The Charger Voltage will be the voltage at the battery terminals.
The Charge Type gives the current charging method. The methods used are:-
BOOST – Constant current charge of 920mA. Used when batteries are flat
FLOAT
– Float charge is applied as the batteries approach a full charge
PULSE
– used when the voltage at the charger terminals is less than the final voltage. Used to check if the
batteries are present.
OFF
– Charger is turned off when no mains is present
