    I use these batteries for the fire alarms at my home. They last a lot longer than regular batteries. I would give it 5 stars, but these batteries are super expensive. I'm too lazy to change the batteries often, so I was willing to spend the extra money.

    Some years ago i put four smoke alarms in my house and and then they starting beeping. That four pack was just right and should last five or more years.

    These batteries worked as expected...no issues. The quality that we've all grown accustomed to when it comes to the Energizer brand. No imitations here like one might find on the internet from other sources. Bought these for our smoke detectors in our home. They are reliable and last between seasonal changes.

    Just needed some batteries and found some at a great price. I had a $20 credit there I thought I could use up before it expired. I guess I didn't know how it worked. Just got the bill for the purchase and it's for the full price.

    Needed 9 volt batteries that actually last a long time so I could use it in my smoke detectors. Haven't had any problems since and it seems to last longer than other brands I've used. Has a decent shelf life as well if not immediately using it.

    I always keep 9 volt batteries on hand and now is the time to change your batteries in your smoke detectors. I change them in the carbon monoxide detectors too just in case. Best Buy usually has the best prices and I order the batteries from them.

    Got some batteries for the smoke alarms througout the house. I change the batteries every year just as a good habit. They probably last much longer and it's probably a bad habit on my part but I just feel better because it's for the smoke alrms.
