[This review was collected as part of a promotion.] My smoke detector uses a 9 volt battery and I follow the recommendation to change the battery every 6 months when we change the clocks. I am currently using an Energizer MAX Alkaline 9 Volt Battery. It comes in a 1 pack. I buy them as I need them but the label says it has a 5 year shelf life and I do like that the battery itself shows the expiration date on it. I have never had my smoke detector beep to indicate there is a low battery and I do a test every month to make sure it is working, so I will stick with using Energizer batteries since they work.
[This review was collected as part of a promotion.] These are perfect for the kids high use toys and smoke alarms. They’re long lasting and dependable. This is the brand we trust to use, high quality and efficient. They outlast compared to others we used before.
[This review was collected as part of a promotion.] Energizer MAX 9V battery is always going to be a good battery with a long lasting battery life. The great thing about this battery is the shelf life. 5 years. If you like me, I could have batteries for years. I received this product for free for my honest and unbiased review
[This review was collected as part of a promotion.] I always use energizer brand 9 volt batteries in my fire alarms. they last a long time. The shelf life is five years, so I like to check the manufacture date when I get new batteries. It's good to rotate the batteries & use the older ones first of course. Love the pink bunny!!
[This review was collected as part of a promotion.] Energizer has always made quality batteries and the MAX line is no different and their best yet. I have used the double A's in the past in Xbox controllers. I don't have a lot of use for the 9 Volts, except in the smoke alarms in the house - which in reality is one of the most important uses. I replaced all my smoke detectors with the MAX line and hope to not have to worry about them or hear the low battery beep for a long time.
[This review was collected as part of a promotion.] This is my go to brand. I know when I need something to last, I go with energizer. When you need a 8 volt you know it’s for something that drains power, so I had to change the battery out in my daughters favorite singing princess /karaoke along toy, I got an energizer Max. It lasted through constant use for a very very long time before. I can’t wait for the constant singing shows my daughter will put on for me now.
[This review was collected as part of a promotion.] This is a great battery! It works great and super easy to install. The packaging is super convenient! I will highly recommend this brand to my friends and family! I can't wait to buy more! I am so happy that I got to try it!
[This review was collected as part of a promotion.] I just replaced my old Energizer battery with a new Energizer in my transistor radio. I always like to keep a battery radio on hand in case of outages. My old one had been in there for over a year. It still had some juice to it, but was not as good as new. when. I put in the new one, my radio played nice and loud . the Energizer Max is a good dependable battery
