Does the charging take place before the jump start?
If your car does start, let it run for a few minutes to help charge the battery further. Be sure to drive your car for about 30 minutes before stopping again so the battery can continue to charge. Otherwise, you might need another jump start.
When do you need to jump start an electric car?
You may need to jump start an electric car if its batteries have been completely drained. The lithium-ion batteries may not be able to be recharged unless the vehicle is jump-started via the 12-volt system, allowing the electronics to operate first.
What happens when you jump start a car battery?
Reverse polarity — This might be the scenario when you car is battery down and you are trying to jump start an ECU. Always c onnect the positive leads of both batteries first, then the negative leads. This will ‘soften’ the flow of power through the earthing system and prevent power surges or spikes.
What should I know before jumping my car?
Another vehicle that has a fully charged battery that is the same voltage as the car being jumped. Read your owner’s manual before attempting a jumpstart. Newer cars often have jumpstart lugs where the cables need to be attached, instead of directly to the battery terminals.
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.

What happens to the battery when you jump start a car?
What is happening is a charge is actually flowing back into the jump starter battery and giving it more power than it was meant to handle at one time. Thereby causing damage to the battery. Secondly, the process of jump starting a car can cause wear and tear on the battery of a jump starter.
