9. TOOTH LE Volume 4 No 4 Dealing In automotive terms a parasitic drain is an electrical load that draws current from the battery when the ignition is turned off Some devices such as the PCM and radio memory are intended to draw a very small amount continuously These draws are measured In milliamps mA In normal use parasitic drains aren t usually cause for concern because the battery is replenished each time the vehicle is driven But in long term parking situations parasitic drains may discharge the battery enough to cause a no start condition New vehicles in dealer stock and airport long term parking are two such situations An abnormal parasitic drain could be a glovebox or luggage compartment light that remains on but undetected Or an electronic component may malfunction and cause a parasitic drain that is larger than normal specification continued on page 3 Tech 2 EVAP Service Bay Test Re enabled For many years emission regulations have required an on board system to trap fuel vapor from entering the atmosphere Even a very small leak in the EVAP system could allow vapors to escape So on board leak detection is an important function of the EVAP system Government requirements sometimes change this has happened to EVAP regulations Currently the on board diagnostics must be able to detect a leak as small as 0 020 inch 0 51 mm The Tech 2 EVAP Service Bay Test is useful because it can tell t

13. e hours AH from full charge to complete run down Somewhere between full charge and complete rundown the battery will reach a point at which it can no longer start the engine although It may still operate some of the electrical accessories Using up about 40 of the total available AH will usually take a fully charged battery to a no start condition at moderate temperatures of 77 F 25 C Put another way for a typical battery in a storage Situation depleting the available AH by 20 to 30 AH will result in a no start condition TIP f the battery begins storage at 90 of full charge reduce the available AH accordingly The recommendation for maximum parasitic drain is around 30 mA 0 030 amps A typical drain today actually falls into the 7 12 mA range even though some vehicles do approach the maximum Multiply the drain in amps by the time in hours the battery sits without being recharged The result is the amount of AH consumed by the parasitic drain The actual drain may be small but over time the battery grows steadily weaker Here s an example A vehicle with a 30 mA drain and a fully charged 70 RC battery will last 23 days But if that battery is at only 65 of full charge green dot barely visible it is going to last only 15 days before causing a no start The Effects of Temperature on a Standing Battery The parasitic drain will be fairly constant over a range of temperatures The important temperatur
14. e is that of the vehicle at the time a start is attempted Colder temperature raises the threshold of a no start by increasing the residual power needed When the temperature falls to 32 F 0 C the battery will be able to put out only about 85 of its normally available starting power and the engine may need as much as 165 of the usual power to start The combined effect of these two factors is to reduce the number of days the battery can stand with a parasitic drain At 32 F 0 C the battery can stand only half as long as it could at 77 F 25 C And at O F 19 C the standing days are reduced to one fourth Temperatures above a moderate climate of 77 F 25 C increase the battery s internal self discharge If the battery is in a locale where the temperature Is averaging 90 F 32 C an additional 5 to 10 of the available ampere hours will be lost in a month due to self discharge within the battery At temperatures below the moderate range self discharge will be low enough to be negligible compared to the parasitic loss What the Policies and Procedures Manual Says About Parasitic Drains Because determining how long a battery may last in a storage situation is not precise the P amp P manual provides a clearcut policy excerpted here Discharged batteries can freeze at temperatures as high as 32 F 0 C causing permanent damage Other permanent damage may result from allowing batteries to stand disc
