2016 Lithium Battery, 4 Count (Pack of 1), Child Safety Features, Lithium Coin Battery for Key Fob, Car Remote, and other devices CR2016 3 Volt (3V) Cell

Update!!! During the coldest months of the winter the battery started working and has been working ever since! So these are the best batteries once they started to work! Put the new battery in my key fob and tried it out and it worked. Used it a few times that day but it hasn’t worked very well since! Once in a blue moon it will actually work! I thought being a Duracell battery that it would work better but it’s not! It doesn’t hold the power and it was a waste of money. It fit my key fob and was the correct number and size.

Bought this item for my Canon 40D for the date and time function as the camera stopped turning on altogether when the old battery dies. Great price and reputable brand.

These are great and have a good long life.

Why have the auto dealership replace the batteries in your remote and charge you $15-20 dollars. It's very simple to do it yourself open the remote and order the correct coin cell battery and save money

Great batteries long lasting

Batteries arrived earlier than expected! They were wrapped well in an envelope via first class mail. I always order Duracell batteries, so I’m expecting them to last a long time. Very pleased with JustCalculators.com

They were for my truck remote alarm. Perfect fit fast delivery and fresh

Ordered and came quickly. Just what I needed.

Good

Muito bom, qualidade excelente!

What can I say? Duracell makes great batteries.

Both of the batteries have no charge. I can confirm my device working properly with other battery and I have installed the newly battery at correct polarity. I have destroy the packaging to open them and feel waste of time to ask for return.
