Great batteries for my smoke detectors and metal detectors. Very reliable and lasts a long time. A good value since they do last longer than the dollar store brands, and nobody wants to skimp on prices when it comes to safety and your smoke detectors

You really cannot go wrong with having a steady supply of these essentials on hand at all times.
