Battery Test and Precharge (Stage 1):
Check the battery voltage to make sure battery connections are good and the battery
is in a stable condition before beginning the charge process
Desulphation (Stage2):
Detects sulfated batteries. Pulsing current and voltage, removes sulfate from the
lead plates of the battery restoring the battery capacity
Soft Start (Stage 3):
Initial battery test to determine battery condition. If the battery is severely dischar-
ged, charger will begin the Soft Start stage. Charging starts with reduced current
until battery voltage reaches a normal condition for charge.
Bulk (Stage 4):
Major charging stage where the battery receives the majority of its charge.
During this stage the battery brought to 75 - 80% of its charge. The charger delivers
maximum current until the terminal voltage has risen to the full charge level for Nor-
mal battery.
Absorption (Stage 5):
Completes the charge up to virtually 100% at a constant voltage. The current tapers
off after the current reached the minimum level.
Recondition (Stage 6):
Select “Recondition” mode, charged by higher voltage to recondition the sulfate of
the battery to save battery life.
Analysis (Stage 7):
Tests if the battery can hold charge. Batteries that can not hold charge may need to
be replaced.
Float (Stage 8):
Low constant voltage, minimal charge current, battery is fully charged
Pulse (Stage 9):
Maintaining the battery at 95-100% capacity. The charger monitors the battery volta-
ge and gives a pulse when necessary to keep the battery fully charged
Power Supply:
MB3613 has a power supply mode setting which has a constant voltage of 13.8V
and current up to 5A, keep to provide power to computer system of modern car
when replacing battery (Please don’t reverse battery connection to avoid the
damage on the charger).
Temperature Compensation
A sensor will automatically adjust the charging voltage if the temperature deviates

from –20°C to +45°C. A high temperature environment will lower the voltage and fre-
ezing condition is handled by higher voltage. A low temperature heightens the output
voltage, and hot condition is handled by lower 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
Reverse-polarity protection
This unit offers reverse-polarity protection under charging modes, the RED LED will
illuminate and the charging process will not start. If this happens, unplug immediately
from mains, connect the red clamp to positive (+) battery post, and black clamp to
negative (-) post, then plug into the mains power and the charging process will start.
Short-circuit protection
Should you accidentally touch the clamps 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 clamps together.
Charge Memory
If power off on charging, MB3613 can automatically restart charging base on pre
-vious on previous power down status for battery and charging current.
ATTENTION: Once the clamp of charger is disconnected from the battery, this me-
mory is erased and the charging mode will need to be reselected.

START CHARGING YOUR BATTERY
PLEASE READ CAREFULLY BEFORE USING
Suitable for 12V and 24V Normal Lead Acid, Sealed, Lipo4, Leisure or Gel Bat-
teries between 5-150Ah for 12V batteries and 5-120Ah for 24V batteries.
1. PREPARING THE BATTERY
•Firstly remove the caps from each cell and check that the level of the liquid is
distilled water.
Note: Under no circumstances should tap water be used.
•The cell caps should not be replaced until charging is complete. This allows any
gases formed during charging to escape. It is inevitable that some minor escape of
acid will occur during charging.
For permanently sealed battery, it is not necessary to carry out the above checks.
2. CONNECTION
•Connect the positive charging lead (red) to the positive terminal post of the bat-
tery (marked P or +). Connect the negative charging lead (black) to the negative
terminal post of the battery (marked N or -).
Once you connected the MB3613 battery charger to AC power, it will sound
a tone for 0.5 seconds and all of the LEDs on the touch panel will be on for a
short time.
Warning! Always disconnect the AC plug from the AC mains socket before
connecting or disconnecting the appliance to or from the battery.

3. CHARGING
•Connected to power supply and the battery, the charger will automatically enter into
charging status, it is working on slow charging stage for 12V batteries by default. The
slow charge icon will illuminate, and the charger is automatically detecting the battery.
This is the standard charging mode.
•
different charging mode:
1. Hold the Mode key to switch to 24V and back.
2. Pressing the mode key to select one of the nine charge modes.
•After 5’’ the charge starts according tothe setting.
4. WHEN CHARGING IS COMPLETE
When the Stage 8 icon and Full illuminates, the battery is completely
charged. The battery charger now switches to the Float mode and doesn’t require
your attention until the next time it is used, it will automatically maintain your battery.
If LCD stage 9 icon illuminates, it indicates that the charger has automatically
maintained your battery.
Switch off the mains supply, unplug the charger, and disconnect the leads from the
battery posts. NOT to be done for permanently sealed battery: Inspect the liquid
extreme care as it may be acidic/corrosive).
Where appropriate, if the battery has been removed for charging, replace it and
reconnect the cables.
5. BATTERY FAULT
If fail red LED indicator lights or blinks and LCD Fail icons illuminate,
the following occurs:
Er1 - Fail Red LED blinks
Improper connection of Charger and battery polarity
Er2 - Wrong battery
Battery voltage 12V mode ≥15V, 24V mode ≥30V
Er3 - Battery voltage doesn’t reach a normal condition for charge.
12V (4V- 8V 2Min ) , (8V-10V 9Hr)
24V (4V-16V 2Min ) , (16V-20V 9Hr)
Er4 - Battery that can not hold charge
Er5 - Charging stopped under “Desulphation” or “ Absorption” mode, then press “MODE”
button could resume to charging, if still have the same problem, maybe caused by:
•1. Battery is over-sulfated
•2. Battery can’t be charged
•3. Battery can’t hold the charge
Under these conditions, the battery charger will stop charging.
Flashing red LED and a buzzer mean wrong battery voltage selection.

MAINTENANCE AND CARE
It is essential to keep your battery regularly charged throughout the year, especially
during the winter months. In the winter the effectiveness of your car battery is redu-
wipers and lights are all draining power. It is at this time that batteries have to be at
peak power. If your battery is not regularly maintained and kept fully charged, it can
cause problems and a possible breakdown.
Listed are some helpful hints on how to keep your battery healthy in conjunction with
your Battery Charger.
Faulty Cells
Batteries are usually made with six cells. One of these cells can deteriorate or get dama-
, you should test the battery.
ONLY for NOT sealed batteries:
Take hydrometer readings from each cell in the battery. If one reading is lower than
the others, this could indicate a faulty cell. If necessary, get an Auto-Electrician to
check your battery. One faulty cell is enough to ruin your battery.
It is pointless to continue using it and you would be better getting a new one.
Care
-
nections on your battery terminals. It is important to maintain the leads on a regular
basis. Do this by removing the leads from the battery, clean the inside of each con-
nector and terminal posts on the battery, smear the terminal posts and connectors
It is essential to keep the electrolyte level above the plates.
When topping up do not use tap water. Always use distilled or de-ionized water. It
is important to keep the acid level up. If necessary have it checked by your garage.
Checking the condition of your battery (ONLY for NOT sealed batteries)
