BATTERY DISCHARGE / CASE DRAIN

Check for battery discharge (case drain) across the top of the battery using a digital voltmeter. Connect the negative (black) test lead to the battery's negative terminal post, and connect the positive (red) test lead to the top of the battery case. If the meter reads more than 0.5 volt, clean the case top using a solution of baking soda and water. Remove excess water from top of battery.
