20 mA current loop data interface

Operates on six 1.2 Volt NiCad (standard) or alkaline batteries

Battery life: Approximately 1500 charge/discharge cycles

Battery duration between charges: Approximately 8 hours of continuous use before the scale shuts itself off. (These numbers are lowered by the use of the lamps or active current loop transmission.)

Charging voltage: 11.5 Volts - 14.5 Volts DC. Protection is provided for accidental reversal of the charging connections

Charging current starts at 300mA and drops down to 50mA after eight hours

Charging time: Eight hours if the batteries are discharged to the point of turning off the scale
