Duracell 2016 Lithium Battery, 4 Count (Pack of 1), Child Safety Features, Lithium Coin Battery for Key Fob, Car Remote, and other devices CR2016 3 Volt (3V) Cell

I stocked up for my key fobs, remotes, and even an old calculator, and Duracell’s 2016 coin cells have been steady and dependable. They nestle snugly into slots, boot up my devices instantly, and somehow keep kicking long after I’ve forgotten I even put them in. Plus, they store like champs—never worry about finding dead batteries in a drawer when something actually needs one.Here’s the honest caveat: while I love that the cell has a bitter coating to deter kids (major safety win), it’s also tough to open. Expect to need scissors—or some serious finger wrangling—to break into the package. Not ideal when you just want to swap batteries mid-rush. But afterward? No leaks, no power dips, just reliable energy tucked into the tiny iconic Duracell copper top. Great peace of mind, minor packaging annoyance.

The Duracell CR2016 3V Lithium Battery is a reliable and long-lasting power source for small electronics. I've found it to be incredibly dependable for devices like car key fobs, watches, and calculators. The stable voltage output ensures consistent performance throughout its lifespan. It’s an essential item to have on hand for when you need to quickly replace a dead battery. The packaging is secure and easy to open, making the whole process hassle-free.

A good battery, it works. When I put it in my flashlight and turned it on, all of the bits of light or electricity that are stored inside the battery did not come gushing out all at once. So I can rely on the flashlight to work when I need it.
