User Manual
The VMAX BC1204A utilizes the latest technology in AGM, Gel and flooded lead- acid battery charging. Can be used with 7-80ah batteries. For best results, use with 7-60ah batteries. During the charging process; the charger’s 4 LEDs indicate the battery capacity status from 25% (LED 1) to 100% (LED 4). Fault LED: Light-Flashing,Battery is connected in reverse polarity or output is short-circuit Light-ON:The battery is worn out or is possibly defective. Suggest replacing battery with a battery
The BC1204A is a 7-Stage Charger
Stage-1: Qualification Phase Initially ensures the battery is in good
condition prior to launch of normal charge processes, as a safety measure
charge processes will not begin if battery is below 3 volts
Stage-2: Soft Start Phase: Soft Start is applied when the charger has detected
a battery at a very low initial state of charge Voltage and current are
delivered at a specified rate to help the battery to recover prior to entering
pulse charge mode
Stage-3:Recovery mode phase Recovery processes will commence if the charger
detects any charge acceptance problems，to help the deeply discharge battery
recover normal battery state
Stage-4:Bulk Charge Phase With the battery now having gone through
Qualification and Recovery phases as needed the Bulk Charge phase gives the
battery constant current, taking the battery up to 80% of its full Capacity
Stage-5:Adaptive charge Phase The Adaptive charge phase follows the charging
voltage changing when the battery voltage changes too quickly,the charger will
drop the charging current automatically.to ensure no overhot and no overcharge
the battery. Stage-6:Absorption Phase In the Absorption phase the battery is
given constant voltage while current is reduced based on actions taken from
ongoing battery monitoring until the battery is 100% charged
Stage-7:Maintenance phase The battery can be left safely connected to the
charger indefinitely. The charger will constantly monitor the battery and tum-
on again as needed to maintain the battery at a full state of readines

Instructions
- Connect the AC cord to AC outlet.The power LED will light on solid.
- Connect positive charger clip (red) to positive battery terminal,the black clip to negative.the 25%~100% LEDs will light in a sequence.If the batteries polarity is reversed or output is shorted,the ” “LEDs will flash simultaneously, DISCONNECT & CHECK.
- Depending on the charged capacity,25%~100% LEDs will light up solid.When all are ON,the battery is fully charged.You can disconnect thebattery to use OR keep it connected to charge in float mode.If battery stays at Stage 3 (25% LED ON )after 24 hours of charging,then the battery is defective.
The table shows the duration of the Bulk step-up to about 80%state of charge

WARNING
- This charger is designed for charging AGM, GEL & lead-acid, batteries from 7 to 8 0Ah. Do not use for any other purpose.
- Since batteries may emit explosive gases, always provide good ventilation and avoid any source of flames or sparks when charging.
- To reduce risk of damage to electric plug and cord, pull by the plug rather than by the cord when disconnecting charger.
- Use of an improper extension cord could result in a risk of fire and electric shock.
- Do not operate charger if you notice any signs of damage to charger or cords.
- Do not disassemble the charger; take it to a qualified serviceman when service or repair is required. Incorrect reassembly may result in a risk of electrical shock or fire.
- To reduce risk of electric shock, unplug charger from AC outlet before attempting any maintenance or cleaning.
