Review on Set Of Two High-Capacity 2560MAh Replacement Batteries For Arlo Pro/Pro 2 Cameras - Rechargeable With Up To 2 Months Of Life Per Charge - Simple To Install And Use by Casey Oliver

I prefer to use the name brand batteries for electronics, at least when the type is proprietary. However, in the case or the Arlo camera batteries, I have found zero Arlo ones that are actually from them; however, I have found some second source batteries that sport the Arlo name on the case, but not on the label.I don't know if this confirms endorsement by Arlo, or if it was just a copyright ripoff by some other manufacturer. My experience with THOSE was less than exemplary, since while they initially charged well, and seemed to work well in the camera, I started to get many instances of those new ones failing to be recognized by the legitimate Arlo charger, and thus could not be recharged, AND those that still could be recharged were not lasting nearly as long in the cameras as even the old Arlo batteries that I still had and was still using. It was apparent that the new ones, although pretty on the outside, were not the same on the inside.Now, I have purchased a pair of these 'upgraded' Rapthor 'Arlo' batteries. As with the earlier ones, they look like a nice, quality product on the outside. I immediately noticed that the recessed battery contacts seemed deeper than on my originals. While they were recognized by my Arlo charger, and seemed to take a charge without trouble, I had a heck of a time getting them OUT of the charger. To explain, the batteries insert fully into a rectangular socket on the charger (which can charge two batteries at once), then push them again to activate a spring eject mechanism. These new Rapthor batteries appear to be just a little bit larger than the originals, and thus they stick in the charger sockets, and the spring ejector is not strong enough to push them out. I had to laboriously tap the charger on the side of a table until the Rapthor batteries finally inched out of the sockets. Then, when I put them in the cameras, the camera failed to recognize that I had put new batteries in them.no lights came on. After removing and reinserting the batteries on the camera(s), they finally started to work. This might have had something to do with the deeper inset of the contacts.The jury is still out on how long these Rapthors work in actual use.UPDATE November 2021. Based on my experience with two of these Rapthor batteries, I will be discontinuing their use. They seem to charge to the satisfaction of the Arlo brand charger, but since they are oversized, they stick in the charger and and very difficult to get out. And where all of my Arlo cameras, when using the original Arlo batteries, usually got at least a couple months out of a freshly charged battery before complaining of 'low charge', these Rapthors are, at best, getting only one month. And, since they ALSO get stuck inside the cameras, I have to use superhuman means to extract them. I don't think these Rapthors are anything like the original Arlo batteries on the inside, and Rapthor could not even be bothered to manufacture them with the correct case dimensions. I will be looking elsewhere for Arlo batteries, and I am downgrading my review to one star only.
