Customer Ratings & Reviews

I hate climbing up the latter to change the Battery in the smoke alarm. So I put a battery that will last.

these batteries are great. they last a long time and are very energy efficient. great for smoke detectors.

Well The only thing i could say is, they got the job done. thank you best buy for keeping these instock.

I have finally gotten my Smoke Alarm to stop beeping at me to replace the batteries. Hurray for safety!

I have started using Duracell as it last longer than any other battery. I am happy to make a right choice.

Works as advertised. 2 pack of 9V batteries serves as replacement batteries for smoke detectors. Only word of caution would be to check the expiration date of the battery packs if possible, especially buying them in-store.

Batters lasted longer than normal. The tester I used the batters in functioned for a longer period of time

They’re Duracell at a low price, delivered to my doorstep. How much better can it get?

These batteries are great batteries and they have a long shelf if you do not need to use them right away

Priced right and they work! I buy several packs a year to replace batteries in my smoke detectors.

Dull as dishwater, but you gotta have them. Price is ok, and these are the best on the market.

Works great! fits exactly in a gadget with the shape for a 9v battery. It powered it right up!
