NOTE
Currently, the encapsulated valve regulated lead acid (VRLA) batteries used in the
communication industry are all produced in full loading state, that is, the battery has been
charged with electricity fully.
Based on the battery features, automatic discharge will occur due to chemical reaction
during the delivery and storage process. In this case, the battery capacity and the open
circuit voltage decrease. We refer to this phenomenon as the automatic charge of the battery.
In a certain period, if you use appropriate methods, the voltage and the capacity of the
battery can be restored completely.
To make up the automatic discharge during the idle period, you need to perform the
supplementary charge for the battery in long idleness periodically. For this type of situation,
refer to "Operation Guide on Battery Supplementary Charge" to complete the
supplementary charge of the battery first, and then perform the following commissioning
procedures.
