Because of the size (dimensions) commonly the battery I can say anything negative. I was put off by some reviews before buying, but the 9V battery could be easily installed in our smoke detectors.
My experience, it certainly will not regret at least at home to have a 9V battery in stock to fit a smoke alarm immediately.
I have installed this battery and provided with a small PostIt, when it was built, so can only * sometime * (hopefully it will take longer) which tell how long she's doing their service in a smoke detector. (I also had to date still more new test candidates, so that even a comparison will be possible.)
Until I possibly can report negative, the article gets me the best possible rating. I rate the battery well out of the ground before it goes blank, because I like the negative reviews because of too large dimensions too weighted see here.
