I have to sell my car. Not fun, but necessary. When the battery died, I replaced it, and three days later it went kaput. I got the alternator replaced, but it blew out. So did the second and third. The fourth never got hooked up, and wiring problems were discovered.
So I got the battery charged, and drove the car to where I’m selling from. A charge lasts about 3 days, since the alternator isn’t hooked up.
I’ve had an offer (yes, I told the prospective buyer what’s wrong with it and how much the parts should cost), and realised that the battery may have drained.
So my question is: How can I recharge a battery that won’t hold a charge…without a battery charger? Is it possible to jump-start it, and let the car I’m jumping from run for 20 minutes or so? Or does battery charging not work that way?
