Customer Ratings & Reviews

I like being able to buy a long-life 9 volt batter battery in a two-pack. I don’t use a lot of them, but it is nice have a spare available when I need one.

We use these in clocks, toys, and other things around the house. They always deliver great performance and last a long time. Price is comparable to other top batteries.

You can find cheaper batteries sure, but they will not be as good as Energizer. This company consistently delivers high quality batteries at a reasonable price.

Choosing batteries is not something you should try to experiment with: try to save by buying unknown brands. Energizer and Duracell are equally good and I always buy them when I need batteries

I always find that the Energizer batteries give me the best long-lasting batteries. These are 9-volts for those pesky smoke detectors that annoyingly chirp when the batteries need replacing.

I like that the battery has a long shelf like. I like to keep one on hand in case the smoke detector battery starts chirping, this way I can replace immediately.

Energizer batteries always seem to work good. We usually use this brand.

Excellent battery…. Last a long time. Would purchase again

Good strong piece of tool to keep on hand or house

gets the job done, very reliable and you get a reputable brand

One of my biggest pet peaves is hearing the constant chirping of fire alarms with low batteries. To extend out the time as long as possible, I turn to the Energizer bunny. No more chirp.

I bought these for my Kidde smoke alarms. They're the recommended brand for them. They should last for a year.

Battery is just as advertised. Works great in my smoke detector. I definitely recommend this battery. I will be purchasing additional batteries in the very near future

Very useful product. Lasts well. Very dependable and good value.

Great battery. Would buy again. And again and again and again.

Energizer MAX 9V batteries are long lasting and exceptionally batteries.

Always a good idea to buy batteries where you know the stock is rotating regularly. The same batts in a drug store might sit on the shelf for months, but at Best Buy they're moving out.

The batteries in my smoke detectors were chirping away, so picked these up when I got my phone. They are batteries, and they work. What more can I say?

Works great. Just like expected. I got what I paid for

Smoke detectors no longer chirping! The bargain batteries installed by the builder didn't really last, but these Energizer batteries run strong for years. Silence in the house now.
