The battery cables can spark if the cables are installed in the improper order. When attaching the battery cables, place the positive cable on first and then the ground cable. … Also, the ground, or negative cable, should not be touching anything metal while the positive cable is hooked up.
What happens if a car battery sparks?
Batteries emit hydrogen gas which is explosive. If you spark the battery, you can cause the battery to explode and that throws acid all over everything including YOU. Hook up the red cable to the positive of the good battery, then the other end of the red cable to the positive of the bad battery.
Is sparks from a car battery electric discharge?
When the battery is charged, oxyhydrogen, a mixture of hydrogen and oxygen, is produced in the battery. This mixture is explosive and can be ignited by a spark. An ignition spark can also occur due to electrostatic discharge.
Why does my battery keep sparking?
Any arcing is caused by amperage flow, slight arcing is normal. If you are getting excessive arcing when touching the – battery cable to ground or – post that means an electrical component in the system is powered on that should not be on or an electrical component or wire is shorted.
Is it normal for car battery to sparking when connecting?

Will a dead battery still spark?
If your battery is bad, it may cause sporadic sparks in the engine’s combustion chamber which lead to poor ignition of the fuel-air mixture. The result is more fuel accumulating in the engine combustion chamber which is then passed along partly combusted into the exhaust.
