Battery Charger specifications

[javo16]

Hello,
Can someone please help me with the technical specifications of the battery charger of Robotino 2?
I lost mine and I don't know how to replace it or if I can use a generic battery charger.
I think it can't be generic since it also can power the Robotino solely.
I guess it has something to do with the robot electrical specifications but the manuals doesn't show it.

Please, any answer or suggestion is welcome.

Thanks in advance

You can use any 12V Lead-battery charger. It should be powerful enough. Maybe 3A charging current.

Or is it 24V? What voltage is a single battery? Both batteries are charger at once so the charger must be twice voltage of a single battery.
