scooba 390 suffered overload battery .

Postby gilmar1000 » November 26th, 2018, 4:21 pm

hello guys, I need your help, I have a scooba 390 and it suffered a battery overload.
Now when you plug the battery it blinks all the LEDs quickly once and does not turn on. If the charger is connected it charges normally.
but I noticed that when you wait several hours with it off and without battery, it works again for a few min.

I think it can be the two fets zxmp4a16. (Q41 and Q42)

Can you help me please?

thank you

Haven't experienced charging FET failure on the Scooba 3XX models. What is the stored voltage in your battery? How old is that pack? Have you performed a load test on the pack?

the battery in case is new and the problem occurred with the old battery ... I believe that it may be some capacitor failure because after a good time off it comes back to work ...
