Also, unlike a standard Gas engine the DC-DC converter is something like $2k-$3k new whereas a new alternator can be had for $100-$200 from an auto parts store. You always want to pray that any electrical or charging system issues are the cause of a faulty battery and not the DC-DC converter. I have heard that the DC-DC converter is somewhat easy to replace though if it fails. That may save some labor $$$ at the dealership.
