Customer Ratings & Reviews

I purchased these batteries due to my previous batteries in my smoke detector alarm going bad, these new batteries are excellent and definitely worth the money. Ill be buying more to put in my other smoe detector alarms throughout my house.

So far so good. It would be interesting to compare his long this would last compared to other brands

They are great batteries what more needs to be said. Energizer has always led the way in long lasting batteries.

Got this pair at a good price. The alarms in my home use this size, so it was a good chance to change batteries. My previous batteries were also Energizer. Cannot go wrong with this brand.

Quick and easy stop for 9 volt batteries for my smoke detector. I like the energizer brand.

No, not the Metallica song, from the 1986 classic 'Master of Puppets' album, but like a battery that goes in your smoke alarm. That is where I put my battery. Battery is a kick-butt song though. These Energizer batteries are pretty good too! Battery is found in me, Battery! Battery!!

Works..no complaints. Had it stored for a long time, holds charge just fine.

The product arrived on time. There were no problems with the delivery, and no damage to the package. I will not be using the batteries soon, but do expect them to be completely functional.

I've been buying Energizer batteries ( regular and rechargeable) for years. These batteries seem to always last quite a while for my battery operated smoke detectors and fire alarms. I highly recommend this brand.

My Panasonic transistor radio was not working properly or finding the stations I was looking for even when I turned the dial. I replaced the battery and low and behold it works as good as it did when I got it for Christmas in 1972

Batteries... you always need batteries for something. Need them for the smoke detector.

For the price in my opinion these batteries are long lasting and a very good value for the price Would definitely recommend them

Batteries did the job when I needed them to! My fire detector was beeping a low battery alarm and Best Buy helped me out! Thank you.

These batteries are far superior to the nine volt batteries I was using . I will never use them again . I could tell the difference as soon as I swapped out the batteries . They were a little pricey but I think in comparison to the other batteries, the additional cost is worth it.

You know the quality is going to be good and it's going to last long if it's an Energizer battery. Use the 9 volt in my smoke detectors, They tend to be pricey, but with a sale and a bonus certificate it was a great buy.

Please people always replace your smoke detectors batteries! These last a long time

The batteries are great for smoke detecters. These batteries can last longer than most. I've used these before and change them once a year. I suggest that anyone should buy the following batteries. Great product!!!

Always have a couple of these laying around. On occasion my son’s toy calls for one of these. Thankfully I always have one for back ups. Always get these, never cheap out on no name brands.

Energizer MAX 9V Batteries (4 Pack), 9 Volt Alkaline Batteries, good batteries for the price, good service, fast shipping.

They keep going and going and going..... They last very long and that is what I needed for our Livingroom grandfather clock.
