Customer Ratings & Reviews

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.

This is the long lasting battery I brought for my lockbox. Can’t go wrong with this excellent battery.

Worked perfectly in my smoke detector. Also used it in my speaker

Its long lasting and durable. I recommend this product .

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

Use these in my guitar with active hambuckers. Last forever.

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.

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.

Always good to have a great 9 volt battery on standby from Energizer.

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.

See above (great batteries). Long lasting, great value.

Good price compared to other stores and oddly enough these batteries are harder to find these days.

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.

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

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

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

The Energizer Max 9v batteries are a must to have on hand. I always make sure to get them at a great price and they are great batteries for the smoke alarms.

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

Always needed for smoke detectors, etc. I usually have some of the more common sizes around, but the 4 pack is perfect to have a back up battery when you need it.
