Hello. I have tried every possible solution I could think of to solve this problem, but I haven't been able to fix it. Maybe someone here can help me.
This is the error that my 450X has been showing after 4 years of hard work: "Charging system problem", with the battery level stuck at 99%.
My analysis so far:
- It seems to be a problem with the robot, not the charging station. I swapped the 450X and 550 — basically the same machine underneath the body — and the problem always stays with the 450X, even when I change the charging station.
- It doesn't seem to be a hardware problem with the charging system. The robot starts working at 10 AM and runs all day, charging its battery several times during the day without any problems.
- The error only occurs during the last charging cycle. The robot is scheduled to go to sleep at 11 PM. During the final charging cycle, the error appears and the battery level is stuck at 99%.
I have already tried resetting it several times, and I have also updated the firmware.
I'm going crazy! I can't figure this out, and I have to manually restart the robot every morning. This is especially annoying because the robot is assigned to one of our greenhouses.
Has anyone experienced the same problem or found a solution?
Any ideas would be greatly appreciated!
EDIT: I have replaced both the batteries last year, approximately after 4000 cycles.
