Red battery light on intermittently sl550-07
Dear mB world members.
The red battery light ( front battery not charging) is coming up after about 15 min. Or what I expect when the engine bay is hot. First start of the day has no problem for the first 15 min. Then if standing outside when over 70° f it will illuminate instantly. Both battery’s has been replaced.
any idea? Or most likely the N82/1 box 😪?

No silver bullet for this, as it could be a number of things.
I would suggest you read this entire thread as a primer. Others may jump in with more specific diagnostic questions for you.
