Boost Phase: starts up automatically when the charger is turned on if the battery is flat. The current is then at
maximum output.
Absorption Phase: begins when the voltage has reached the maximum Boost level. The current level starts
falling.
These two phases combined last a maximum of 4 hours. If the current falls below 15% of rated current, the
floating phase automatically kicks in. Duration and current intensity depend on how charged the battery is.
Floating Phase: starts after 4 hours or if output current has reached 15% of the charger's rated current. The
voltage switches to the Floating value and the rated current continues to drop.
