Customer Ratings & Reviews

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

Solid battery, plenty of power, good price, would get it again.

I needed some new 9v batteries and these did the job. Long lasting and Energizer quality.

Battery provides long lasting power to my devices, excellent deal and product!

Battery lasts longer than the cheaper ones and require less replacement due to the reliability of product

If you need something powered, and it holds 9v batteries, well then you're in luck! Get you some of these bad boys, pop 'em in and BOOM. You're up and running man. Full speed. Usain Bolt style. There's no quit in these bad boys. When you need one yard on 4th and 1 from the goal line, these 9V's are scoring a touchdown every time. If you buy any other batteries, you're making a grave mistake.

Perfect for our smoke detectors. We replace them every six months.

very reliable. keeps on going and going and going. Its very low involvement, never a defect. nothing more to say.

The cost of the batteries at Best Buy was very competitive and the batteries are reliable

Energizer battery last long time and powered my device flawlessly.

Great product ease of use, lasts longer than usual batteries.

great battery , value pack , long lasting , good price

Great battery for smoke alarm. I've used these before they lasted over a year.

I got these to replace a smoke alarm battery that died. At the store, a 9V battery is like $6, so I figured I'd pay a little extra to get 4. I never have extra 9V batteries, so I thought it would be nice to actually have one handy next time I need one. As other reviewers stated, this does not come in original packaging - these came as two small baggies, each with two 9V batteries. I only tried out one of the batteries so far, but it worked just fine.

Battery last a long time and worth the price. Good value.

Batteries last a long time. Trusted brand. May cost more but you get what you pay for.

These batteries have come in great. They have a great life span and are of great quality.

I love this brand and have been using these batteries over 20 years. They last longer than most similar batteries. This is a true premium brand that is high quality and long lasting. Energizer has a well earned reputation as a top notch battery . I use this brand for all of my battery needs and urge you to do the same. Highly Recomended !

Good quality batteries for a cheap price, used them for a steel wool experiment and worked out great!
