20 Energizer CR1632 3 Volt Lithium Coin Batteries

It's a flat battery. Why do you need a flat battery? I'll tell you why. This. Can't get away with a car with a car key without one of these. Woo hoo thanks

I use this battery on my cars key FOB. Fits perfectly, battery lasts for years between replacement. With the ability to last for years you know it has good build quality with a strong initial charge with the ability to hold the proper voltage even after extended usage. Being small and inexpensive to the size, you can feel good knowing youre not spending much on a disposable battery.

We bought these batteries last summer for our kids' watches, and they've been great! They fit both types of watches without any issues. What really impressed me is that they're still working after all this time! We haven't had to replace them yet, so I'd definitely recommend these if you're looking for long-lasting batteries.

Batteries in general are getting more expensive and these ones are no exceptions. Most of the things that require these batteries always seem to need more than one and they don't seem to last very long. It's neither better or worse than other brands in the same category.

The Energizer 1632 Lithium Coin Battery is a reliable, long-lasting power source perfect for small electronics like car key fobs, watches, and heart rate monitors. Performance: Delivers consistent 3V power and holds a charge well in storage. Fit & Compatibility: Standard 1632 size fits smoothly into specialized compartments without connection issues. Pros: Trusted brand reliability, long shelf life, child-resistant packaging. Cons: Slightly pricier than off-brand multi-packs, but worth it for the peace of mind.

great batteries the best long lasting for my car they actually work and they last longer than they even say im super impressed and they will be the only batteries i ever use

They're really good for when I put them into my car keys, they last a long time, and overall perfect for when you need a quick change of any of your items that use these batteries.

Good quality battery with a long life. Use them on my alarm sensors and I have never had a failure or any type of leakage from the batteries themselves.

The batteries worked really well and lasted a while. I used them in my every day live without realizing it. They help power things I need throughout the day like my car keys and portable lights to read or see in the dark
