Battery Drainage
If you are unable to jump-start your car even with a portable jump starter, this means that your battery is completely dead. However, some additional steps might help you in the short run
Following are the additional steps you can take:
connections
First and foremost, check that the jump starter or jumper cable connections are securely attached to the battery terminals. Otherwise, loose or corroded connections can lead to a failure of power transfer.
Clean battery terminals
Properly inspect the battery terminals, because if it turned out to be corroded then it can greatly interfere with the flow of electricity. You can try to remove the corrosion by using a wire brush or a paste of baking soda and water to remove the corrosion.
Try a longer jump-start attempt
Do not rush the jump-start. At times, a completely drained battery may require a longer jump-start attempt. Therefore, keep the dead battery connected to the working vehicle battery for a little longer before attempting to start your car.
Replace the battery
The main reason for a failed jump-start might be a damaged battery. If the battery refuses to hold a charge, then this is a sign to replace your car battery. Typically, batteries have a limited lifespan and usually last 3 to 5 years. Therefore, if your car battery is over 3 years old, then it is time to change it.

Check the alternator and charging system
Sometimes, your battery is not at fault, but the alternator or charging system is. Even if your jump-start is successful, your battery may die again if it is not properly charged. In this scenario, have a car mechanic check the charging system and alternator to ensure their functionality.
Seek professional assistance
Your jump-start still failed even after trying all the steps mentioned above. This shows that you can no longer do anything, and it’s time to seek professional assistance. Either contact a reliable mechanic or a towing service to have your car taken to an auto repair shop for a detailed inspection
Conclusion
It is always a top priority to seek professional help. Remember, a dead battery can be caused by various issues, and it may be dangerous for you and your car if you attempt to self-diagnose it or entangle yourself in a complex electrical problem. Therefore, always have a reliable towing service number with you in times of need.
