Can you jump start car with bad battery?
If you’re stuck with a dead battery, you can start the car by using jumper cables to connect the bad battery to a fully charged one, whether or not it’s fitted to another vehicle.
Can a car battery be too dead to jump start?
There is probably nothing worse than a dead car battery amid your possessions—at least, among your battery items, anyway. YES, a car battery can get so dead it will not receive a jump start anymore.
Why does my car not start with jumper cables?
If they are damaged or corroded badly, they can prevent proper amperage draw for the starter. Since you said it starts with jumper cables, it is most likely a bad battery. As CharlieRB pointed out, just because the lights come on doesn’t mean the battery is ok.
Why does my car battery not work when I start it?
Starting the car is the single hardest thing (draws a lot of amperage) for the battery to do. If it is becoming weak, it will become harder and harder for it to crank the engine. The lights and other accessories may still work because they draw less amperage (which the battery can still support).
Why does my car not start when I turn it off?
It is possible that your battery is bad and will not take a charge from your alternator while driving. In that case every time you shut your car off you will not have enough juice to start it again. Inspect your battery – it should have at least 12.5 to 13 volts to start your car, if it doesn’t you will need to replace the battery.

Why is the battery on my JumpStart not working?
It will not last forever. At some point, usually between the three-year and five-year mark from new, your battery will wear out and need replacing. Another possible cause is a defective cell or a short circuit within the battery.
What should I do if my car JumpStart does not match?
If they do not match, serious damage can occur to both vehicles. Park the cars close enough for the cables to reach, but they should not touch. Turn the engine off in the car with the good battery. Unplug any accessories (like cell phone chargers); the power surge generated by the jumpstart can short them out.
Why does my car not start after charging?
In cases where the battery is extremely weak, trying to start the vehicle immediately after connecting the cables may not provide enough energy to start the car. By allowing the dead battery to charge up, you increase the chances the vehicle will start.
