Car Battery

Car i charge a car battery with a charger when it is still connected to my car?

Ok i know this is a dumb question but i am totally clueless when it comes to cars!my battery is flat - i cannot get it to start with jumps leads so the only option is to charge it with a battery charger which i have. now, i cannot take the battery out so is it possible to charge the battery without disconnecting it from the car?thanks in advance!
Answer
Yea, red is positive, black is negitive just hook er up and let er rip, once the car starts unhook it and let the car run for like ten minutes and the alternater should charge the battery (alternater is a generator that uses the engines power to run electricity through your car), which is why your cars battery never dies while your driving
