12 Energizer CR2 3-Volt 3V Lithium Photo Batteries (6x2)

I use a bunch of these yearly for about 20 Samsung SmartThings water sensors. They will typically last more than a year. I have no reason to expect less from this current batch.

Great batteries for my golf rangefinder at a great price. With the amount of golf that I play (2-3 rounds per week) and how much I use the rangefinder, each battery will last around 4 months. I split the cost of this package with two other friends who also play golf. Will definitely order again.

I needed batteries for my smoke detectors - they seemed to have the best price for the amount that I needed - 12 batteries. They came a day earlier than promised and seem to be everything that a battery should be! :)

I bought these because I got a camera and it needed these types of batteries in the stores these batteries are very expensive so I just decided to go online and purchase them through Amazon my battery life is amazing none of the batteries got hurt in travel

I use these for the dog collar that goes with an invisible fence system. They last longer than other brands I've tried. My dog patrols the perimeter several times a day and although he knows where the boundaries are, the collar will activate if he gets a little too close. This is when the battery discharges. As I said, other brands have not lasted nearly as long as Energizer. I highly recommend!

So glad I can buy these in packs of 12. I use these for my male Rottweilers shock collar, and I was buying these in 2 packs for $12. Works good. No problem in them dying fast. So glad I found these.

Great seller.

It’s worth the money.
