Deep discharge of the PAS614L energy storage leads to degradation of performance.
Therefore products have to be taken into operation after 36 months. At least the PAS614L
needs to be recharged to 2.1 V.
The module shall not be placed on conductive materials, to prevent discharge of
the internal energy storages

. Even materials such as conductive foam (ESD pro-
tection) may have negative impact.
