BLE TPMS Battery Change: CR1632, 1.5 Years, No Re-Pairing A BLE tyre sensor lives on a coin cell, and changing it should not mean re-pairing every wheel. What 1.5 years actually depends on, and how a battery change works.

The number, stated properly

Our BLE sensor runs on a replaceable CR1632 cell with an average life of about 1.5 years. "Average" is doing real work in that sentence: it depends on how often the sensor measures and transmits, on temperature, and on how far the phone is when someone reads it.

Three things shorten it: very cold ambient temperature, frequent long-range reads, and a measurement interval configured for a live dashboard rather than a daily check.

Why pairing matters more than the cell

The frustrating part of a battery change is not the coin cell — it is re-pairing. If a battery change wipes the wheel identity, a twenty-wheel machine becomes a twenty-position job, and nobody does that on schedule.

Our sensor keeps the pairing: change the cell and the identity stays. Full reading, wheel record and any history attached to it remain valid. That single property is what makes a battery change a two-minute job instead of a maintenance ticket.

How a change actually runs

• Open the sensor housing, swap the CR1632, close it.
• Read the wheel on the phone to confirm it answers and shows a plausible pressure.
• Check the seating and the cap; a cap that is not fully seated is the most common cause of

water ingress afterwards.

• Note the date in the maintenance record, so the next change is planned rather than reacting.

Two practical rules: use a branded cell (cheap cells are the usual cause of "the sensor died early"), and keep the sensor's IP67 seal intact — wipe the thread area clean before closing.

What we do not claim

We do not promise an exact month count, and we do not describe a phone-read sensor as a continuous monitoring system. If the application needs continuous data, the receiver-based family is the correct product; battery life there is a system question, not a coin cell question.
