Trailer TPMS battery life/replacement

[Cruisin'n5thgear]

Picked up a Yukon XL and added these tire pressure sensors to my utility trailer: https://accessories.gmc.com/product...10397?vin=3GTU9BED2LG141604&categoryId=106001

A couple questions for those who might know: Is it possible to replace the batteries in the sensors? Also, if I have some extra ones sitting in the console, will their batteries last longer than the installed sensors? I bought an extra 4 sensors in addition to the initial 2 in order to have extras. If the batteries are non replaceable and constantly running down, perhaps I should sell them now.

At $150/2 I'd hope the batteries are replaceable ... ...

Thanks for the input!

The batteries are not serviceable. Average life span is 8 to 12 years.

Think they last longer if they aren't installed in the wheel?
