Check the battery and connection points
Confirm the battery is not leaking, swollen, or damaged. Use the jump points and connection order in your vehicle manual.
Choose your starting option
Match a portable jump starter to your engine size and battery voltage, or use suitable jumper cables with a donor vehicle. Follow the instructions supplied with the equipment.
Check the battery after recovery
Once you are moving again, fully recharge and test the battery. A maintainer suits a car that sits; a battery tester helps check battery condition when the problem keeps returning.

Useful answers before you choose
Should I buy a jump starter or a charger first?
Buy for the job you have. A jump starter helps when you need the car running immediately, while a smart charger is better for slowly recovering and maintaining a weak battery.
When should I stop trying to start the car?
Stop if you smell burning, see swollen battery sides, notice damaged cables, or the vehicle behaves unpredictably. Those are signs to use roadside assistance or a qualified technician.
Can repeated jump starts damage electronics?
Unsafe jump starts can create risk, especially on modern vehicles. Use the vehicle manual, correct polarity, and a tool with protection features when possible.
Can you drive a car with a dead battery after a jump start?
You may be able to drive after a successful jump start, but the battery is not fixed. Drive only if the car runs normally and the location is safe, then charge and test the battery before relying on it.
