Auxiliary battery charging issue

[Bensmithguitar]

I've been having trouble with my aux battery.  It runs fine for a while, then, I think what happens is the voltage of the battery drops low, and all sorts of warning lights etc come on.  My mechanic thinks the battery charging system isn't working properly.  Can anyone tell me whether the aux battery charges from an alternator or from the hybrid system?  Thanks

Hi, 

There are some posts on the Forum about Hybrid 12v battery- it is important to have the correct battery that incorporates start stop technology as a standard battery will ultimately fail as it did to me. Check out the other posts.
