Question:
Been looking at the TPMS and concerned that the specs state Battery life: 2 to 4 weeks but some answers to question show 9-14 months. Can you clarify what is correct? I would hate to change batteries every 2 weeks as I will be traveling all winter.

Hey Gregg! I'm not sure where that 2 to 4 weeks came from but I wouldn't want to change out the battery that often either. The sensors that come with the TireMinder A1AS TPMS # TM79FR do have a battery life of 9 to 14 months, we have confirmed this with TireMinder. The monitor will last for 2 days on a full charge. I'll see if I can get that corrected on the page. The flow through sensors that come with the # TM86FR you ordered also have a 9 to 14 month battery life.
Where are you traveling this winter?
