Likely you suffered a hydrogen explosion by improperly hooking up the cables.Did you hook up the ground cable on the charging vehicle last? It is always prudent to make no final connections next to a battery - the last one should be to ground on the charging car's engine frame or engine, away from the battery. Otherwise you can get a spark and explosion..... Why was the battery flat? You need to have the system checked, even if it is merely to reassure you that the alternator is ok. If you spill battery acid, a water flush probably is NOT enough to completely get rid of the acid. You need to mix up a BIG bucket of baking soda and water and apply it liberally wherever the acid could have splashed. If you see any fizzing, then there is still acid left. If you do not remove (neutralize) all the acid, you may have very serious corrosion problems later to body and engine parts. I hope you were not hurt - were you wearing safety glasses? Good luck, and take care of this very quickly! John Davies Monroe WA USA 2001 Saab 9-5 Aero Wagon 2000 Audi A4 quattro 1.8T 1991 Jeep Cherokee Laredo 4x4
