Customer Ratings & Reviews

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.

They work as good as they are expected to. No complaints.

The Energizer Max 9 volt batteries were exactly what we needed to insure the smoke detectors in our home were ready for any emergency. We are aware of the necessity to replace batteries regularly. We always keep replacement Energizer batteries available when needed for the many devices in our home which are battery dependent.

I have always gotten Energizer 9V batteries for my guitar pedals and they have never failed me. Great price and last a long time for guitar pedals.

pretty decent price, confident I have a good battery

Normally if I need batteries I go Duracell. These Energizer batteries were left, great value, they do the job, and satisfied with the quality of Energizer.

I actually haven't checked how these compare to Duracell, but they sure are way better than Kirkland brand! I bought these for my garage door opener and expect it work for at least a few years.

Work like a charm. Would recommend to anyone. Good price too

these are batteries what more is there to say they're batteries

These batteries have changed my life...ahh got ya...just kidding. Not much to say as there isn't a heck of a lot going on with batteries. They're pretty simple. These have decent life like most batteries and the only thing that keeps me buying Energizers is that they are made in the USA.

Does what it should. Bought them for smoke detectors

These batteries last for ever. I can't remember the last time I had to replace on of these. They are a little pricier than others, but definitely worth the money.

This batteries last long and it worh the price. I used for different electronics and never use a different brand.

Long Lasting Power Batteries! When it comes to hassle free. I always count on this brand.

Really, it's a nine volt battery so there is only so much you can say. The fact that it has such a great shelf life (5 years) makes it a good choice if you need to put it away while you wait to replace one. Great for smoke detectors and I put mine in a handheld taser. Works as promised!
