PanasonicCR2032 3 Volt Lithium Coin Battery (20 Batteries)

Buying batteries online on Amazon is so much cheaper that it's a surprise, but a welcome one. I buy batteries online whenever I need them now, unless there's some emergency and I need them asap. So that it's not just my word for it, I looked up some evidence: price comparisons to show what I mean about how different the cost is. It's not meant to be a great guide -- just a quick example.CR2032, 3V Lithium, Coin Type Batteries:-------------------------------------------------------------------------Location ➜ # of Batteries ➜ Battery Brand = Price-------------------------------------------------------------------------Amazon ➜ 20 ➜ Panasonic = $6.67Office Depot ➜ 4 ➜ Duracell = $8.39Target ➜ 6 ➜ Energizer = $5.29Home Depot ➜ 24/4/4/4 ➜ ACDelco/Duracell/Energizer/Panther Power = $15.55 for ACDelco's 24-pk / $10.98 for each 4-pk for each other brand(Rounded) that comes to:33 cents per battery for Amazon-bought Panasonic batteries$2.10 or $2.75 per battery for Duracell at other stores88 cents or $2.75 per battery for Energizer at other stores65 cents per battery for ACDelco in a big pack at Home Depot, or paying $2.75 per battery there for for Panther Power.I'm not sure about battery longevity comparisons. As far as I know, there's no significant difference with 2032 lithium button batteries.I got these Panasonic batteries from a third-party seller ("Family photo"), fulfilled by Amazon (shipped from an Amazon facility.) They arrived on time, as described, were just fine. Popped 2 in my bathroom scale about a week ago, and the scale's been working fine since.One last AND VERY IMPORTANT note: swallowing a lithium button battery "can rapidly devolve and cause severe tissue injury in as little as two hours", or can kill a pet within 15 minutes, due to how current from the battery interacts with esophageal tissue. I hadn't known that until stumbling across the info recently. I figured a little PSA might be worth it, in case anyone else might not realize how little time there might be to react, too. Source for the pet info was petpoisonhelpline, article by Lynn R. Hovda, RPh, DVM, MS, DACVIM: "It has been estimated that only 15 minutes of esophageal contact with a 3-volt lithium battery results in significant and life threatening damage."🎄 🐈🐕With the holidays, it's very relevant: "the holiday season is associated with an increased number of pet exposures. Batteries are seemingly everywhere during this time of year, especially in decorations, electronics, and toys, giving dogs and cats unlimited access. In addition, visitors with hearing aids often leave these batteries loose on tables or bedside stands, forgetting that dogs and cats are attracted to them. Dogs tend to mouth and chew batteries while cats are more likely to bat them around in play. Left untouched, batteries aren’t harmful, and in fact, most swallowed batteries pass through the gastrointestinal tract without incident. If, however, a dog or cat damages one enough to cause leakage or swallows one intact and it becomes lodged or stuck in their esophagus the picture rapidly changes."

Fast and good price!

Purchased same year's back. Long shelf life good price, Great product

Oddly, Duracell batteries have a kid safe coating designed to deter children from tasting or swallowing these small batteries. While the intention is good, the coating interfered with the conductivity of the battery terminals and many devices don't function well.I purchased these to replace a pack of Duracells which were not working well in my devices and the result is good.

Best and longest lasting battery I’ve found for my Apple AirTags. Other off brand names I’ve tried last half as long or less.

What can I say. Best product. Fast shipping. There is no power source like Panasonic batteries. Recommended 100%

The Batteries are great, but do not buy Panasonic CR2032 3 Volt Lithium Coin Battery (20 Batteries)Sold by: Energy source because they will send a different item. Same battery but not the same individual packaging .i.e. you cannot tear off one battery in its packaging and put in your glovebox, suitcase, gun case etc...

Very happy with these batteries. All used have worked so far and an exceptionally low price per unit.When you need one, it’s nice to have 10 or more behind it.
