Page 14: Precautions For Battery Use
8.4 Precautions for battery use Because the passivation of the ER battery electrode surface is an inherent characteristic of lithium thionyl chloride batteries, before using the ER14505 3.6V 2400mAh lithium thionyl chloride battery, the user can use a 33 ohm resistor to activate the battery for 1 minute to actively eliminate the battery hysteresis.
