Every time you start your car, the battery provides a huge jolt of electricity that starts the engine. After that, your alternator recharges the battery. The length of time that it takes to fully charge your battery depends on the size and state of the battery, your driving style, and a number of other factors.
If you have a battery that is dead, it may take a while for it to get enough charge to start the vehicle again. This is why it is a good idea to leave your car running for a while after you jump-start it.
Yes, you do need to drive your car if your battery is dead. This is because your electrical systems will drain the battery while you aren't driving, so they won't be able to fully charge it.
When a battery is dead, it will not be able to fully charge the battery until you have driven it for at least 20 minutes. However, you should not be forced to drive for that long if you don't have any motivation to do so.
You can use a jump starter or a battery charger to recharge a dead car battery. This can help to prevent it from dying again soon. Just remember to make sure that you've connected the positive and negative cables correctly before trying to start it up again!
