If capacity and performance in cold weather are important, that means providing some way to insulate and heat the battery to keep it up to operating temperature.
Note that using a battery (both charging and discharging) will heat the battery because of the waste heat loss inherent in the inefficiencies of the charging/discharging process.
So you can charge your battery right before you leave in the morning to heat it up a bit, and then discharging it on the drive to work will add more heat. The real question is how long is it parked without being used and how fast does it drop in temperature. (This is where the insulation comes in....)
QuickCharging / Supercharging will heat up the battery faster/more than a regular L2 charger or trickle charger.
