Default Re: Jump Starting?

When a battery is fully charged, it will start producing Oxygen and hydrogen gas.
from the water in the battery (H2O);and that gas mix is very explosive.

Thats the reason you always connect the positive post's on the two batteries.
and then connect the last Connection to Earth somewhere on the Engine or body.
Not on the battery post, preventing to get at spark igniting the explosive gas.

This is for a car with Negative Earth.

Avoiding sparks is the name of the game.

I have started 6 Volt cars with 12 Volt and even with 24Volt. and used the method above.

Keeping the Connection time as short as possible helps.
