    Not much to say about batteries. They work. About 1 year of the shelf life was gone but these last a while. Had some rewards to burn and bought these at Best Buy.

    Needed batteries and wanted to use my $5 Best Buy bonus money, so bought these batteries, something I can always use and like to keep on hand for smoke alarms. When the siren line sound starts, you need to fix it ASAP>

    Great purchase of our own. I love the way that the batteries always maintain a great power source for my lighting equipment. Sometimes I use the batteries for my wireless microphones as well. I love that you can count on energizer batteries.

    I like that these come in a 4 pack, 4 smoke detectors, 4 batteries. 9v cost a little more but I used a $5 certificate so it made these a good deal. They last way longer than a year so well worth the cost

    Good ones but too expensive. After buying them compared prices from other stores and were way expensive.

    I was in the Best Buy store for something else and remembered that I needed a 9 volt battery for my smoke alarm. I found the well stocked battery section and conveniently picked up the 9 volt that I needed. One stop shopping.

    I buy these batteries once a year to replace the batteries in all my smoke alarms. They always last reliably over the year, so I'm not always replacing this or that one during the year.

    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.
