I'm not sure what you're asking but maybe its this: Red is Positive (+) and Black is Negative (-).
To charge a dead car battery, you'll need a compatible battery charger or jumper cables and another vehicle with a working battery. If using a battery charger, connect the positive terminal of the charger to the dead battery’s positive terminal and the negative terminal to a grounded metal point on the car. If jump-starting, connect the positive terminals of both batteries first, followed by the negative terminal of the working battery to the dead battery's negative terminal. Allow the dead battery to charge for a sufficient time before attempting to start the vehicle.
Put the solar panel in the sun;Attach the red wire of the panel to the positive terminal of the battery;Attach the black wire of the panel to the negative terminal.
Hook a jumper cable from the positive end of the donor car to the positive terminal of the Charger, hook a jumper from the negative terminal of the donor car to a spot where you can make ground on the Charger, and have at it. The battery is in the trunk, and there are jump start posts under the hood on the passenger side.
A trickle charger is a car battery charger that is designed to be left on a car for very long periods of time to re-charge that car battery by slowly adding charge to the battery.
To connect a battery charger to a Citroën Xsara Picasso, first ensure the car is turned off and the charger is unplugged. Attach the positive (red) clamp of the charger to the positive terminal of the battery, then connect the negative (black) clamp to a suitable ground point on the vehicle or the negative terminal of the battery. Once connected, plug in and turn on the charger, following the manufacturer's instructions. After charging is complete, disconnect the clamps in reverse order: negative first, then positive.

wth a charger
Sorry, but that is not likely to work. Both the voltage and amperage provided by a charger for a laptop battery will not be correct for a car battery. It is likely that you will damage the charger.
A battery charger does one thing. It charges a battery, and starts with whatever charge is in the battery and goes from there. Running an automobile battery down will shorten it's life.
No, you can charge the battery while it's in the car.
