The life of the battery

We love energizer batteries that is all we use in our household. We just seem to think that they last longer and are better all around would recommend to all our family and friends. 

Used for smoke alarm

Worked in one smoke alarm, but when i replaced it in another, it kept chirping. Probably have to change the whole alarm

Great lasting battery

These are the only ones I use in my smoke detectors. Great battery and last a long time. When safety’s number one for your family, these are the ones you want.

Reliable Batteries

I've used these batteries for years and they are always reliable. They last much longer than other brands. I would definitely buy them again. Overall a great value!

Best product

The packaging of the product is awesome when it comes to the size of the product. The durability is great too. The fitment is awesome and I recommend to anyone

I forgot my smoke detector needed batteries!

I have used these batteries for my smoke detectors many times and they seem to work the best from the other competitors. I have only had a few that didn’t seem to last as long as most but overall, these batteries will keep annoying smoke detector beeps away!

Longevity

I bought these to replace the ones in my smoke detectors. Hope they will last long so I don't have to replace them soon. The ones I took out were put in 4 years ago and still have full power, so hoping these will last as long.

Overall I was very pleased with this battery.

It has very good performance. The drainage of this battery is minimal. This battery is very easy to dispose. The temperature of this battery stays cool.
