## Long description

The QOLTEC 12 V 6 A rectifier with repair function is a mains-powered battery charger designed for charging and maintaining 12 V lead-acid batteries. It delivers up to 6 A of charging current and includes a repair/desulfation mode to help recover batteries affected by sulfation. The charger is intended for automotive, motorcycle and small UPS batteries and supports regular charging cycles as well as long-term maintenance to prolong battery service life.
Advantages
The device combines a stable constant-voltage/constant-current charging profile with a dedicated repair function that applies controlled pulses to reduce sulfation. Built-in protection circuits guard against reverse polarity, short circuit and overcurrent, while the compact mains-powered design enables convenient use in garages, workshops and storage areas. Clear status indicators help monitor charging progress and maintenance operations without requiring technical expertise.

How to use
Connect the charger to the mains supply, then attach the clamps to the battery terminals observing correct polarity (positive to positive, negative to negative). Select the regular charging mode for routine charging or the repair/desulfation mode if attempting to recover a weak or sulfated battery. Monitor the charger indicators to follow the charging progress. Disconnect the charger from the mains after charging is complete and remove the clamps from the battery, starting with the negative terminal.
Usage recommendations
Use the repair/desulfation mode sparingly and only on batteries that show signs of sulfation or reduced capacity. Ensure the battery is in a suitable condition for recovery—severely damaged or leaking batteries should not be serviced. Operate the charger in a well-ventilated, dry environment and follow safety precautions for lead-acid batteries, including eye protection and avoiding sparks near the battery.
