Charging (jump starting) batteries can potentially produce dangerous
amounts of hydrogen gas near the battery vents. BY conecting the negative
after the positive and removing the negative before the positive you can
always make and break the electric circuit with the negative jumper cable.
Usually when the circuit is made or broken there is a spark of some kind
and by connecting the negative cable AWAY from the battery therminal the
chance of exploding the hydrogen is reduced.
