Amazon Basics 4-Pack 9 Volt Alkaline Everyday Batteries for Smoke Detectors, Long Lasting 5-Year Shelf Life

These are great batteries. They function as they are supposed to and do exactly what I need. Why pay more for a brand name? They don’t get hot and they do what every other battery does - just cheaper.

I'm very satisfied, very good and strong batteries. I bet they can last long too! price is also very reasonable!

My original order was lost and Amazon came through for me and sent a replacement.These batteries work perfect and very happy with them.Not sure how long they will last and will update my review later.For the price, these are a great value!!

So my smoke alarm battery died and it was beeping and beeping and beeping and beeping and beeping and beeping and beeping. It was driving me crazy …went online and found battery put in. Within two minutes, my nightmare was over and I went ahead and bought the big pack because Of the value for my money. Great performance the battery worked perfectly. It fit My smoke alarm. There was some really good value in the four pack. Hell I don’t know about the brightness factor because I’m using them for a smoke alarm, but I know they also fit a flashlight

I recently had a couple of smoke detectors have the batteries wear out and started to beep. I went to Amazon to find replacement 9 volt batteries. I chose the Amazon brand because of the price point being less expensive than the major brands. To my surprise these batteries turned out to be every bit as good and long lasting as the major brands you pay a ot more for. I recommend this brand of battery.

They work well. I've used them in multiple items including smoke detectors with no problem. Would buy again.

Value for money

I got these to make sure that I had enough on hand for my smoke detectors since I absolutely cannot stand the noise they make when the battery is low. I would say they're most likely on par with the name brand batteries at a way cheaper price point.
