Use in key fob
I use this battery in my car's key fob. Energizer makes good batteries, that last a long time. I keep an extra in my pocketbook just in case I need to replace it. I think it is worth the money.

Great quality and price for these batteries. I've had trouble finding them in the store, always sold out or don't carry them.

They work perfectly in small devices like key fobs, remotes, watches, and medical monitors. Each battery delivers consistent 3V power, and the 4-pack is convenient to have on hand for replacements. They come well-sealed in child-resistant packaging, which is great for safety, though it can be a bit tricky to open. Still, once you get them out, they perform flawlessly and last a long time without losing charge. Overall, these are high-quality, reliable batteries that get the job done — a solid 4-star buy for everyday electronics.

Smart home remote battery replacement
These do last a long time in most applications and are worth the price premium over the really cheap ones. We use these in the remotes for our home smart lights. They have lasted two years so far with frequent usage. I think it is worth it to get the name brand lithium batteries if you are going to have a high usage application.
