Internal Resistance:

The internal resistance of the cell varies with state of charge, as follows:

Cell Charged	Cell 1/2 Discharged
11 milliohms	21 milliohms

(tolerance of ±20% applies to above values)

AC Impedance (No Load):

The impedance of the charged cell varies

with frequency, as follows:

Frequency (Hz)	Impedance (milliohms)
	(Charged Cell)
1000	9

Above values based on AC current set at 1.0 ampere.

Value tolerances are ±20%.

Operating and Storage Temperatures:

To maintain maximum performance, observe the following general guidelines regarding environmental conditions.

Charge: 0ºC to 40ºC

Discharge: 0ºC to 50ºC

Storage: -20ºC to 30ºC

Humidity: 65±20%

Operating at extreme temperatures, will significantly impact battery cycle life.
