Officially:

You should only ever start the car from an external fully-charged battery freestanding next to it.

This will ensure that at no point during the process will your car electrics be exposed to voltage spikes.

Starting a car from a battery fitted in another car may damage components in the CANBUS or SAM modules on either car.

Said that, many people use the old fashion method of having two cars next to each other, or using a JumpStart charger, and get away with. I guess the question is how lucky you feel...

But ultimately the solution is to find and fix the source of the electrical drain on your car.

Even if your trip to work is short, you should not need jump-starting as long as the car has a good battery and the alternator is working properly.

If the battery went flat because of short trips, jump-starting would not help much to get the battery charged. What ever you plan to do to charge the battery after the jump-start, do it before you need jump-starting in the first place.

Battery usually runs flat if the car has a fault (high quiescent current etc.) or if a fuel based standalone auxiliary heater was used extensively at -20 degrees Celsius, which should not be your concern.

Never jump start from another car. Only from a jump pack.
