Safety Rules and General Warnings
•Persons, who are not able to use the charger in a safe way, because of their physical, sensory or mental incompetence, or because of their
lack of experience, should not use without the control or instruction from a skilled or qualified person.
•The charger runs with 100-240 Volts alternating current, which is not suitable for children – Danger of Life. And beware of risk of electric shock
at all times.
•Ensure sufficient air ventilation; do not cover the vent outlet while charging in progress.
•Avoid flammable gases, solvents or vapours all the time. Prevent open flame or sparks while charging in progress. Explosion RISK!
•The charger is exclusively designed for charging specific lead-based or LiFePO4 rechargeable batteries. It must not be used for other purposes.
•NEVER recharge a frozen starter battery.
•WARNING: Battery acid is corrosive and may cause property damage and personal injury. In the event of direct contact with skin or eyes,
immediately rinse with plenty of clean water and contact a doctor.
•Please always wear appropriate work clothes, protective gloves and safety glasses when working with lead-based batteries.
•You should take into consideration of the charging instructions issued by the battery manufacturer before charging. Check also if the charge
profile fits your battery and application.
•DO NOT OPEN or DISMANTLE the charger. Repair work must only be processed by authorized technical staff.
•If the mains connection or the pole terminal adapter of the charger is damaged, it must be replaced with an original wire which is available at
MEC or authorized dealers.
•NEVER place the charger on top of the battery while charging in progress.
•The charger should be protected against direct solar radiation or temperatures over 40°C.
•In case of obvious damage or malfunctioning, disconnect the charger from the mains supply and protect against unintended reconnection.
•The DC cable must not be cut, shortened or extended under any circumstances.
•Keep the charger in dry room (rel. humidity <80%). Clean with dry cloth only. Avoid fluid of any kind to get into the charger.

Preparation –Before Charging
General Checking
•Check thoroughly the charger itself including all the cables show no damages
•Take into consideration the charging instruction issued by the battery and the application manufacturer to confirm the polarity, ground
connection or maintenance etc.
Charging Cable – Polarity Checking
WARNING: Check the polarity before mounting onto a plug:
•Red cable = Plus (+)
•Black cable = Minus (-)
DC Mains Supply Checking
•Make sure the DC cable must not be cut, shortened or extended under any circumstances
•Make sure the mains supply (of max.16A is allowed) complies with the technical specification requirements of the charger
Before Connecting the Charger to the Battery
•Make sure the charger is switched off and disconnected from the mains supply
•Then connect the terminals of the charger to the battery; if the charging socket polarity does not match the charging plug polarity on the
charger; make use of the pole terminal adapter (Red cable to the positive (+) terminal of the battery; then Black cable to the negative (-)
terminal)
•If the battery is built-in within a vehicle, the Black cable can be connected to the negative (-) terminal of the battery or the body of the vehicle;
make sure the connection is done with a safe distance from the fuel line and take into consideration of the battery and vehicle manufacturer
•Finally connect the power cable of the charger to the mains supply, and switch on the charger
Charging the Battery
Select the most appropriate charging program (WET, GEL, AGM, or LiFePO4). Universal Mode can charge all conventional lead-based or LiFePO4
starter batteries, and thus useful when the battery type cannot be clearly identified. The charging process starts automatically and runs through the
following stages:
Phase 1: Soft Start
Yellow Charge LED keeps on lighting. The charger regulates the initial charging current to better prolong the battery life.
Phase 2: Constant Current Charging
Yellow Charge LED blinks slowly. The battery is being charged to 80% of its capacity at this stage.
Phase 3: Constant Voltage Charging
Yellow Charge LED blinks quickly. The battery is being charged to its maximum capacity. When the Green Full LED turns on, the charger can now be
disconnected from the battery.
Phase 4: Float Charging (for lead-based batteries only) or Auto Restart
Green Full LED keeps on lighting indicate the battery has reached its full capacity. If the battery keeps connecting to the charger, auto restart of the
charging cycle will take place after 7 days.
Disconnect the Charger from the Battery:
1. First, disconnect the charger from the mains supply
2. Then, disconnect the charger from the battery
After disconnecting the charger from the mains, please wait at least 5 seconds to reactivate the charger if in need – otherwise damages may be
resulted.
Charging Advice and Battery Care
Charging Advice:
•If the charger must be disconnected from the battery during the charging process, please FIRST disconnect the charger from the mains supply.
The continuation of the charging process is equal to a new charging cycle; all relevant points of the Operating Instructions have to be considered.
•To lengthen the lifetime of the battery, please do not stop the charging process before the battery is fully charged. The charger will automatically
stop when the charging process is completed.
Battery Care:
•Never expose the battery to high temperatures, as this causes permanent battery capacity loss.
•Never deep-discharge or overcharge the battery, cells can be damaged irreversibly.
•If possible, always disconnect the battery from the load when being stored over long period of time.
•Store battery in a dry and cool place at about 40-60% of its rated capacity.
