2 Packs 6040mAh Replacement Battery Compatible with Ring- Doorbell Camera 2/3/4, Spotlight Camera, 3.65V Rechargeable Upgraded Lithium-ion Batteries Quick Release

Somehow I lost my battery for the Ring 2. I got my replacement in just two days. Everything worked out great.

These are a great deal. Any time I get a notice that my battery is low I just swap them out in my ring door bell. I wish I would have purchased them earlier

I'm an electronic designer and I found that these particular batteries are not recognized by many Ring devices, including the charger and the newer spotlight cams. The Ring batteries have 5 terminals, the two outside terminals are direct battery connections and the three middle terminals on a true Ring battery have a definitive resistance/voltage value that might come from an internal thermistor circuit. The Ring charger can display an "over temperature" error condition, suggesting that a temperature measuring circuit is in the battery.The middle three terminals terminals on these particular "equivalent batteries" are either floating or connected to an arbitrary high resistance.It looks like the Ring devices look for particular connections on the three middle contacts and baulk when they are not there. Can't really blame them.

Performs as expected

It took two times for the camera to regester that it was there, however, now that it's there, I only have to change the battery every 2 months, well worth it for less hassle.

Works like they are supposed to! Yay!

Shipping was fast. They came ready to use on ring camera

I purchased 2 of these for my spotlight cam, when installed the camera did not recognize them, no matter what you do it will not work, they dont match the RING model number and do not fit firmly in the cameras, they do not speak the same electronic language that Ring cameras do, make sure you get batteries that have RING name printed on the batteries or you may be wasting time and money and frustration!
