How to quickly perform a parasitic draw test and and identify the source of the drain. NO START!!!

ALL vehicles draw some power from their batteries when the car is shut off. Vehicles with onboard computers have Random Access Memory (RAM). And accessories such as clocks, audio systems (station presets), seats) remote door openers, and security systems also need power to maintain memory when the ignition is OFF. Each device with memory has a different amount load. The power used as a result of this continuous energy or cumulative load is called parasitic draw. It is usually a very small draw so the battery doesn’t become drained. Parasitic loads can run 20 to 120 milliamps. If there is an electrical short in the vehicle or a malfunctioning accessory it could draw more than its normal load causing a large drain on the battery and eventually a no start will occur.

General Specification Guidelines
0.00 – 0.022 Amps (0 – 22 mA) = OK BATTERY WILL LAST FOR ABOUT 2-3 WEEKS

0.023 Amps OR MORE (23 mA OR MORE) = NG* BATTERY WILL BE DEPLETED IN ABOUT 1 WEEK
