PKCELL CR2477 Battery 3V Lithium Battery Button Coin Cell Batteries(100PCS)

Great value package

IF you need a LOT of these this is a good price per battery for sure. Ships as four sheets of ten batteries. The package had a very strong smell inside, so keep that in mind storing these as they made the drawer I have them in smell too. I'm not sure what's causing it.The few I've used so far work and haven't died early. All of them seem to be intact.

This pack of CR2477 batteries is a great value. The batteries work as well as name brands and have had no issue with them. Have used them in remotes as well as other electronics like a welding helmet and all have lasted.

I bought these in June, first battery I used didn’t last long so I started writing down when I was using them. Two of them lasted about a month, one lasted about 3 months and the last two were 5 and 3 days. I have now moved to the second packet, let’s see how long this one lasts.

Great value for the money and seems to last for a long time.

Wireless devices require constant upkeep and one of the main things that need upkeep is the replacement of batteries. Batteries aren't exactly cheap as they are constantly consumed. Rechargeable batteries aren't any better as they don't store as much energy and need to be recharged more often. The PKCell CR2477 3 volt lithium button batteries I ordered seem to do a good job in keeping my Arlo Security Sensors up and running. The batteries seem sturdy and built well. I measured the voltage on a sampling of them and they all measured a little bit above 3 volt, which is great as that indicates to me that they are somewhat fresh and have not degraded over on a shelf for a long time. One of the best things about these PKCell batteries is how affordable they are compared to the name brand ones like Panasonic. I ordered a pack of 10 batteries and they came nicely packaged in two blister pack strips enclosed in a padded envelope for protection. This pack of 10 batteries cost me less than ten dollars. if I were to buy the name brand battery, I would have only gotten maybe two or three batteries as opposed to these ten. Great deal! Time will tell how well these batteries will hold out compared to name brands.

The CR2477 is a larger form factor "coin" battery mainly used in monitor cameras, remote audio equipment, and other devices that require significant power reserves. It is thicker and wider than the much more common 2032, but it holds more power and remains useful for a much longer time.These batteries meet all the right specs of a 2477 on paper; I hope they perform as advertised. Does anyone rmember when coin batteries were hard to find? Thankfully we no longer have to hunt for them, and they generally cost musch less than they did even five years ago.I've got devices that are on 24/7 and need a battery like this. Looking forward to their longevity and performance.

I have a few smart home sensors (Door/window sensors) that use this size battery. After installing, the battery reading I got was that it was 100%, as expected. The sensors chew up batteries when used continually and holds charge if it is rarely used, so your mileage may vary. I would say that the sizing is correct and the charge was full when installed. This is a nice quantity of CR2477 batteries to restock my need for my smart home sensors.

Not what I wanted. Still need to return them.
