If the battery is passivated, then the degree to which it is passivated is examined in step 1003. If the battery is highly passivated, then it is depassivated by applying a load for long term (15 minutes—step 1005). If the battery is medium passivated, then it is depassivated by applying a load for a medium term (10 minutes—step 1007).

Passivation prevents the battery from internal short circuit and extends the battery shelf life. The passivation layer increases the internal resistance causing low voltage levels at a load startup quickly followed by a de-passivation; the cell voltage then recovers to its expected value under the given load.
Higher temperature causes a thicker passivation layer, thus storing at cooler (room) temperature helps mitigate passivation layer growth. Consequently, using fresher batteries helps assure a less resistive passivation layer has formed in the battery. The passivation layer is diminished by appropriate electrical current flow through the cell.
Passivation is a surface protecting reaction which occurs spontaneously in all lithium batteries which are based on a liquid cathode. Passivation prevents the battery from internal short circuit and extends the battery shelf life.
Passivation in a lithium thionyl chloride battery cell is a chemical reaction between the solid metallic lithium metal and the liquid catholyte (cathode and electrolyte) in the cell. It is a self-assembled, thin, highly resistant layer of lithium chloride crystals on the surface of the lithium metal.
Battery de-passivation is a process that “conditions” the battery for proper operation.
