Contrary to common belief, GPS car trackers are unlikely to be the culprit behind a flat car battery. Experts explain that most modern trackers have their own dedicated power sources, and even those connected to the vehicle's battery use a negligible amount of electricity that couldn't single-handedly drain the battery. The real battery-draining culprits are more likely to be things like leaving headlights on, running the air conditioning, or letting the car sit unused for extended periods.

Why it matters

Correctly identifying the source of a flat battery can save car owners time, money and frustration. Blaming the car tracker, when it's not the true cause, could lead to unnecessary repairs or replacements. Understanding what does and doesn't impact battery life helps drivers better maintain their vehicles and avoid unexpected breakdowns.

The details

While car trackers are often an easy scapegoat, experts say the devices themselves rarely drain a vehicle's battery. Most modern trackers come with their own separate batteries, so they don't directly connect to or draw power from the car's main battery. Even trackers that do wire into the vehicle's electrical system use a negligible amount of electricity, far less than other common car features like the radio, headlights or air conditioning.

  • Car trackers have become increasingly common in vehicles over the past decade.

The takeaway

While it's easy to blame a car tracker for battery issues, the real culprits are more likely to be other vehicle features and habits, like leaving lights on or letting the car sit unused for too long. Understanding what does and doesn't impact battery life can help drivers better maintain their vehicles and avoid unexpected breakdowns.
