I've had to do this many times with no problems when the battery goes flat after long term left standing. I use jump leads from another car alonside.

P.S If you read the codes after a flat battery you may find lots of apparently spurious DTCs such as door locks, mirrors etc. If you just clear them and reset your seat and mirror memory positions everything should be OK going forward.

P.P.S. The whine from the alternator may, and I stress may, be because of a very high charging load in trying to support a failing battery, however, keep monitoring it and if it returns get it looked at.
