Question Battery life expectation of tpms sensor?

Hi to everyone,

I am new here in the forum, but I've wanted to ask this question for some time now. What is your battery life expectancy if using modules such as TyreWiz, SKS Airspy or Fobobike (they all use 3V coin batteries) ?
All these devices can read out your tire pressure and transmit it via Bluetooth to your Garmin and/or the smartphone app.

Thanks for your answers

After reading the amazon reviews on the Fobobike, seems likes 5% of the buyers had them either fail or leak, draining their tires flat. I suppose that if you buy Energizer or Durocell, that the batteries will last longer than the device.Granted, these are on automobile wheels, which spin the devices 3-4X faster than a bicycle. Anyway, I use coin cells in a lot of things, micrometers, guitar tuners, and they last about a year if I remember to turn the displays off. . These have no display but bluetooth must always be listening.

While it looks like fun technology, sure doesn't look like reliable technology, and not necessary for me with regular bike tires. . I will continue giving my tires a squeeze before going out on a bike ride. The fat tires, I have to pull out my tire gauge.
