### ⭐⭐⭐⭐⭐ Review
*by E***N on 7 January 2026*

These fit perfectly for items that require 9v, the battery life seems to be just as good and as strong as some other name branded batteries. They help me not go crazy, I cannot stand that chirp and I have like 4 smoke detectors in my house. I also noticed that the light on my scale is much brighter than before, I've never needed a new battery and the battery that it came with didn't power it up as much as this one.
