Promaster XtraPower CR1220 Lithium Battery

These little cells keep my kitchen scale running for months without any voltage drop-off. I've used three so far and every single one delivered the exact same steady performance.

I was a bit worried my garage door remote would stop working, but this battery fit perfectly and the door clicks open instantly now. The CR1220 coin cell is exactly what I needed for such a small device.

My car key fob needed a CR1220 and this little coin cell fit perfectly right out of the blister pack. It's been holding strong for three weeks now with no voltage drop, which is exactly what I hoped for from a lithium battery.
