Amazon Basics 8-Pack 9V Alkaline Batteries, 5-Year Shelf Life - for Smoke/CO Detector, Electronics & AudioThe Nordic Swan EcolabelThe Nordic Swan Ecolabel

This battery has done really well so far for me in the past few years. I have had it in my smoke detectors for quite sometime and have not had to change it much. They are still running pretty strong when I checked the power. I also checked the one I had in storage and it lost a little bit of charge I feel but it is still a good battery. The battery installs easily into my smoke detector and I have yet to find a need to replace them. I only replaced my other branded one with these. They have not had any issues as of yet. They all individually wrapped in plastic which is good for storage but a bit annoying to open them one at a time. Overall the battery has done really well with my smoke detector. They have lasted for a very long time in the detector and storage. I have had no issues with low power as of yet which is good. The down side the individual wrap is a bit annoying.

After battling my beeping fire detectors, first one, then another....after inserting these 9 volt Amazon batteries, I.finally changed to new, other brand batteries, and they worked. I sat down to write an unflattering review of the Amazon batteries but after discovering that I had purchased them in 2018 and they were going on 7 years old....they are guaranteed for five years and they certainly exceeded that. So...I apologize, batteries. Good on you. I only gave them four stars because the clear wrapping on each battery is hard to detect and remove.

Needed batteries for all of our smoke alarms, it’s been about a month, so far so good. Batteries fit & work as they should. I wanted a bulk pack with a decent price.

We always purchase our batteries from Amazon. Costco used to be our supplier but we don't get there often enough so when we run out we have to make a special trip or wait. Using Amazon, we get the same quality batteries in one day.

We have several electronics and we are very hard on them. I have tried so many brands that I have to give this a 5 star rating because of the price. As far as quality, they function as well as any other brand on the market.

I usually buy Duracell batteries from that big membership warehouse store but this time I thought I would try these Amazon Basics instead. They perform well at an unbeatable price.
