I use this 9volt batteries every year in our smoke detectors because I know they will be dependable and lasting for whole year. Thank you Duracell.

Always need batteries. Duracell is a must. Don't have problems with explosions like some other batteries. Last a long time as well.

Made my semi annual purchase of very high quality batteries for the home smoke detectors. Long shelf life.

It was a available and the product was delivered very quickly. Good Price too.

What is there to say about batteries anyway? They last longer for my remotes than other brands of batteries, the pricing is competitive with other brands carried at Best Buy and no issues with finding dead ones in the pack.

Duracell Batteries are the only batteries I use. They last a long time and are worth the money!

Best Buy is fast and has great products. Staff is very knowledgeable. Good service. Thanks kindly

The Duracell batteries that I purchased were at a great price point and work great.

I've been using Duracell batteries exclusively for at least the last quarter of a century. They have consistently proven themselves to outlast all of the other brands. I find Ray-O-Vac to be the next longest lasting battery to Duracell, but it comes in a distant second to Duracell. Whether it be AA, AAA, C, D, 9-volt: it doesn't matter. Duracell outlasts the others in every category.

Purchased for my son remote control car. The have great power and last.

Duracell is my favorite brand of battery. Great price, Great performance.

two pack 9 volt good price and excellent quality, for plenty of use.

We have about 5 million smoke detectors at our house. All of them are on the same system and for some ungodly reason when one of them goes out [has a dead battery] every detector on the system starts that horrid chirping sound. We had to replace all the batteries at once. Now we just swap them all out once a year and these work better than the other brands.

Good quality good value for the amount of batteries in the pack
