Coppertop Batteries

We use these Duracell Coppertop 9V Alkaline Batteries 2/PK in our smoke dectectors and thesy last a long time! We bought our home February 2010 and have only had to replace these batteries twice so far. I am sure we will need to buy some more maybe next year since the first ones lasted around 6 years before we replaced them. Even though they suggest they are good for 5 years they can last longer if the smoke detectors do not go off much. When I used to burn food my smoke detectors went off very often. lol We started using the Duracell brand and my cooking has improved very much. I would recommend these batteries to everyone.

Stick with what works

Have used this brand for many years - because of their performance. I especially like the new packaging instead of the card style - which was a pain to use.

Duracell is always reliable and worth the price. They have long life without any problem. This is my go-to brand, especially for smoke detectors where safety is paramount.
