The ones used here are activated remotely. If we assume the tracker to be similar to a cellphone and that it goes into standby mode after the car is of it will be drawing in about 2 - 4 ma, considering that a small car battery has a capacity of 45Ah the consumption would be negligible, it would deplete the battery in 625 days.

You are not working in automotive? mA is a considerable amount even when running. In switched off mode, any ECU (with very few exceptions) should not draw more than 100 nA.

Remember, there is not only 1 ECU. There are around 40 to more than 100 ECUs. A battery should deplete not more than 50% in 8 weeks.
