Dont have a shelf life as long as name brands.
By Soldat_1958 on Reviewed in the United States on June 11, 2025
These are OK batteries, but I would not recommend buying a lot of them for storage for later use, as I did. (All sizes). Brand name batteries usually have about a 10 year shelf life. I have a large home, 15 rooms total with a smoke/heat detectors in every room except the bathrooms and laundry room. So I bought quite a few of these in a couple of orders because I sawp out annually. A little over a year after my first purchase, half the D's in the box were discharged and most of the AA and AAA's were done. Buy them to use immediately, not to use later would be my suggestion.

Hope these live up to the 5 year life span

Hope these live up to the 5 year life span. Backup batteries for smoke detectors. The so called 10 year batteries in the detectors last nothing close to 10 years... the life span of the detectors themselves. So you end up replacing them again and again. I have tried other so called long-life batteries... Lived in the house for 15 years, have changed the detectors once already, where new when I moved in. Replaced the batteries at least 5 or 6 times in some of the detectors, so I am getting maybe 2 years per battery that is supposed to only be used as back to main power? Oh and the detectors themselves get more expensive, but the quality gets worse... there should be a law about that, since these are required by law to be installed.
