Temperature Compensation
A sensor will automatically adjust the charging voltage if the temperature deviates between –
20°C to +50°C. At a high temperature environment the unit lowered the output voltage and at
a freezing condition, the unit will adjust a higher output voltage.
Voltage compensation
Because of some voltage drop in the cables, the actual voltage at the clamps of the battery
can be lower than the charger output voltage. A special circuitry inside the unit will monitor
the true input voltage to the battery and adjust the output voltage of the unit accordingly.
This will maximize the charging efficiency.
Reverse-polarity protection
This unit offers reverse-polarity protection, the RED "REVERSE" LED will illuminate, the buzzer
will warn the user and the charging process will not start. If this happens, unplug immediately
from mains, connect the red crocodile clip to positive (+) battery post, and black crocodile clip
to negative (-) post, then plug into the mains power and the charging process will start.
Short-circuit protection
Should you accidentally touch the crocodile clips together whilst the mains power is on, the
unit will not perform charging. Unplug from mains, disconnect and start the process again
being careful not to touch the clips together.
Temperature Control Fan
To protect the charger from overheating, a fan is included for heat dispensation. Also to
increase the life span of the fan, a sensor will control the on off of the fan, where the fan will
not use when the HFC is not in a hot condition.
Buzzer Warning
A built in buzzer will help to warn the user when connect the clamps to the battery wrongly.
Cable Management
The NFC Series casing is designed with AC and DC cables storage compartment. This will help
to avoid cable damage and subsequently any possible danger to user.

OPERATION

PLEASE READ CAREFULLY BEFORE USING
Suitable for 12V Normal Lead Acid, Sealed, Leisure, Gel or Deep-cycle Batteries
between 20-400Ah.
1. Charging your battery
It is essential to disconnect the battery from the car. This will avoid possible damage to the
alternator. To avoid damage to the bodywork from possible spillage, remove the battery
completely from the vehicle. It is advisable to use gloves when handling the battery, as there
is a high possibility of corrosive acid being on the outside of the battery.
.
2. Preparing the battery
Firstly remove the caps from each cell and check that the level of the liquid is sufficient in
each cell. If it is below the recommended level, top up with de-ionized or distilled water.
Note: Under no circumstances should tap water be used.
