change my review, I probably have larger life issues to deal with.

    These batteries came in clutch when I needed to replace some older 9Vs in a fire alarm. They've held up and haven't needed replacing since. Only minor downside is they're a little expensive.

    Energizer batteries is the primary brand we buy. They last long. We use these for our smoke detector and have to replace them less often than with other brands.

    These batteries are great for many devices that require a little more power. They last a long time so you can install and forget them. Your device just works..
