Normally, trackers design for theft detection and reporting can not be re-used for active tracking without changing firmware.
The first one is triggered by a dedicated signal from within the car to be activated. Otherwise they are offline to conserve energy. Energy is a very very limited resource in a car. When they are activated, they send a text message for the GPS position. Only a vary view newer once can trigger a web request to report the GPS position. When they are activated they can receive text messages to execute commands like disabling the engine.
Versus active trackers are the once mostly designed and engineered within the last 5 years, are able to consume very low energy while activated. They report the position (and may acceleration, deceleration and other parameters) via a web request.
Theft prevention are mostly established legacy systems more than 10 years old. Thats a different technology then we are used today.

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.
- PinguTS 11y agoYou 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.
