3. Safety information

During the charging of batteries, explosive hydrogen is released; therefore, smoking near the charging battery is strictly prohibited!

• Place the charger only in specially equipped areas that exclude contact with explosive gases.

(!) • NEVER use the charger in enclosed or restricted spaces without proper ventilation!

• Charge only functional batteries. NEVER attempt to charge frozen batteries.

• Do not use the charger if the cable or plug is damaged.

• In case of electrolyte leakage from the battery, ventilate the room, disconnect the device from the mains, and only then disconnect it from the battery.

• Do not disconnect the charging clamps from the battery during the charging process. Wait until charging is complete or first disconnect the charger from the mains, and then remove the clamps from the battery.

• Keep the charger out of reach of children. Children must not use the device without adult supervision.

• When working with lead-acid batteries, always protect your eyes and clothing.

• If electrolyte comes into contact with skin or eyes, immediately rinse the affected area with plenty of soapy water and seek medical attention.
(!) Contact with acid in the eyes may result in loss of vision.

• Do not allow metallic objects to come into contact with the battery. This may cause a short circuit, fire, and consequently an explosion.

(!) • NEVER touch both battery terminals simultaneously during charging.

(!) ATTENTION!
The device is not intended for use by persons (including children) with limited physical, sensory, or mental capabilities, or lack of experience and knowledge, without appropriate supervision or instruction by a person responsible for their safety. Children should be supervised to prevent them from playing with the device.

4. Device structure

The charger is housed in a metal casing with ventilation openings.

On the front panel, there is an ammeter with a scale division of 0.5 A; LEDs "POWER", "ERROR", "BATTERY CHARGING", "BATTERY FULL"; a charging current adjustment knob, a power switch, and a battery voltage selector switch.

On the rear panel, there is a power switch as well as power cables for connection to the battery and the 220 V mains.

The electronic circuit is a unique single-ended high-frequency converter with a current limiting circuit. This design ensures high efficiency across a wide range of supply voltages, provides galvanic isolation, and offers excellent mass-to-dimension and power characteristics.

5. Functionality check

Make sure that the housing has no visible mechanical damage, the wire insulation is intact, and the ammeter needle oscillates around the “0” mark when the device is lightly shaken.

To check the functionality of the charger without connecting it to a battery:

1. Ensure that the output clamps are not shorted together.
2. Connect the device to the 220 V mains.
3. Switch the power switch to the "ON" position. A malfunction is indicated if the green LED lights up and the built-in fan starts running.

During operation, an orange LED inside the housing on the PCB will remain lit. This does not affect the functionality of the device.

6. Preparation for charging

• Carefully read the specifications of the battery and the manufacturer’s instructions. Determine the rated voltage of the battery, which is indicated on the housing or in its documentation.

• If it is necessary to remove the battery from the vehicle for charging or cleaning of terminals, always disconnect the grounded terminal first. Ensure that all vehicle systems are turned off to avoid an electrical arc.

• Clean the battery terminals of dirt and corrosion. Take care to prevent particles from getting into your eyes.

• Check the electrolyte level in the battery. If necessary, add distilled water until the plates are covered (follow the marks on the battery housing).

• Make sure that the selected charging mode corresponds to the recommendations specified in the battery documentation.

7. Charging the battery

• Disconnect all loads from the battery (if the battery is installed in the vehicle, disconnect the negative terminal).

• Set the 6V/12V switch to the required position according to the battery voltage.

• Turn the charging current adjustment knob fully counterclockwise.

• Connect the black clamp of the charger to the negative (-) terminal of the battery.

• Connect the red clamp of the charger to the positive (+) terminal of the battery.

• When correctly connected, the "POWER" and "BATTERY CHARGING" indicators will light up.

• In case of incorrect connection, the "ERROR" indicator will light up. Reconnect the battery to the charger, observing correct polarity.

• Connect the charger to the mains (220 V, 50 Hz). Switch the power to "ON".

• By rotating the current regulator, set the required current value according to the battery capacity.

• The optimal charging current is 10% of the battery capacity. For example, for a 40 Ah battery, it is 4 A. The average full charging time is about 10 hours.

• During charging, the current will gradually decrease. The rate of decrease depends on the condition of the battery.

• Charging is considered complete when the charging current drops to zero or does not decrease within 30 minutes at a value of 0.5–2 A. The "BATTERY FULL" indicator notifies you of completion, and the device will automatically switch off.

8. Constant current source mode

1. Set the current regulator knob to minimum (turn fully counterclockwise).

2. Connect the powered device to the charger clamps. The positive contact (+) corresponds to the red or light-colored clamp, and the negative contact (-) corresponds to the black or dark-colored clamp.

3. Connect the charger to the 220 V mains and switch the power to "ON".

4. When the powered device is turned on, the charger ammeter will display the current consumed by the device.

(!) 5. It is recommended to control the supply voltage with an additional voltmeter.

10. Possible malfunctions and their causes

The green indicator does not light when the battery is connected to the charger

1. Short circuit between charger terminals.
2. Short circuit or open circuit inside the battery.
3. Incorrect battery polarity connection to the charger.
4. Poor contact between charger terminals and the battery.

The green indicator is on, but when the charger is switched on, the charging current is absent or too low and cannot be adjusted

The battery may be deeply discharged or defective. Try to continue charging, and if the current does not increase within one hour, the battery should be disposed of.

The green indicator is on, but the charging current is intermittent, the ammeter needle is fluctuating

This may indicate a battery defect (for example, internal short circuit). If the charging current does not decrease within 10 minutes with the regulator at minimum, the battery should be disposed of.
