Boosting a Dead Car Battery
If you are using a booster pack make sure you follow the directions so the polarity on the battery is not crossed which could lead to sparks! When the car turns over and the engine is running turn off all of the accessories inside the car including the radio and take the car for a long drive. If possible go on the highway and get the car up to cruising speed while keeping all of the accessories off. After driving for roughly an hour come back home, turn the car off and then wait 10-15 minutes before restarting it. If the engine starts then chances are quite high that your battery is old and needs to be replaced.
If the car did not start or it stalled while driving it then it would be a sign that the alternator is no longer working properly. The alternator converts mechanical energy into electrical energy to run all of the devices in the car while maintaining the batter. If you do require a new battery refer to your owner’s manual and purchase the right one. In the event, you need to replace the alternator it would be wise to bring the vehicle to a mechanic who can properly replace the alternator.
By troubleshooting the dead battery yourself it will help you save money on expensive automobile repairs.
