The invention relates to an applicable type
cell float charger and belongs to the electronic technology field. The applicable type
cell float charger comprises a
constant current charging unit, a discharging unit, an interface unit, a pulse unit, a selection unit, a counting unit, a
voltage limiting starting unit, a
load unit, a process indicator unit, an ending unit and a
trickle resistor, wherein the
constant current charging unit, the discharging unit, the pulse unit and the interface unit commonly form a charging / discharging pulse charging mode, the charging time is longer than the discharging time, a
triode of the
constant current charging unit is in a constant
current mode, so constant current charging is realized. The float charger is advantaged in that an ending mode after fully charging of a
cell and an ending mode after timed counting in place are employed and are two flexible conversion
modes, the needed
trickle current is provided by the
trickle resistor to the charged cellafter charging ending, a discharging
cut-off switch is arranged in the discharging unit, charging flexibility is realized, after
enforcement, scientific and maximum charging of the charging cell is realized, and service life and the capacity of the charger and the charged cell are improved to the maximum degree.
