Once the battery has come voltage in it you can remove the jumper cables and charge it the rest of the way on its own .
My workaround was to hook the charger ends to a voltmeter that was in the ohm resistance setting. This triggered it on, then I put it on the battery. I have NO idea the underlying mechanics behind this though, all I know is that it worked.
