Product reviews for High Energy Premium Alkaline Battery, 9V, 2/Pack

I received these batteries for free to test out. We put them in our smoke detectors and so far there have been no problems. They work like a charm.

So far so good! Working, great power and no draining. Been using steady for radio several hours a day since recieved them. Lasting long!

I like knowing that there are a variety of good batteries out there and I am confident that Rayovac is one of the companies that take long lasting portable power seriously. I am satisfied that with their 9volt battery in my smoke detector that I am in good hands.

I received these batteries free for an honest review. They are the best batteries \
I ever used. They last forever. A good battery through and through

They were very easy to install in my device and was so thrilled with how strong and loud the sound that came through making me think that these batteries will last a long time making them a great value
