It is not practical to monitor the mid-point voltage throughout the day. Therefore, a
more practical approach is to look at periodic log files stored inside the Battery
Monitor and examine the minimum values recorded for Va1 & Va2. If they differ
beyond 1.5 V, maintenance may be required. Another option is to compare these
minimum voltages to double (two times) the value of Vm. If these are close in
value, it can reasonably be inferred that the batteries are healthy.
Note: The above explanation is provided as a recommendation and not
expected to be an accurate method of determining the state of health for the type
of batteries you own. Consult with the battery manufacturer to determine how the
sensing of mid-point and logging over a period of time can be used for
determining information about battery health and maintenance needs.
Synchronization
In order to keep the Battery Monitor delivering accurate status information about
the battery, it is important to synchronize it regularly. Synchronisation is also
needed before the Battery Monitor can initially be used. During operation, the
Battery Monitor automatically indicates when a synchronisation is required by
displaying the message SYNCHRONIZE.
Performing synchronizations regularly is also important to increase battery life
and keep the battery healthy. If charge cycles are being performed regularly, the
Battery Monitor will most likely not display the SYNCHRONIZE message since the
battery is already being kept in sync with the Battery Monitor.
To manually synchronize the Battery Monitor:
In addition to automatic synchronizations for meeting the Auto-Sync Functions,
the Battery Monitor can be manually synchronized with the battery when the
battery is fully charged. This is done by pressing and holding both < and > keys
simultaneously for three seconds or until the flashing Full message appears on
the display, just like when it is automatically synchronized.
