Battery life calculator

Chose sensor (ERS,ELT-1, ESM5k) and data coding(SF7-SF12).  Fill in number of samples per hour. Use “All sensors” field to change all time settings at once.

*Receive window2 (SF9) depends on server settings .

** Battery life is a theoretical value. Battery life is negatively affected by moister, high temperature, dirt, vibration and more. Most battery manufacturer grantees maximum 10 years of battery life (storage and usage).
