Stupid me...drained battery
Last night I was working on the '99 Expedition and left keys in ignition to roll down windows so I could refresh the black trim around the windows that fades so quickly. Well I went to bed and you guessed it, left the keys in and drained the battery completely dead. Is there anything wrong with just charging it back up with some highway driving for about 10 minutes or so. It is the OEM battery purchased new with car 3 years and 41,000 miles ago.

Give it a 2amp trickle charge or jump it and go driving on the highway for a bit. If the battery's "healthy" it shouldn't give you any trouble for a while. Otherwise, go to Sears or National Tire & Battery and pick up a DieHard GOLD (3 year full replacement warranty; 100 months prorated - jeez, working at NTB is damaging my brain!)

Did you shorten the overall life of the battery with this incident? Sure. How much? Who knows. Given that this battery is a little on the old side and winter is just a few months away, I would make a pre-emptive strike and get a new battery. Beat the line that will form during the first cold snap.

Actually it's not recommended to try and charge a dead battery with the alternator.
You are much better off using a battery charger.

Generally very good advice. . .
But mostly applies to standard passenger vehicles with 60-90 amp alternators. Completely drained batteries can pull more than 60 amps during the first 15 minutes of recharge, enough to fry a standard 60-90amp alternator. Trucks with alternators having a charging capacity of 120amps or greater usually suffer no deleterious effects from charging a dead battery.
