Duracell Coppertop 9V Battery, 4 Count, Smoke Detector, Long-lasting

Fast shipping. Item as described. Great price

I noticed that common complaints about 9V batteries in reviews include: 1) Batteries were loose; not in original packaging and 2) That they turned out to be at the end of their shelf life so didn't last long. These Duracell Coppertop batteries are in their original packaging and they are each stamped with 2031, compatible with the stated the 5 year shelf life.

Always buy this brand

I got this 4-pack of 9V batteries to replace the old ones in our home smoke alarms. Great brand, and having fourin apackis super convenient! They have a 5-year storage life, so I can keep the extras in the drawer without worrying about them going bad. I like that it wlill keep our detectors working properly and prevent annoying chirping noises at night. It is a simple purchase that gives me peace of mind for future home safety.

I bought these primarily to keep fresh 9V batteries available for our smoke detectors. There are plenty of places where I'm willing to save a few dollars on batteries, but safety equipment around the house isn't really one of them. I've used Duracell Coppertop batteries for years, and they've always been one of the brands I trust. With smoke detectors, I want to put the battery in, test the alarm, and have confidence that it's going to be there doing its job. The 4-pack is a convenient size because I can replace batteries as needed and still have extras stored away for the next low-battery warning. And anyone who has ever heard that unmistakable smoke detector chirp in the middle of the night knows exactly why having spare 9V batteries in the house is important. Somehow they never decide to start chirping at 2:00 in the afternoon when you're wide awake and standing next to the battery drawer. I still test our alarms regularly and replace batteries according to the smoke detector manufacturer's recommendations rather than waiting solely for a warning. They're not an exciting purchase, but they're an important one. I'd much rather have four good 9V batteries sitting in the drawer than hear that 2:00 a.m. chirp and discover I don't have a single replacement in the house.

Has been my favorite brand of batteries for years

Great 9 volt batteries for smoke detectors. It is worth buying the Copper top if you want the best batteries for your smoke detectors.

Good battery.
