I’ve been having similar battery charging problems as everyone above. -> email that battery is almost out*** I went ahead and also bought the solar panels since I was frustrated about troubleshooting the proper power from the regular door bell system. So when I installed the solar panel and it didn’t work I was really upset!!! With the solar panel I noticed that when I plug ring into solar panel and don’t mount it; it charges. However, when I mount it in the solar charger mount something shorts out and it no longer charges….. Fix: sooo put some electrical tape (actual a little thicker tape with backing) on the ring metal connectors and plugged in and started charging off the solar. Mounted it and since it is not shorting out on metal contacts continues to charge. Problem solved and didn’t have to replace the battery!!!!! Happy so far.
