Thanks for the alternator current of 100 Amperes and 1200 Watts -- I didn't have that data! If I run the battery down, then I'll just have to wait until the electric utility restores the power! Then I'll have to recharge the battery! For that, I do have a battery charger. Curiously, the battery charger puts out only 14 Amperes!!! The charger and a lot on this whole subject has lots of warnings about how fast should charge a car battery -- their advice is to charge slowly or damage the battery, ..., explosions, etc.!!! Ah, they didn't get to college like I did: Had an old Chevy, stick shift. Somehow, too often, when I tried to drive to college for the first class, the battery was dead. Hmm .... Well, the driveway went downhill a little to the street. Sooo, with the door to the driver's side open, I stood by the steering wheel and got the car rolling rolling backwards downhill -- jumped in, closed the door, and aimed the car in the downhill direction on the street. Again with the driver's door open, with the transmission in neutral, got the car rolling downhill, reached in, swatted the shift lever down to engage 3rd, High gear, kept pushing, and right away the engine tried to start but, with 3rd engaged, struggled. I jumped in, pushed down on the clutch, put the shift into Neutral, gave some gas, pulled the door shut, and drove to class! After about the 15 minutes of driving to class, the battery was nicely enough charged to start the engine -- the dead battery problem was solved until the next dead battery problem! Lesson 1: If listen to the usual rules of safe operation of a car, won't get to class on time! Lesson 2: Can give a battery a nice charge quickly, e.g., 15 minutes! Another issue: At one point I did discover that the battery charger won't do any charging at all for a fully dead battery. So, I just got a laboratory style DC power supply and used it to give the dead battery an initial charge and then used the charger intended and finished charging.
