Customer Ratings & Reviews

Quality batteries that last a long time and are affordable.

Always reliable. Long lasting. Good price. Would buy again.

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.

They work perfectly in our smoke detectors. These batteries are always available at the front of the store.

Best Buy has great prices on all their batteries. Would highly recommend shopping there.

Good purchase. No problems at all. Pick up with no hassle.

What can I say, the batteries that keep on ticking!

Great. They worked out great. Good purchase. Used them for fire detectors

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.

we received the batteries on time, It is very convenient to have them in the house for when we need them

I use these for my smoke detectors, and they work well. I replace them once a year rather they need them or not.

These always make an excellent gift for someone on your Christmas list!

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.

Great Price for replacement batteries for smoke detectors in the house. Always need to keep some on hand for those midnight wakeup beeps!

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.

They did exactly what I needed then for. 9v battery’s.

Energizer battles seem to be best them seem to last a long time. No complaints I would recommending them.

Really excellent batteries because they keep on going and going!

Works well even in cold weather. Better pick for the price.
