It's not something I've encountered myself, but it is a 12 volt source. I do know the 12 volt system is separate from the hybrid high voltage system. I don't see anything obviously wrong or dangerous, the vehicle should handle the jump like it handles any other system draw.
I would suggest you have the hybrid running and AC on when you jump.
I wasn't talking about having the hybrid checked. I meant have the battery and charging system of the Honda with the bad battery checked. Sorry for being unclear.
..and 2 years is a long time to have a discharged battery. Expect to replace the battery, but a system check is always a good idea at time of replacement.
