Customer Ratings & Reviews

Energizer batteries is the primary brand we buy. They last long. We use these for our smoke detector and have to replace them less often than with other brands.

I love to keep spares of this battery for smoke detectors around the house. I can always rely on the Energizer for a great product

What can I say about a great battery? Yes, they are really great and last a long time in my smoke detectors.

These batteries are great for many devices that require a little more power. They last a long time so you can install and forget them. Your device just works..

They work well so far. We’ll see how long they last, which to me is going to be the true measure of their quality and value.

I always use Energizer batteries. These batteries have a long battery life. Bestbuy had a great price on the 2-pack. I only use Energizer batteries in my home.

getting 25 points for this review. energizer batteries are good. Probably no new news for anyone though.

this is good for use in smoke detectors and other electronics that need long battery life. Li - but NOT rechargeable

Great batteries at a great price! Highly recommend these.

They are batteries. They work. My smoke detector needed the battery replaced.

All ways the best battery long battery life as al

I have purchased many batteries over the years and have found Energizer Max to be the best for long lasting and dependability.

Bought them for the smoke alarm. So far so good. If I change my review, I probably have larger life issues to deal with.

As expected, it lasts longer than generic cheap batteries.

If everyone has a smoke detector and they use 9 volt batteries, why are they so hard to find. Thank you Best Buy for carrying one of the top brands too

These batteries are great, true most things are going bluetooth, etc.. and we won't need Duracel for much longer. But, I still use them now, everyday, in everything.

Bought these for the smoke detector and won't have to change the batteries for a long time. Now it's up and running and quiet.

Good value. I never run out of batteries. Between the remote controls and the video game controls, I could never find a battery when I needed one.

They last a good amount of time God price for the benefits

This is a battery for my smoke detector, so reliability is important. A consumer has limited ability to evaluate reliability. Thus I went to Best Buy and bought the battery Best Buy recommends, relying on Best Buy to have selected a good, reliable battery. So far the battery seems fine. The price was reasonable.
