HULK Professional 7.5A Battery Charger
is designed
for charging 12V/24V 10-240Ah Lead-Acid rechargeable
batteries and 10-80Ah Lithium batteries.
WARNING! DO NOT ATTEMPT TO CHARGE A
NON-RECHARGEABLE BATTERY
(PRIMARY CELLS)
• Before charging make sure the input power is as per
rated specifications, otherwise the charging
performance may be seriously affected.
•
Do not
use the charger with a damaged cable. It
must be replaced by the manufacturer, its service
agent or similarly qualified technician in order to
ensure safety.
• Never charge a damaged battery.
• Never charge a frozen battery.
• Never place charger above battery being charged,
gases from battery will corrode and damage charger.
•
Do not
cover the charger while charging.
• During charging the battery must be placed in a well
ventilated area.
• While charging always use safety glasses, gloves,
protective clothing and keep your face away from the
battery.
•
Explosion hazard!
A battery being charged could
emit explosive gasses. Avoid smoking or open sparks
or flames in the vicinity of the battery. Explosive and
flammable substances such as fuel or solvents should
not be kept in the vicinity of the charger or the battery.
•
Danger of chemical burns!
Battery acid is highly
corrosive.
If your skin or eyes come into contact with acid,
immediately rinse the affected part of the body with
excessive water and seek medical advice.
• All batteries eventually fail. If that happens during charging,
charger’s advance control system will detect it, but there
may some rare errors still exist in the battery, so do not
leave charging unattended for a long period of time.
• Normally, a battery is grounded either, on negative or
positive terminal to the vehicle’s chassis. The
charger’s DC Clips are to be connected to the
battery terminal
not connected to the chassis first
.
The other connection is to be made to the terminal
connected to the chassis
, far from the battery and
fuel line. The battery charger is then to be connected
to the power supply.
• After charging, disconnect the battery charger from
supply mains.
Remove the chassis connection and
the battery connection
, respectively. This will
reduce back drain current.
• Keep away from children

Operation
Charging
1)
Charging of a permanently installed battery in a vehicle
a)
Before connecting or disconnecting the battery leads,
the power cord should be removed from the mains.
b)
Check polarity of the battery post. A positive (“+”) battery
post usually has a larger diameter than a negative (“-”) post.
c)
Identify the pole of battery which is connected to the
chassis (earth). Normally the negative terminal is
connected to the chassis.
d)
Charging of negatively earthed battery:
• Connect the red (+) clamp to the positive (+) terminal of
the battery.
• Connect the black negative (-) clamp to the vehicles
chassis away from the fuel line or any moving parts.
e)
Charging of positively earthed battery:
• Connect the black negative (-) clamp to the negative (-)
terminal of the battery.
• Connect the red positive (+) clamp to the vehicles
chassis away from the fuel line or any moving parts.
2)
Charging of a battery not connected to a vehicle
a)
Before connecting or disconnecting the battery leads,
the power cord should be removed from the mains.
b)
Connect the red clamp or eyelet terminal (“+”) to
the positive (“+”) pole of the battery and the black
clamp or eyelet terminal (“-“) to the negative (“-“) pole.
3)
Connect charger to the mains.
4)
Select charging mode
Charger automatically detects 12V or 24V batteries.
For 24V batteries
By pressing

charge options can be selected.
For 12V batteries
By pressing
MODE
button once, Standard or Cold
charge or

Charging Phases
HULK Professional 7.5A Battery Charger
performs 8-step fully automatic charging cycle.
Full
1) Diagnosis :
The unique diagnostic function checks
status of battery and ascertains if battery can accept
charging.
4) Boost :
Recovers severely discharged batteries under
high voltage charge. Recommended to apply it at least
once a year.
6) Absorption :
With use of declining current charging up
to almost 100% is achieved.
7) Analysis :
Checks status of charge. If battery does not
retain energy, it must be replaced.
8) Float :
Battery is fully charged and ready to use. The
battery is maintained at maximum level by applying low
current charge.
2) Recovery and 3) Sofstart :
A deeply discharged battery
of over 2.0V can be recovered and charged with pulse
charging of small current.
5) Bulk :
80% of energy is returned in this phase with
maximum charging current.
