Cellular IOT on coincell


#1

Hi,

We are in the process of developing IoT bottles and want to find out if we can have cellular hardware run on coin cell batteries for a reasonable time?

Thanks

Hi, wish we could give some good news but it’s probably not possible. A single coin cell provides less than 1mA and even the lower power Cat-M modules are going to need over 70mA to get a connection under good conditions.
Might be able to run off of a few good AAs for a few hours if you’re smart about power but coin cells aren’t going to get close.

You got me thinking about this more and I found this thread: https://electronics.stackexchange.com/questions/234901/lithium-coin-cell-cr2032-battery-specifications
Sounds like you might be able to get enough power to do it with some capacitors but the battery would die in under an hour.

Thanks so much Reuben ! It is high time to have coincell cellular , I will follow up …three cheers !
