The internal resistance of the cell varies with state of charge, as follows:
Cell Charged
Cell 1/2 Discharged
100 milliohms
120 milliohms
(Tolerance of +- 20% applies to above values)
AC Impedance (No Load)
The impedance of the charged cell varies with frequency, as follows:

Ranges of temperature applicable to operation of the HR03 cells are:
Charge @ 0.1C: 32°F to 122°F (0°C to 50°C)
Discharge @ 0.1C: -4°F to 122°F (-20°C to 50°C)
Storage: -40°F to 122°F (-40°C to 50°C) (6 Months Max.)
-4°F to 95°F (-20°C to 35°C) (2 Years Max.)
Operating at extreme temperature will significantly effect service and cycle life.
