When you say that something (that's not subatomic) has a charge, in practice it means this object has a lack/abundance of electrons. A macroscopic object rarely can be charged, when it happens, then it tries to get rid of it as soon as possible and discharge. It's when you feel a little electric shock when you touch a doorknob or something.
Now this would mean, if a battery had a net charge, then you would probably die from touching just one of the contacts. This obviously doesn't happen.
Now how does a battery work? Traditionally 2 different metal pieces of different electrode potentials are immersed in liquids of their respective cations. So one is more easily oxidized than the other and therefore the metal atoms lose some electrons and bla bla basic high school example. Charge doesn't pull current, because the current is the movement of charge, the battery doesn't have a net charge, it just moves the electrons from one metal to the other. Voltage pulls current, which is just the difference in electric potentials between the points, which is basically an energy difference which is needed to move the charged particles.
Now when you 'charge' a battery you provide the energy required to reverse the redox reactions and now the metal which would get reduced in a normal spontaneous reaction, is oxidized and vice versa and thus you store the electrical energy you would later use.
