Leisure battery gone flat

7.2K views 37 replies 16 participants last post by  barryd  
Forgive my ignorance concerning all things electric, especially batteries, I would like to know if it is completely safe to leave the van on EHU for 24/7. If so how much juice is being used. I have a bog standard LB with no fancy attachments ( no idea what a MPPT is) which doesn't hold a charge for more than 48 hrs or so. The VB only charges when the engine is running. Any answers much appreciated. Trev
