spill cleanup-new keyboard, not charging, taken to genius bar.

Son spilled coke on keyboard. Cleaned best he could, keyboard and touchpad not responding correctly. Touch pad right button on constantly. Son replaced keyboard, everything working except does not charge. No light on magsafe connector. Took to Genius bar. Told me minimal power to Logic board and hard drive. Would boot up, but battery at 7%. Tried one of their chargers, but no light with theirs either. Was told it was probably the logic board, $475.00 plus tax. Came here, bought logic board, still no joy. No light on charge plug, battery status blinking on last LED, no battery power and not charging. HELP

Cannot download anything, as there is not enough power left in battery to boot up. Any way to charge battery directly?
