Car Forum / Chevrolet / Chevrolet Trucks / December 2006TrailBlazer discharge
I am having low battery problems. My battery discharge rate is about 7.5 milliamperes after the modules power down. The engine alternator running voltage is 14.2 volts and seems ok. What is the acceptable battery discharge rate at rest on a 2002 LTZ TrailBlazer? Thanks!! > I am having low battery problems.

That is fine, at that rate it would take about 6 to 9 months (give or take depending on interally battery leakage) to kill battery. It takes a little power keep ECM and clock current memory wise and then there is wireless remote receiver too. All thing considered 7.5 milamps (or about 1/100 or a watt) it pretty good. ----------------- TheSnoMan.com Actually more like 1/10 of a Watt (0.09 W at 12.0 V)....but still small. >> I am having low battery problems.

About 2.2 watt hours a day and a car battery depending on its size will store about 600 to a bit over 1000 watt hours when discharged at a very low rate so 2.2 watts a day is nothing unless you plan to let it sit more than 3 to 6 months at a time a lot without running or being recharged.. ----------------- TheSnoMan.com Good news!! Any posibility of the many heavy electronic systems on the LTZ coming on and doing an increased drain and I havent caught them? >>Actually more like 1/10 of a Watt (0.09 W at 12.0 V)....but still small > [quoted text clipped - 5 lines] > ----------------- > TheSnoMan.com >Good news!!

Are you having problem with battery dying? ----------------- TheSnoMan.com Probably so.. Local Chevy dealer says the battery is ok.. also took it by Advance and they said it was ok too... Both had newer testers, no actual resistive load was used...I still believe the 1 year old battery is sick!! I will look at a longer term test. thank you >>Good news!!
