Following the maximum time of 180 minutes, a pulse-trickle charge mode is used
to compensate for the self-discharge of the battery while idle in the charger.
The batteries are small, and the fast charge current is low. The fast charge
current is low enough that there is not always enough heating of the battery cells
to cause the voltage to drop. With no voltage drop there is no peak voltage
detection, and the fast charge will terminate after the maximum time of 180
minutes is reached.

The probe has internal circuitry to track the charge condition of the battery. NiMH
batteries have a sharp discharge-curve knee, which means there is little
indication that the battery is nearly discharged prior to a low battery condition.
The internal circuitry tracks the charging and discharging currents of the battery
and displays the calculated battery condition.
It is possible that the battery charge indication may lose synchronization with the
actual battery condition. A loss of synchronization may be indicated by a low
battery charge alert after the battery was recently fully charged. Loss of
synchronization may also be indicated by short battery life and premature low
battery alert.
To synchronize the battery charge indicator:
1. Make sure the power switch on the probe is set to the OFF position or
the battery will not charge.
2. Connect the battery charger to the electrical mains, and then connect
the charger output to the charger jack on the probe.
3. Press the DISCHARGE button on the battery charger. The battery will
fully discharge, and then fully recharge. The total time required to
discharge and recharge is approximately seven hours.
4. For best results, repeat the process once. However, it may be
necessary to repeat the process three times for proper
synchronization. The synchronization process may take up to
12 hours.
When completely charged, the battery indicator for the probe should indicate a
charge level of more than 90%.
