They don't loose their charge in cold weather. The voltage drops. The amps are still there.
With lithium batteries being so much lighter, you can keep the voltage the same, but increase amps in the same demensions. A higher amp battery will produce a higher voltage under load compared to a battery with a lower amp rating. So it might be very well possible that a lithium car battery would perform better in colder conditions being that it has a higher voltage output due to a higher amp rating.
I'll say this. I don't believe MB would be installing these in cars if they were unusable in colder climates.
