[This review was collected as part of a promotion.] I’ve had these installed in my smoke detectors over a month now and they are still working well. I like that I can get two in a pack, so I was able to swap out both of my smoke detectors at the same time.

[This review was collected as part of a promotion.] These batteries work but realized they are the wrong ones I had originally wanted. It worked out fine because I did need some batterie so thank god I had these insteads. Great product.

[This review was collected as part of a promotion.] No issues so far. I was so happy to have these the power was out for 2 1/2 hours at my home and they lasted in my flashlight the whole time.

[This review was collected as part of a promotion.] I received these batteries a few days ago, they will come very handy for our upstairs smoke detectors, we change batteries every year in the fall, and we have known the Rayovac Brand to be reliable and long lasting. I like the fact, that they come with a 5 year power guarantee.

[This review was collected as part of a promotion.] We use these 9V in the smoke detectors, in our resident gate remoter, the Alkaline 9V can last a long time, so I don't need to change the battery frequently. I always stock up on these 9V batteries, and Alkaline brand sells at a reasonable price compared to similar brands. We use other models of Alkaline batteries in our home too, we like that these batteries lasts longer and cost less.

[This review was collected as part of a promotion.] I was able to get the Rayovac - D 4-Pack HIGH ENERGY Alkaline Batteries and boy am I glad I did! My family always has a good supply of AA & AAA batteries laying around (but never any D batteries)! I got these just in time as a hurricane hit us and we Lost power. Wow was I glad to have had these on hand because we have some larger flashlights (for in case of emergency!) we keep in the closet, and they had been in so long the batteries had died, so i put in my new Rayovac high energy alkaline batteries and the flashlights worked perfectly until our power was turned back on! I would most certainly recommend these batteries to family & friends!

[This review was collected as part of a promotion.] I received these Batteries a few days ago, I used them in my heavy-duty flashlight that I keep in my tornado preparedness kit. We have used the Rayovac Brand for years and we know they are reliable batteries. We also like that they come with a 10 year power guarantee.
