Title: Worse than standard alkaline 9v
Review: I purchased 10 of these batteries from a local dealer 3 years ago to go into my 10 smoke detectors. Half of the batteries failed within the first year and the local dealer I purchased these from replaced them and three of those failed within their first year along with a couple more from the original set. Overall these have less life than I was getting from standard Alkaline 9v batteries. Next time I'll go with a major brand of Lithium 9v batteries rather than these off-brand ones.
