Hi all any ideas as to why my leisure batteries go flat after one week I don’t have a solar panel and the batteries are new whe I plug in the Ehu it reads 12.4 volts but no amps many thank vespaman

I think you need to give us a bit more information. Make and year of vehicle and details of charging system and batteries would help. How are you measuring the 12.4 volts?

Also; are they disconnected or isolated and go flat?

Sounds like the EHU isn't charging them should read at least 13+ volts does it read better with the engine started
