Yes. Cold weather can deplete the charge in any motorcycle, marine, or automotive battery.
Your putting a charge on the battery when its running.
Weak battery not holding a full charge or alternator not supplying a suffient charge to the battery - check with a voltmeter A fully charged battery should read approx. 12.8 without engine running Approx. 13.8-14.2 with engine running
A fully charged car battery will read 12.6 volts, 75% charge will read 12.4 volts, 50% charge will read 12.2 volts, and a 25% charged battery will read 12.0 volts with the engine not running. With the engine running it will read 13.5 to 15.5 volts.
Age of battery Battery will not hold a charge (check with a volt meter) A fully charged battery should read approx. 12.8 volts (without engine running) If charging system is working properly reading should increase to approx. 13.8-14.2 with engine running. If voltage does not increase with engine running could be a problem with charging system of battery is defective and will not take or hold a charge
You can start a car without a battery if you hook up a jump pack or use jumper camples but it could fry your alternator. It is pointless to charge a car without a battery. When you charge the car you are charging the battery.

The computer's power, or its ability to stay powered on and running, is maintained by the charge in the battery. The battery's electricity is used by the computer to keep running. If there is no charge in the battery, or the battery is removed, the computer will shut off and will not be able to be powered up.
By running the engine on the vehicle or by connecting the battery to a 12 volt battery charger.
Yes, a cellphone can be charged, with the proper adaptor, without a vehicle's engine running. The electrical current [measured and refered to in Amps, usually milliamps] required is well within the capacity of a vehicle battery in good condition and charge.
