PKCELL 9V Battery Carbon Zinc for Smoke Detectors 6F22 Battery,Ultra Long-Lasting

Needed 8 for my smoke detectors. These do quite well for 1 fifth of the price in a store here.

Well packaged and ready to use. Work well.

Good value

All is good

A good product at a very good price.

I purchased a 10 pack January 2024 I used 3 batteries from the pack. I use them for smoke detectors. The first battery I used from the pack did not last more than a year in the smoke detector. Now in May of 2025 I had to replace another one of these batteries in a smoke detector. Unfortunately the 7 remaining batteries are dead. As soon as I installed one, the smoke alarm low battery “chirp” started again. I tried the same battery in 2 other working smoke detectors to check if it was the smoke detector that was the problem, but they both “chirped “ low battery. I continued this process until I found out that all the rest of the batteries were dead too. The company advertises a 3 year shelf life. These batteries are not worth the hassle of dealing with the chirping smoke detectors and only being able to get some use out of 3 of the 10 pack. I hope this helps you to avoid buying these batteries. I will not buy this brand again.
