I got to thinking while boosting my lawnmower’s battery. It is my understanding that the electrons leave the battery from the negative pole and enter back in via the positive pole to close the circuit. I just never understood why the 2 negative terminals were connected to each other and not to the opposite charge when performing a “boost”. If the dead battery needs energy, why not plug the good battery Negative to the bad batteriy Positive to “feed it”?
I can’t make sense of two batteries both having their negative going to one another…
My nose is bleeding. Help. Thanks!

You’re not putting energy into the dead battery, you’re using the good battery to start the engine. Think of it as taking the dead battery out and replacing it with the good one.
