Battery Fighter BFP-012 User manual

BFP-012 12V 5A charger and BFP-024 24V 3A lead battery charger
The BFP is a Microprocessor controlled fully automatic 4 stage charger that charges more efficiently plus
extending battery life compared to other similar output chargers. Featuring a lightweight mountable chassis the
BFP series is also vibration resistant, dust proof & water resistant to IP65. Other features include spark proof
connection, reverse polarity protection on the PCB & an auto reset program. Available in two models, suitable for
12 volt batteries with a 5 amp output & suitable for 24 volt batteries with a 3 amp output.
GENERAL DESCRIPTION: The lightweight, mountable battery charger is a high frequency switching power converter
that has a true DC output at a maximum power level of approximately 70 watts.
SUITABILITY: Lead Acid Battery types - Standard; Flooded, Sealed, VRLA, GRT, AGM and GEL.
OUTPUT CABLE CONNECTIONS: The battery charger is equipped with an Constar type interchangeable
non-reversible connection output. Included in the package are a BFL2 leads fitted with permanent connect ring terminals:-
positive 3/8" diameter ring terminal with a red molded polymer insulation cylinder, negative 5/16" diameter ring terminal with
a black molded polymer insulation cylinder. BFL1 Alligator clips are the second connection type also included.

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.
