SmartTrunk Systems ST-1000C User Manual - End Of Charge:

End of charge:
As soon as the re-charge process has been completed the charger led
becomes green.
You can decide when the performance becomes too poor to buy a new
battery, but anyway, the battery life indicator will let you get an
approximate idea of battery health after the charging process ends.
Charging Failure:
ST-BC-02 gets information from the battery pack continously when
connected to the battery. All parameters are controlled; the charging
voltage, temperature and current are continuosly controlled on real
time.
If any of the parameters becomes out of normal status, the battery
charger will abort the process, then chargers LED will blink on red as an
idication of charging failure.
In case of failure, please remove the battery from the charger then wait
few minutes before trying again. Sometime, the charging temperature
is too high, or in case the radio is powered on, perhaps it demands too
high current enlarging too much the target time to end the charging
process.
Battery failure indication will also appears if the battery elements are
damaged or too aged.
Depending on the DC input voltage and the temperature, a complete
process will demand between 3 and 4 hours. If the radio is on during
the charging process, the time will extend, depending on the radio
activity.
