Review on IMah Rechargeable Battery Pack For Ring Stick Up Cam, Spotlight Cam, Video Doorbell 2/3/4/3Plus And 5F53E9 V4 - Compatible With 2Nd & 3Rd Gen - 1-Pack by Vincent Lott

I have two Ring doorbells and wanted to have an extra battery so I could have one charged and ready to replace one that's in service when it gets low and decided to try this one.The battery looks exactly like the original Ring battery. I charged up nicely in about the same time it takes to charge the Ring, with the LED lights on the front telling you when it's full.It fit perfectly into my Ring doorbell and even with the cold and temperatures going below freezing, it's holding it's charge.At about half the price of the name brand battery for equal performance, this is a great buy and worth getting.
