Long lasting and great value

Best value for the longest lasting batteries. I like buying the four pack so that I can keep them around. I put these in all of my smoke detectors and they usually last over a year.

Great battery choice

Great battery! Lasts a very long time and is cheap to replace. Highly recommend to anyone that needs 9v battery. I use it in my kids toys that require them and it lasts months with one battery.

Quality batteries

Great batteries for my smoke detectors and metal detectors. Very reliable and lasts a long time. A good value since they do last longer than the dollar store brands, and nobody wants to skimp on prices when it comes to safety and your smoke detectors

It was great value for what you get from the batteries. It is easy to open and store them when you don’t need to use them. It worked great as advertised.

These batteries always work well for me. I have NEVER had a leakage. They don't get warm temperature at all. It has lasted me a very long time. Easy to insert and take out.

Battery is a battery

I typically buy Duracell batteries over others, no real reason for it, guess the rabbit ads don't appeal to me. These work with any 9 volt product, and to be honest I used one to test a soliinoid in my car. They last pretty long and easy to get out of the packaging.

I have always used these for all of my smoke detectors. Duracell is the one brand I trust with my families safety. They last much longer than others.
