Q: How much draw can do accesory mode?

asked by on

I want to know how much draw can make a stock 2013 Chevrolet Trax LTZ (That includes Mylink 7" Screen, Sunroof...) on accessory mode, listening music from bluetooth at 10% volume? I know every car draws differents current, but to make an approximate, to say a number, how much it could be?

I ask because I was using the car to listen to music, 1 hour the 1st day and the next day 2 hours without turning the engine on, sometimes I turned the key into ON, just to check "oil lifespan", mileage and stuff I don't check while driving, since this car have automatic lights, I had to constantly turn them off, I also open and close the windows and the sunroof (When I get out of the car or someone talks to me), when I was close to get out of the car and go inside my house, I noticed the trunk light was on (God knows how much time was that lamp on, also my trunk have some trouble to be closed), minutes later the battery light comes in, I tried to turn the engine on, nothing, I got to jump start it.

The total amount of amps (or watts) drawn by the accessories that you are referring to can be determining by inserting an ammeter in the circuit (at the battery). As far as your question, even if the current drawn were relatively low, if the battery is already discharged, or if the battery is not in good condition, even a small current draw will quickly lower the voltage below the threshold required by the starter motor. What you should do if you believe that your battery is prematurely discharging after running just a few accessories, is have the battery load tested. If you request a no start diagnostic, the responding certified mechanic will both load test the battery, replace it if warranted and, of course, test your charging system to be sure that your battery (whether new or existing) is being properly recharged. If you have further questions or concerns, do not hesitate to re-contact YourMechanic as we are always here to help you.
