These batteries are well made. I've tried other brands that don't last as long and crust over time. I ONLY trust Energizer for my batteries needs!

These are batteries...

Had to buy one of these for our car key since the previous one was showing low battery. Don't see a big difference other than slightly better response when locking the car from door handle. I haven't noticed increase in range or anything

For device with small power use!

I always get these batteries for devices that draw little amounts of power. These do seem not last the longest. There is packs of 2 that you can get but by the time it's time to use the second one it isn't full battery anymore. It's why I buy them in packs of 1 only.

Excellent battery, good value for its cost, great performance, practical design and practical and reliable handling in any device with easy packaging and spectacular voltage. They give it a necessary current for the consumption of all devices.

This battery works great for the key fob for my vehicles. It lasts a long time. I use them for both of my vehicles! We've also used them in different remotes for household appliances for lighting.

Works for long periods of time, use it not only in my car key but also the same type battery for garage door remotes, probably have to change my battery once a year if that. Absolutely love it!
