DL2450BPK Coin Cell General Purpose Battery

Used it in an alarm system [This review was collected as part of a promotion.]

I bought the Duracell Lithium Coin 2450 for a smart scale, and it works perfectly. The battery lasts a long time — much longer than cheaper brands I've used before. Packaging is secure and child-safe, but still easy to open. It's also compatible with multiple devices I have at home, like remotes and medical devices. Definitely feels like a quality product that's worth the price.
