I was advised to use Energizer for my insulin pump. Turns out that was great advice. Other batteries don’t last very long in my insulin pump so I end up using twice as many batteries. Energizer goes the mile. I won’t use anything else for my medical devices ever again.

These are ABSOLUTELY terrible. As an example, one of my regular uses for them is in an analog clock that uses one AA battery at a time. The Duracell batteries Sam's used to sell would last between 2 to 2-1/2 YEARS before needing replacement. These batteries last 2-3 MONTHS. Less than 1/6 the duration of the Duracells. That's absolutely ridiculous in this day and age, and at this price point. And their performance in other electronics is just as bad. They're just garbage. I'll never purchase Energizer batteries again.

Pack was busted and 48 batteries were rolling around the bottom of the box.

Great way to keep your supply of batteries up to date.

Left on front patio in the rain and packaging was soaked so thoroughly, batteries fell right out.

They are the best They give longer service than any other.

Too many batteries, gave half to a friend. Hopefully the 10 year shelf life is correct.

great product. didn't even have to leave the house. shipping took about 1 week.

Good battery. Great sale price

3 batteries used, lasted 4 hours and died
