In fact, this morning I've used the A118 as if there was no problem (27°C outside).
The battery has charged during driving, about 3 hours with some pauses.
During this time, the camera has worked properly, no files were corrupted at each car stop.
Then, I have unplugged the camera, started it without external power, and started recording with screen ON (no screensaver)
The battery has lasted exactly
29 minutes, and the camera has shutdown.
In fact, it is great that this camera has survived to overheating conditions.
Remember that when the battery was empty, the camera was still working correctly, has only corrupted each last file at car stop.
So, when overheating, the camera has still recorded, but not charged the battery at all, because of overheat for a long time.
I had placed the camera at the rear of my Kangoo, as shown on the last video review.
This zone of the car has no air conditioned, so it was very hot inside.
As a conclusion, I just have to say that the A118 has passed the overheating test with success
Sorry again to have pointed out a non-issue.
A118 is just perfect !
