    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.

    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.

    I bought Duracell as I used it with my smoke and carbon monoxide detectors. Saftey is paramount and I knew it will last the 6 months and then some.

    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.

    This are the typical batteries that you will need for remote controls cars. I have bought them for two cars and so far they are lasting a good amount of time. Totally recommended.

    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.

    The Energizer Max 9 volt batteries were exactly what we needed to insure the smoke detectors in our home were ready for any emergency. We are aware of the necessity to replace batteries regularly. We always keep replacement Energizer batteries available when needed for the many devices in our home which are battery dependent.
