THE CHARGING PROCESS
The HFBC12 has a sophisticated computer system that performs a 7 stage
automatic charging cycle.
The stages of this charging cycle are as follows:
STAGE 1 DIAGNOSIS (UPON CONNECTION TO THE BATTERY)
• Polarity check: to make sure that the connections are correct.
• Battery check: to make sure that the battery can accept a charge and
is not faulty, if it is the charger will not attempt to charge the battery.
Warning LEDs will come on if either test fails.
STAGE 2 PRE-CHARGE
STAGE 3 SOFT START
STAGE 4 CONSTANT CURRENT
Charges a discharged battery at a constant current depending on charge
mode selection.
Charges until the battery is 80-90% re-charged.
STAGE 5 CV(CONSTANT VOLTAGE)
This is a charging cycle for batteries nearly full. It will top off the battery to a full
charge.
STAGE 6 RESTING
Cuts off automatically when a full charge is reached.
STAGE 7 RESTORING
Automatic On-off Monitoring. The charger will maintain and optimise the
battery indefinitely so long as it remains connected to the battery. If the
battery falls below 12.8V DC, the charger will restart at stage one.

PREPARATION
1. If it is necessary to remove the battery from a vehicle to charge it, always
remove the grounded terminal from the battery first. Make sure that all
accessories in the vehicle are off to prevent sparking.
2. During charging, make sure that the area around the battery has good
airflow.
3. Clean the battery terminals. Be careful to keep corrosion from coming in
contact with eyes.
4. Add distilled water to each cell until the battery acid reaches the level
specified by the battery manufacturer. This helps remove unwanted gas
from the cell. Do not overfill. For a battery without cell caps, follow the
manufacturer's instructions.
5. Study all the battery manufacturer's specified precautions: for example,
removing or not removing cell caps while being charged, and
recommended rates of charge.
