About jumping car - Connection Negative

I don't know if it is true or not,but I once read that Positive is
really Negative and Negavite is really Positive.Maybe the Brits have it
right?
Visit a scrap metal yard once in a while where they buy old car
batteries and you will probally see some batteries that have blown up,it
isn't a pretty sight.When jumping another car battery,if you cover both
batteries with a damp cloth,that is suppose to lessen the chance of a
battery exploding.And be carefull when carrying a battery in your
hands,just letting a battery drop on a hard surface can cause it to
explode.

Electron flow is from negative to positive. But current flow is whatever
you want it to be. The sign is arbitrary.

The reason electron flow is counter to the standard notion of current
flow is mostly because Ben Franklin made a guess about charge migration
and the guess turned out to be wrong. Oh, well. It's a couple centuries
too late to worry about it now.

Because if there's a spark, when attaching the negative cable...a better
chance that the battery won't blow up!!
