How do I attach battery charger/maintainer under the hood

Forget "jumping" your car- you could do some very expensive damage- just take it to a good mechanic and get it repaired so it operates correctly- and get AAA to tow your car if it dies again- the days of jumping simple little machines are OVER- that ship done sailed-

That wasn't the question, but thanks anyway for the help. I was asking how to charge the battery without pulling the seat. I understand I can do this by connecting to the positive cable under the hood, and to a grounded area like a bolt on the engine block.
