5 year batteries

we use these batteries for our smoke detectors because they have a 5 year date. and they do last 5 years almost exactly. since we change them all at the same time they all go out at the same time. be careful to check the date on the battery because the first order we received showed a less than 2 year life. We returned these and reorder. the new order was fine.

Best brand of batteries

I purchased these Duracell 9V batteries for my smoke alarms because I was growing tired of the beeping. Other batteries that I purchased in the past (mainly from Dollar Tree) did not last long. So far these batteries have been holding up, while the price is kinda expensive the overall value is worth it.

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.
