Battery not holding charge

[MDS730]

I’ve had the Ultra 2 cameras for about four months. They were down to low 60% battery so I decided to charge them at the end of the year.  I removed from their mounts and charged all 4 to 100%, blue light on solid on the camera.  I was very careful to put each camera back in the exact same spot.  1 week later and they are all 4 at 5%.  There has been no motion detected for the week and nothing has changed with Wi-Fi signal, etc.  any ideas on why they are not holding a charge this time?

Could be lots of things, including a change in signal strength and/or quality (new 2.4GHz devices nearby or have been moved?) as well as the total number of recording times and live viewing. You may need to deactivate Smart on the cameras so you can get an accurate count of the total recording times (Smart still records but then can discard the video).
