I have an led pir light.
Two rechargeable batteries voltage measures 3.05 & 4.52 so I'm guess 1 battery is not charging.
The dimensions are 18mm dia & 78mm long approx.
When I search to find the battery type, on Wikipedia, I reckon is battery '18650', when I search to buy this battery it says its 3.7v.
Any help appreciated.
Thanks
