Just to update the good folks on this thread.
This is day two with the Ring solar panel working as it use to.
Once again this morning my test Stickup Cam was at 96%, four hours later, it had charged to 100% and holding.
I just put freshly charged batteries into my other three solar powered Stickup cams. Will update everyone on Monday how they are holding/charging.
For those of you that are still having charging issues. Make sure to charge your batteries to 100% and then install back into your cams. It is much harder to charge these types of batteries from 10% to 15% than it is to charge from 90% to 100%.
