Customer Ratings & Reviews

Always go with the Energizer brand as they are quality batteries, no matter what size. They have the longest running power as opposed to cheap batteries made elsewhere. You get what you pay for. Would buy again and would highly recommend.

Easy to use and lasts a long time. Should get several years worth for my car key.

The best battery I ever bought. Long live and quality

Much needed in problem crisis. Life Saver Needed it for my diabetic machine.

Good batteries.the batteries work very well. Good price

It's cheap. I bought it on sale but it work great like regular product.

Good price and battery. I use for my garage door opener. Last a long time. It's been years since I changed it.

Many uses for these batteries: air tags, security systems, watches, flashlights.

I used the batteries for my AirTags and work great.

Purchased to replace outdated batteries, as always energizer does not disappoint, durable, reliable w long lasting performance, at fraction of cost thanks to Best Buy deals!

All of your PC motherboards use this battery. It controls the CMOS configuration and feeds the real time clock of your PC. It is something that most people don't check or know about. There are other devices that use this battery. You might do well to check some of your other devices to see if they use it. I keep these batteries on hand because I have a fitness device that also uses it.

Excellent batteries to use in my key fob. Long lasting and reasonably priced.

Good battery life, similar to Duracells, but costs less. Best price vs. quality standpoint....

My push start car was not starting. It turns out the batteries in the remote were dead. It was 10 degrees below freezing outside & the windchill made it feel much colder. Thankfully I was parked in a lot that included a Best Buy store. I was able to walk into the store, purchase the batteries needed for the keyless remote, a store employee helped me switch out the batteries, & I was on my way home. Months later, the batteries I purchased are still working great.

Always an odd battery needed for the garage door opener.

From wall clocks to car keys, these are the most used batteries in any walks my life. The brand name says it all. Energizer/Duracell are the best ones in the segment. It lasts long, like really long ! You don't have to ever venture trying out other cheaper unreliable brands for the sake of few $$ that would defeat the very purpose of your purchase.

Received quickly and correctly as expected to have on hand for air tags.

They are batteries. They work. Not much else to say.

Fob said low battery, replaced with Energizer. Easy to install, works great!

Great use for my computers CMOS . Really did the trick
