Customer Ratings & Reviews

For the price compared to Duracell, it is a good battery. Although, between using Duracell and Energizer over the time I have been buying batteries, Duracell has a longer life span but much more expensive. Never measured time of life vs. money between the two. Good battery overall.

These are the only batteries that have never failed me. I use several types of wireless audio systems and digital equipment that are all battery operated and Energizer batteries always work better than every other battery I have tried. I have tried several other brands, which do not perform nearly as well a Energizers. Energizers seem to last so much longer.

Our 2 new smoke/carbon monoxide detectors require 9V batteries and were not something we normally have around. I was pleased to see the Energizer 2 pack for such a reasonable price for such a dependable brand.

The Energizer batteries are good and durable. They last longer than many others I’ve tried and always deliver consistent performance

Great 9V for smoke detector or garage door opener that last a long time.

I got these batteries because it was that time of the year to check the fire alarms/ Carbon monoxide detectors and I never buy the cheap batteries when it comes to me and my pet, I like Enegizer batteries they last long and because I was at Best Buy buying something else I pick these up.

These Energizer MAX 9V batteries deliver long-lasting power, perfect for my smoke detector and other uses. A bit pricey, but worth it for the quality. Highly recommend!

I ordered Batteries on line. The process was quite easy. I actually had them delivered to my home and wanted to see how that process was well. They were supposed to be here on a certain day and they were not. It ended up being like maybe four days when it was actually delivered!! I actually ordered something now, but I’m picking it up in the store!

Over the years I have tried many brands of 9volt battery in smoke alarms,walky talkies,garage door openers and too many other applications to name,Energizer 9v batteries have not once failed to perform flawlessly, long lasting power and with proper use have never leaked once.

I recently purchased a 4 pack of 9 volt batteries from Best Buy and I couldn't be happier with my purchase! These batteries have been reliable and long-lasting, providing power to my devices without any issues. The convenience of having a 4 pack ensures that I always have a spare when needed. Best Buy's quality and service continue to impress me, earning this product a solid 5 stars. Highly recommend for anyone in need of reliable power!

Those batteries are great specially for important items like smoke detectors to use with, trust and durability to keep them on mind

Batteries were what I needed and what I eventually got. Unfortunately, although I ordered them for 1 hour pickup, when I got to the storem they weren't available. 3 days later after another trip to the store, I finally got what I needed. It's a weird system--- they told me at the store that I'd have to cancel my own order, and since I'd used a rewards certificate to buy the batteries, it wasn't possible to get my rewards back in my account immediately (so I couldn't just walk over to the battery section and get something off the shelf). Pickup was unfortunate as well- I had to wait on the normal checkout line (which was also handling returns) to get my online order. A lot of opportunities for improvement! First, know your inventory and don't say something is available for 1 hour pickup if it isn't. Second, have someone occasionally see if anyone is just picking up an online order so those folks don't have to wait an inordinate amount of time as everyone checks out for something that's already paid for and should be a quick pick-up. Third, empower the store employees to cancel and online order rather than telling the customer to do it him/herself; if the order was using rewards, then immediately credit the rewards back into the account so they can be used on something in-store since you're already there to pick up the item that should be available and isn't. I hope some of these ideas are helpful!

Works great in my acoustic electric and great value for total tech memvers

I use these for my acoustic electric guitar and haven’t had to change batteries in months. Best batteries for long term playing.

We have the rather old Kidde model i4618AC smoke alarms in our house, but they require 9-volt batteries and we were running rather really low on them.

With my membership, I got an amazing deal. Perfect pack of two to replace my fire alarm and security box device battery.

These things last forever. I use it for the smoke alarm and I change them once a year. They still have life in them but just to play it safe I always change them once a year. It's always best to do that because if you wait for the device to beep maybe you say I'll do it tomorrow or you procrastinate with other excuses. I like to do it the way I've been doing it.

Since I haven't had the need to use these batteries yet, I'm hoping that they're as good as the ones that I've bought in the past. One of the Eveready batteries that I bought from Best Buy in the past had a dent in it, but the Burbank store wasn't able to give me any kind of store credit since the time had run out on my receipt. I don't think that any one uses all the batteries that they buy as soon as they get them home.

These batteries last longer than the rest. Energizer is my go to battery.

Last long and does the job ! Used it for my alarm system have yet to replace it but no need so far and had it for months
