Knowing the battery current drain limits will be important to confirm whether you have a parasitic draw or not (aka quiescent current draw). Most vehicles all around the same value of current drain, usually measured in milliamps. We also look at what value you are expecting on the multimeter amp setting as this can sometimes be confusing. If you get the right information from the customer, regarding how long the vehicle takes to drain, you will get a good idea of how big the parasitic draw is and give you better expectation of the battery current drain value.
