Here's why:
* Jump-starting provides a temporary boost: Jump-starting uses another car's battery to provide enough power to start the engine. It doesn't actually charge the dead battery.
* Charging requires a charging system: A car battery needs to be charged by the alternator (part of the car's charging system) while the engine is running.
Here's what you should do if your battery is dead:
1. Jump-start the car: Use jumper cables to start the car, but only drive it to a safe place to get the battery checked or charged.
2. Take it to a mechanic or auto parts store: They can test the battery and determine if it needs replacement or can be charged.
Note: It's best to avoid driving long distances after a jump-start as the battery might not have enough charge to handle the load.
