I decided to swap batteries 9v that my Home Insurance sent as a gift at policy renewal. Bad Bad Move randomly one of the smoke detectors would report from one of them Low Battery. Decided to Yank all of them out and use the 2 of these 4 Packs.Never heard a chirp since then knock on wood. Price was competitive.

As far as batteries go, these seem to be the kind I like. I mean really, what can you say about a battery? Not really a fashion statement, not good in the pool, sort of a out of sight out of mind item until you need them. So stock up, because you never know when those little gems are gonna kick the bucket.

They're batteries, what else is there to say. I hope they work and last a long time. As of this writing I still haven't used them.

This sale that Best Buy had on batteries was a great sale. I have never been able to buy these batteries at a lower price. I even got free shipping and they were at my door in two days. Best Buy does a great job of getting the items to you as quickly as possible

When I need batteries that last long and give me great quality for the price I buy Duracell. Always dependable and great price.

Quantum duracell lasts longer than Energizer advanced lithium. Will continue to purchase this product for all battery needs.

I would recommend anyone to purchase electronics, CD'S and other products from Best Buy. The staff is very helpful where to locate products or info on their products. Very pleased with all my purchases & will continue to shop in the store or on line. Also can pay bills on line.

I recently bought this product. Its worth the money and serves the purpose. I would definitely recommend this to my friend.

This product did exactly what I need and what I will need in the future and got a great price on them also.

Great batteries, last a very long time. Would definitely recommend. Great for fire alarms and carbon monoxide detectors.

I still consider copper tops the battery of choice, but several other manufacturers are now very close in performance.
