Energizer  CR2016 3V Coin Cell Lithium Batteries - Package of 2

This brand is my go-to for all battery needs. Whether it’s for my tea lights, car key, or other small electronics, these batteries never disappoint. They’re reliable, versatile, and truly long-lasting—just as promised

Only battery you need. Long lasting. I used to get other bands but it will die sooner than this one. It totally worth it for the price and the best part is is you can pretty much get it anywhere

I’ve relied on Energizer 2016 lithium coin batteries for various small gadgets, including key fobs and remote controls, and they’ve consistently delivered excellent performance. Their battery life is outstanding, lasting far longer than budget options, so I rarely need to replace them. Installation is simple, and the batteries fit perfectly every time without complications. The packaging is very secure—though a bit tricky to open—which actually provides extra peace of mind for safety, particularly around children. Overall, Energizer is a brand I trust for dependable, long-lasting power.

I always get these batteries for devices that draw little amounts of power. These do seem not last the longest. There is packs of 2 that you can get but by the time it's time to use the second one it isn't full battery anymore. It's why I buy them in packs of 1 only.

Always dependable. Great batteries at a great deal. Never have to worry about performance compatible with anything that uses a 2016 packaged so they can't be gotten into by little kids so that's cool

Great battery. Very long lasting and dependable. An excellent choice for light remotes and some smart/ traditional watches. Also great to use with thermometers.

These batteries are highly durable and the size is perfect for keeping them organized. Long lasting and compatible with a lot of different devices.

These batteries are well made. I've tried other brands that don't last as long and crust over time. I ONLY trust Energizer for my batteries needs!

Works for long periods of time, use it not only in my car key but also the same type battery for garage door remotes, probably have to change my battery once a year if that. Absolutely love it!

"This Energizer 2016 battery is excellent. I used it for my car key fob, and the compatibility was perfect. What stands out the most is its consistent power; you can really notice the difference in the range and the immediate response of the device. It is a highly useful item that provides peace of mind, knowing it will last a long time without losing energy. It is definitely my go-to brand for small devices that require precision."
