Yes. The little box on the power cable houses a transformer, it will draw power at all time when plugged in even though the laptop is not plugged in. Same thing goes for chargers for batteries, R/C cars/toys, etc.  I got this information from my dad who is an arson and insurance fraud investigator. He spent about 3 weeks learning about electricity and electrical fires at FLETC (Federal Law Enforcement Training Center).

Yes. A battery draws what it needs from the charger, the charger does not force current into the battery. The voltage spec. is the same. Things would be different if you were to try to charge a five volt battery with a ten volt charger. You would probably blow the battery. Hope this helps.
