RAYOVAC A1604-2J ALKALINE 9 VOLT BATTERIES 2 PACK CARD

These work like a charm. We installed these in our smoke detector about a year ago and there is no chirping just yet. They seem to be going strong after all this time, quite happy with the results and would purchase these again. Would recommend to anyone. 

I just replaced 6 batteries in smoke detectors in November. Here it is Dec 21 and at midnight, of course, one of them was chirping. Sadly I can't trust the rest of them now and will have to go with the actual recommended ones that are imprinted on the detectors themselves. I hadn't noticed that until I purchased the Rayovac ones as I use them in everything else.

I received Rayovac 9V 4-Pack HIGH ENERGY™ Alkaline Batteries in exchange for my honest review. A couple months before receiving these batteries I had changed the batteries in my smoke detector and it had acted a little strange, but it did go off when I tested it. When I received these batteries, even though it was early I changed it to one of the HIGH ENERGY batteries and discovered the smoke alarm wasn't working at all! I tried the other battery, just in case the new battery was defective, it didn't work either. Thanks to receiving these batteries I got a new smoke alarm and it may save my life!

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.]
