The Remora tracking unit uses 4 x “C” cell batteries. The circuitry is designed to handle battery cell voltages from 1.5V to 3.6V. This allows the Remora to operate off a range of primary cells including low cost Alkaline batteries and top of the range Lithium-Thionyl-Chloride batteries for longer battery life and operations in extreme temperatures.

Predicting the battery life is quite difficult, due to the wide range of operating conditions.

  • The battery life is affected by: 
  • The type and quality of batteries used 
  • The type of modem (2G, 3G, LTE), and the average signal strength 
  • The average GPS signal strength available when installed 
  • The average temperature of operation 
  • The operating mode (periodic, GPS based tracking, accelerometer based tracking) 
  • The particular configuration of that mode 
  • The level of asset activity (trip quantity and length, loading / unloading jostling) 

To help inform the battery life prediction and evaluation process, many discharge tests have been performed, and approximate battery cost constants extracted.
