What do you do with battery leaks?

Usually a battery will leak because of overvoltage, overtemperature or a bad battery cell. L series Saturns came equipped with a battery wrap which tended to cause the battery to overheat. The intent was to protect the rest of the engine compartment from any potential battey leaks, but the unwanted side effect was the heat. Remove the battery wrap and flush the entire area with baking soda mixed with water to remove all of the dried battery acid. Check the voltage when the engine is running. If it's much above 14 VDC at the battery, the voltage is boiling the acid right out. Have the battery tested. If one cell is shorted or damaged it can cause that or other cells to boil over.
