POWER: Internal Battery Specifications 960mAh Lithium Polymer, 4.20 Volts fully charged External Power Requirements Bus Power 8-30 Volts DC, non-polarised, current draw is 190mA maximum at 17 volts per logger USB Power 5 Volts DC Internal Charge Rate Bus Power 60mA – 200mA Variable internal charge rate, maximum charge rate of 200mA active when the external voltage rises above 16 Volts DC USB Power 100mA fixed charge rate Internal Power Management Fully Charged Battery 4.20 Volts Low Power Mode 3.60 Volts – Instrument ceases to take measurements Discharged Battery 2.90 Volts – Instrument automatically switches off at and below this voltage when no external power connected. Battery Life varies Example A: With a recommended solar panel and/or recommended power source connected, operation can be continuous. Example B: Power consumption is dependent on number and type of sensors connected, frequency of measurement and measurement duration
