820-3023-a shuts down on battery power.

[Sr. Robot]

Hi, got an 820-3023-a that shuts down on battery power. It doesn't do it if charger is connected (either with battery or without battery connected).

It has no visible corrosion, U7000 looks great.

Does it go off immediately when charger is disconnected?
If yes, check 3V42_G3H with battery alone.
