Two button cell batteries (CR2450HR) delivering 3V power, designed for TPMS tire pressure sensors. These replacement cells provide the correct form factor and voltage for sensors specifying the CR2450HR battery type, including compatibility with Maxell sensors where CR2450HR is required.

Key Benefits

Correct Fit and Voltage: CR2450HR 3V button cell batteries match the dimensions and electrical requirements for TPMS sensors that require this battery model, making replacements easy.

Restores Sensor Function: Replacing worn-out batteries helps regain accurate tire pressure reporting and avoids interruptions in sensor communication.

Easy to Install: Standard button cell battery size and polarity make replacements quick during routine tire service or when a low battery warning appears.

Compact, Purpose-Built: The button cell format fits inside small sensor housings without modification.

Product Details

Quantity: 2 pieces

Model: CR2450HR

Nominal Voltage: 3V

Form Factor: CR2450 button cell

Intended Use: TPMS tire pressure sensors specifying CR2450HR

Compatibility and Fit

Intended for TPMS sensors that require CR2450HR 3V batteries. Compatibility may include sensors from Maxell that use the CR2450HR designation. Confirm the battery model printed on your sensor or in the sensor documentation beforehand.

Typical Usage Scenarios

A discharged TPMS sensor battery after receiving a low battery warning on the vehicle's dashboard to restore correct tire pressure monitoring.

Replace batteries during seasonal tire changes or routine maintenance to ensure sensors remain reliable for a driving season.

Service a sensor after it has been removed for tire or replacement and the battery voltage is checked as low.

Installation Instructions

Observe correct polarity when installing the button cell battery. The sensor housing will indicate positive and negative orientation.

Handle batteries with clean, dry hands and avoid short-circuiting the terminals.

Follow the sensor manufacturer's guidelines for resealing and tightening torque when reinstalling the sensor in the wheel.

What to Expect

A direct replacement in sensors specifying CR2450HR, providing the specified 3V supply in the standard CR2450 form factor. Includes two replacement batteries suitable for battery changes in TPMS sensors.
