Sorry to hear that you got stranded. Hopefully they will put your battery on a charger while installing the alternator. If you unlocked your OBC, keep an eye on the battery's voltage because once it's been deeply discharged as it is permanently damaged and may not recover, or have difficulty keeping a charge....and you may find yourself needing a jump after spending the money for a new alternator.

Just remember to check the battery BEFORE starting the engine, or a few hours after shutting down so that there isn't a "surface charge" on the battery...which will not really give you an accurate indication of its health.

Good luck.
