TPMS? Battery life?

So, multiple questions:

I have a 2014 JKUR, it just turned 160,000 mostly fun miles today. I think new tires are in order, yet while examining some fault codes for a hopefully unrelated issue, I found B210A - system voltage low. I’m thinking this has something to do with the 5 sensor batteries in the wheels?

Does anyone know offhand if the batteries are replaceable? It seems that the inter webs think some are and some are not. I suspected this day would come, and I’m a bit nervous about dropping somewhere between $300 and $1200 on new sensors if they aren’t really needed.

So, general thoughts?
Is 9 years / 160k a good run for sensors?
Mine report the individual wheel pressures, and I want to preserve that. Does anyone know offhand if all have that function or is it a separate part number?

Anyway, just seeking broadly for additional knowledge.

Thanks!

Hi, the sensor batteries are not replaceable and, yes ~10 years is the upper end of their estimated life. Replacements will work the same - you do not have to get (expensive) OEM sensors. The B210 code is likely your main battery.
