Note: If the battery temperature is too low (<0 °C, 32 °F) or too high (>40 °C,
104 °F) for charging, the LED will show green while flashing yellow. This will
continue until the correct operating temperature has been reached.
If the battery temperature exceeds 60 °C (140 °F), the LED will flash
between orange and green. The charger will stop charging and the battery
will have to be removed from the charging shoe and the charger will have to
be reset by disconnection from the mains.
Once the battery has reached full charge, the charger will go into top-up charge
mode and the LED will turn green and flash intermittently yellow. Once the top-up
has been completed, the charger will go into maintenance mode and the LED will
show green.
It is recommended that the battery be removed from the charging shoe once
charged. Before fitting another battery into the charger, allow at least 30 seconds so
the battery charger can reset; the LED turning to yellow indicates that the charger
has reset.
