A normal 30 minute drive will probably put the charge you used to start the car back in, but I think it's marginal. Once the car is moving at 20mph+ the battery is being charged, so long as you don't have all that stuff working.
In order to charge a dead car battery, a set of jumper cables and a functional car with a charged battery is required. You will then have the ability to connect the batteries to one another using the jumper cables, and re-charge the dead battery by transferring energy from the functional battery.llow at least 5 minutes to pass after starting the engine of the car with the charged battery. This will allow the dead battery to build up a charge of its own, although it would take longer to fully charge the battery. 8.
