Perfect replacement for my car key fob.
I bought this Energizer 1620 to replace a dying battery in my key remote. It fit perfectly and restored the range immediately—I no longer have to stand right next to the door to unlock it. These lithium coins have a great shelf life, and with Energizer, I don’t have to worry about it leaking or dying in a month. Reliable brand, good price.

Perfect for my friend's key fob
So, my friend's key fob battery died and we went to Walmart and looked at Family Dollar, Food Lion, DG, and Tractor Supply. Nobody had this battery and I was relieved when I could order this to repair his key fob. It fit perfectly and works great.

Different from the image - Read my review
It is a Energizer Lithium battery, but comes in a small blister as you see in the picture. It is part of a larger set or quantity. It is not in the consumer package that is shown in the image. Original battery like the image sells for $6.99 in Best buy Canada. Exact same battery that I received is $5.99 in a blister of 5 in Amazon Canada.
