Battery Fighter BFP-012 - Charging Stages and Operation; Qualification Stage; Bulk Charge Stage; Absorption Charge Stage

Stage 1) Qualification: Ensure the battery is in good condition and safely able to be charged.
The following symptoms are incurred if the Red light continuously flashes:-
• The battery voltage is detected too low, that is the battery voltage is lower than 4.0V (BFP-024), 2.0V (BFP-012),
the charging will not be commenced.
• The battery is not being connected properly, please check the connection of battery is clean & good.
• Reverse polarity connected.
Stage 2) Bulk Charge: Red Light On, Green Light Off, Constant Current = 5.0 Amps, Transition to Stage
3, Absorption Charge when battery voltage reaches 14.4 VDC.
Stage 3) Absorption Charge: Red Light On, Absorption Voltage = 14.4 VDC Transition to Float Charge
(Stage 4) when battery charging current drops below 2.5 amps.
Stage 4) Float Charge: Red Light Off, Green Light On. Float Voltage = 13.2 VDC. If an external load is
applied to the battery while the charger is in stage 3, Float Charge, and if the battery voltage drops below
a
range between 11.5 to 12.0 VDC, then the charge cycle restarts.
