What Signs Indicate That It’s Time to Replace a TPMS Battery?

The signs that indicate it’s time to replace a Tire Pressure Monitoring System (TPMS) battery include several visual and functional cues.

Warning light on the dashboard.
Inaccurate tire pressure readings.
Frequent alerts or notifications.
Physical inspection shows battery corrosion.
System malfunctions or resets.

These indicators provide useful information on the operational state of TPMS. Understanding these signs can help maintain vehicle safety and performance.

1. Warning Light on the Dashboard:

When the TPMS warning light illuminates on the dashboard, it signifies a potential issue with tire pressure, including a low battery. According to the National Highway Traffic Safety Administration (NHTSA), this light generally appears when tire pressure is 25% below the recommended levels, but it can also indicate a failing TPMS battery. Drivers should pay close attention to this signal to prevent further complications.

2. Inaccurate Tire Pressure Readings:

Inaccurate tire pressure readings can indicate that the TPMS battery is losing power. The TPMS relies on battery-operated sensors to communicate tire pressure back to the vehicle. When the battery becomes weak, the sensors may provide erroneous readings, resulting in the driver receiving incorrect information. A study by the Automotive Research Association found that approximately 15% of vehicles with TPMS exhibit incorrect pressure formats due to failing batteries.

3. Frequent Alerts or Notifications:

Frequent alerts or notifications regarding low tire pressure can suggest that a battery is nearing the end of its life. These alerts may occur even when the tire pressures are correct. This malfunction points toward possible battery failure impacting the system’s reliability. Continuous alerts can be frustrating to drivers, leading to time-consuming checks and inspections.

4. Physical Inspection Shows Battery Corrosion:

A physical inspection may reveal signs of battery corrosion. Corrosion can occur at the terminal connections of the TPMS sensor batteries, indicating they are nearing failure. Drivers should check sensor mountings during tire rotations or replacements. If corrosion is visible, it often signals that the battery needs replacing to maintain optimal sensor performance.

5. System Malfunctions or Resets:

Frequent malfunctions or resets in the TPMS may also indicate battery issues. If the system regularly needs to be reset or fails to activate, it can be a sign of a dying battery. This can detrimentally affect the driver’s ability to monitor tire pressure accurately, leading to safety risks. It’s advisable to address these issues promptly to ensure the vehicle remains in good working condition.

By monitoring these signs and addressing any issues promptly, vehicle owners can ensure their TPMS serves its purpose effectively and maintains safety on the road.
