Leisure battery

[ne25man]

I’m just about to pull the trigger on a beautiful 2020 300 AMG, could someone please tell me how I can check the health of the leisure battery?
Thanks so much

Check if the roof will raise and lower ok that indicates enough ooomph in the unit !

The control panel also indicates the LB volts- mine normally sits at about 12.7 but raises to 14ish when the engine starts
