k) Low current mode
An optional mode that limits the maximum charge current to a significantly reduced level;
recommended when charging lower capacity batteries with a high current charger.
l) Recovery function
The Blue Smart Charger range will attempt to recharge a severely discharged battery (even
down to 0V) with low current and then resume normal charging once the battery voltage has risen
sufficiently - many other chargers will not recognise a battery in this state.
m) Power supply mode
A specific mode to use the charger as a DC power supply; to power equipment at a constant
voltage with or without a battery connected.
