2 Pcs Brillar CR2016 Lithium Button Cell

These batteries offer fantastic longevity. I’ve used them in my car key fob and slim digital watches, and they consistently last much longer than the generic brands. It’s great to have a power source you don't have to worry about replacing every few months.

The CR2016 is quite thin, and these Brillar ones are manufactured to exact specifications. They snap perfectly into tight battery compartments like calculators and small remote controls without any connectivity issues or loose fitting.

I really appreciate that these are mercury and cadmium-free. It makes me feel much better about using them in household electronics, knowing that they are a bit more environmentally responsible compared to older battery tech.

Getting two in a pack is perfect. I usually only need one for my device, so having a spare on hand for emergencies—especially at this price point—is very convenient. It saves me a second trip to the store later on.

The blister pack is sturdy enough to keep the spare battery secure until I need it. The clear warning labels about keeping them away from kids are also a helpful reminder for parents, as these tiny cells can be easily misplaced.
