INTRODUCTION
The Mroinge MBC050L is a member of the family of advanced battery chargers manufactured
by Mroinge International Ltd. Mroinge chargers will increase your battery’s performance and
prolong its life.
We have taken numerous measures in quality control to ensure that your product arrives in
top condition and will perform to your satisfaction.
Please carefully read and follow the safety and operating instructions. Not following
these instructions may result in a serious accident, including damaged property or
serious injuries.
IMPORTANT SAFETY INSTRUCTIONS
If you are not confident working with 12V DC voltage or are unsure of what you are doing,
consider to seek for professional help e.g. a car garage or your vehicle´s manufacturer.
Read your vehicle's owner's manual!
Some vehicle manufacturers may have special requirements before charging the vehicle´s
battery. (e.g. fuses that have to be removed or certain security demands).
You MUST NOT connect to 24V or other unsuitable batteries (e.g. NiCd-
batteries). The battery charger is not designed as a power supply. Not
following these instructions could cause serious personal injury or
material damage.
This unit has safeguards against reverse-polarity and short-circuit.
Although it is highly recommended not to touch or connect the red to the
black clamps or to connect the leads in reverse polarity. This could cause
dangerous sparks and electric arcing. Only connect and disconnect the
battery leads when the mains supply is disconnected.
Use the charger in dry environment only. Do not use the unit close to open fire. Do
not operate the unit in explosive atmospheres, such as in the presence of flammable
liquids, gases or dust. Please stop using the device, if the unit is getting very hot, is
smoking or is showing any abnormal behaviour. Mroinge is not liable for any direct
or indirect damages or injuries caused by the use of the device, especially caused by
failure to follow these instructions.
TYPE OF BATTERIES
This charger is intended to be used 6V/12V Normal Lead Acid, VRLA, Sealed (MF Maintenance-
Free), Leisure, AGM, GEL-Batteries and 12V Lithium(LiFePO4) between 7-160Ah.
Do not
try to
charge unsupported types of batteries like NiCd.
（
ATTENTION: This unit is only suitable for one type of lithium battery, It is 12V
Lithium(LiFePO4) only, Other types of lithium battery does not support.
）
GASES
When the battery is being charged, you may notice bubbling in the fluid caused by the release
of gas. As the gas is flammable, avoid naked flames, glowing or electrostatically charged
material and sparks in the vincity of the battery. Provide adequate ventilation. Because of this
risk of explosive gas, only connect and disconnect the battery leads when the mains supply is
disconnected.

STORAGE
When not in use, store the battery charger in a dry environment.
MAINTENANCE
Don’t try to open the body casing. There are no user-serviceable parts inside. Damage due to
improper use, modifications or attempted repairs lead to the exclusion of liability and the loss
of warranty. The mains supply cord of this device cannot be replaced; if the cord is damaged,
the appliance should be discarded.
PRECAUTIONS WHEN WORKING WITH BATTERIES
Avoid getting electrolyte on your skin or clothes. It is acidic and can cause burns. If
battery acid contacts skin or clothing, wash immediately with soap and water. Baking soda
neutralizes lead acid battery electrolyte. If electrolyte gets into your eyes, immediately flood
your eyes with running cold water for at least 20 minutes and get medical attention
immediately. Eye protection is therefore recommended.
Never charge a frozen battery. If battery fluid (electrolyte) becomes frozen, bring the
battery to a warm area to allow the battery to thaw before you begin charging.
Do not touch the battery clamps together when the charger is on.
Never use the charger when it has received a hard blow, been dropped, or otherwise been
damaged. Take it to a qualified professional for inspection and repair.
Prevent the power cord from being stepped on, tripped over, or being damaged.
Never pull out the plug by the cord when unplugging the charger. Pulling on the cord may
cause damage to the cord or the plug.
Although it is usually possible without causing problems to charge the battery when
installed, we recommend to remove the battery from the car before charging. When
charging the battery while installed in the car, Mroinge cannot take any responsibility for
harm to your car electronic or the car itself.
Never smoke or allow a spark or flame in vicinity of battery or engine.
Always keep metal objects or other materials that can short circuit battery terminals
securely away from the batteries. The resulting spark or short-circuit may cause an
explosion and can produce a current high enough to weld a ring or the like to metal.
Remove personal metal items such as rings, bracelets, necklaces, and watches when
working with starter batteries.

-Stage Charging Curve
The MBC050L is controlled by a 10-bit ADC microprocessor with 7-stage charging
characteristic for charging batteries automobiles, motorcycles, snow mobiles, tractors,
personal watercraft, boats etc.
A microprocessor senses the condition of the battery and controls the regulator to provide
the right current and voltage to the battery (charging characteristic). This will give the best
effect on charging and give the longest life to battery.
Charging characteristic:
•
[1] BATTERY TEST:
After connecting to the power supply, press Mode button to
select appropriate battery charging mode. After connecting to battery, the charger
will automatically detect the battery performance. In normal status, the battery will
enter stage 2 in 4 seconds. 12V lead-acid batteries lower than 3.5V or 12V lithium
batteries lower than 4V are invalid and beyond handling.
•
[2] DESULPHATION:
Detects sulfated batteries. Pulsing current and voltage,
removes sulfate from the lead plates of the battery restoring the battery capacity.
•
[3] SOFT START:
Initial battery test to determine battery condition. If the battery is
severely discharged, the charger will begin the Soft Start stage. Charging starts with
reduced current until the battery voltage reaches a normal charge.
•
[4] BULK:
Major charging stage where the battery receives the majority of its
charge. During this stage the battery is brought up to 75-80% of its charge. The
battery charger delivers maximum current until the terminal voltage has risen to full
charge level for normal battery.
•
[5] ABSORPTION:
Completes the charge up to virtually 100% at a constant
voltage. The current tapers off when the current reaches the minimum level.
•
[6] ANALYSIS:
Tests if the battery can hold charge. Batteries that can not hold
charge may need to be replaced(Fault LED is solid red).
•
[7] FLOAT:
Low constant voltage, minimal charge current, battery is fully charged,
and maintenance your battery.
