This is a brand I always look to buy when I need batteries on my smoke detector, my remote controls, and my flashlights. Love energizer batteries.

[This review was collected as part of a promotion.] I haven't had these long enough to know how long they will last, but I received this product quickly and they work as advertised. The packaging is nice too, because you can store the batteries in the package after use. I received 4 C batteries in this package.

[This review was collected as part of a promotion.] We use a lot of batteries at once because of all of our son's toys. It's great not to have to change batteries for a while. These batteries are long-lasting and reliable. We also are using some for our smoke detectors since we don't have to worry about switching them out for a long time. My wife is a musician and she uses these for her tuner/metronome.
