Panasonic CR2016 3.0 Volt Long Lasting Lithium Coin Cell Batteries in Child Resistant, Standards Based Packaging, 10-Battery Pack

I don’t usually write reviews, but I felt compelled to share my experience with these Panasonic CR2016 batteries because they’ve saved me more than once.I bought them originally for a few key fobs and small electronics around the house that had been sitting dead for months. I’d tried off-brand batteries before and always ended up disappointed—either they arrived half-drained or died within weeks. These Panasonic ones? Completely different story. Every single one I’ve used so far has worked immediately and is still going strong months later.You can tell these are high quality just by the packaging too. The child-resistant design is a smart touch, especially for parents like me who are always on alert with little ones in the house. It’s reassuring to know I can safely store them without worrying about curious hands getting into dangerous things.Most of all, I appreciate how something so small just works—no fuss, no surprises, just dependable power. In a world full of stuff that breaks or disappoints, it’s nice to find something that simply does its job and does it well.Highly recommend.

Why did you pick this product vs others?:Good battery good price

I had been looking for the CR2016 batteries namely to be sold by Amazon and NOT third parties. Was glad to have found the Panasonic 10 pcs. Received them in original packaging genuine Panasonic product. I knew if I had ordered from Amazon directly they'd be the real thing. Already used 4 of them and they worked great. Way cheaper than the local stores and Amazon sells genuine button batteries. Avoid third party batteries like the plague. They are old expired counterfeit junk. Buy amazon directly.

Good quality battery seems to fit the need. Actually purchased the wrong size for my key FOB (needed the CR2032), and was going to return but that would have been a PITA.

Convenient to get here on Amazon since they aren't as common as CR2032's. I needed to have pairs of these for a mini-LED-flashlight. I checked the ones I opened and stabbed through the packaging to check the voltage on the rest and they all seem to have arrived fresh and in good condition. The flashlight is working well, and I have several sets of backups.

Good price.

As advertised

Good flat style batteries for my watch.
