The battery is kept charged by a generator or magneto when the engine is running. It is located under the flywheel.
Most lawnmower batteries will be badly abused by this and it will be quite expensive in gasoline. A lawnmower battery will normally take 8 hrs (or so) to charge. Forcing them to charge faster, like off your car, will harm it.

Yes, it charges from the magneto.

If you are plugging in a battery charger connected to the battery, yes it will charge the battery. If you are referring to plugging in the block heater, then NO it will not charge the battery it will only warm the oil in the engine block.

Dead cell in the battery or something is on pulling power from the battery.

Answer Most of the time the battery is loosing charge on a mower it is bc the battery is going bad. The cells inside are wearing out and not holding a charge. Replace the battery and usually the problem stops. If it is a acid fillable battery then make sure the battery has the proper amount od distilled water and acid in it. Also if it is a serviceable battery then I would replace it with a maintenance free battery anyway. A lot less to mess with. Good luck.
