This topic was closed after several years… With NO APPARENT SOLUTION…
What I have found is that ONLY RING BATTERIES for the Stick Up Cam 3rd Generation will work.
The replacement Batteries will not work (other than Ring Products)… (They work on all of the other Ring devices, but it appears not with this product)
I have solved this issue with my 3rd Gen by only using Ring Batteries.
Hope this helps… as they closed this with the standard solutions which DO NOT WORK…
