Charger QOLTEC 52493 12V 10A with repair function for AGM batteries

Description: Excellent efficiency thanks to intelligent controlMicroprocessor-controlled charger, guarantees total safety of use, it is personalized charging for each type of battery, automatically when the battery is fully charged, it shuts off keeping the battery ready. So you don't have to worry about overcharging the battery. You can charge your battery safely and quickly now. The product has advanced safety features including reverse polarity, overvoltage and overcharging protection. In addition, a built-in fan protects the device from overheating.Excellent performance through intelligent controlProper selection of the right battery charger is extremely important if you want your battery to serve you for a long time. The wrong charger can result not only in extended charging time, but also a significant reduction in battery life. Qoltec brand charger is microprocessor precision charging, you only need one charger for different types of batteries. The time required for charging depends on the degree of battery discharge and its actual capacity. The charger is designed for charging batteries in cars, motorcycles, boats, lawnmowers, agricultural vehicles and quads.Precise charge management in three stepsThe intelligent Qoltec charger, with its 9-stage automatic charging mode with integrated desulphation and maintenance stage, provides exceptional battery protection and ensures optimum performance.The charging process consists of 9 stages:1. Battery detection2. Battery desulphurisation regeneration, helps to extend the life of the battery being charged3. Soft start - starting charging with a low current, preparation for bulk charging4. Main charging - charging with a constant current5. Absorption charging - charging with a constant voltage6. Regeneration - improving battery durability7. Float charging - when the battery is fully charged, it automatically switches to float mode8. Maintenance - maintaining a full charge9. Switching off Multifunctional LED displayThe charger has a large and clear LED display, making it easy to see the process and the most important charging parameters. You can continuously monitor the status of the battery, check the voltage and amperage and the currently selected mode, making working with the device easy and intuitive, not only for professionals.Repair function or advanced repair of your batteryOur charger is ideal for rescuing a battery that has stopped working as it should, this is usually the result of the battery being completely discharged and left in this state for an extended period. We may then notice that the battery is not accepting the charging current or is heating up significantly. The repair mode is an approximately 16-hour advanced recovery mode for batteries that have not been used for a long time, for example, or for sulphated batteries with very low voltage. With this function, the charger can help extend the life of the battery or regenerate it.Simple installation - robust housingConnecting the charger to the battery is quick and easy, simply attach the clamps to the battery accordingly. The red connector is clipped to the positive terminal and the black one to the negative terminal. Any vehicle owner should be able to cope with this. Once the charger is connected to the power supply and the appropriate mode selected, the charger is ready for charging. | Filters / protection: Surge | Filters / protection: Voltage drop | Filters / protection: Overheating | Filters / protection: Current too high | Filters / protection: Circuit | Special functions: Battery repair function | Batteries included: No | Accessories included: Charger Warranty card Operating instructions | Color: Black | Color: Gray

How to use

Connect the charger to the battery following the manufacturer’s safety instructions: attach the positive clamp to the battery positive terminal and the negative clamp to the negative terminal or a suitable chassis ground. Select the appropriate charging mode for AGM batteries and start the charging cycle. The charger will manage the charging process automatically, switching to maintenance/float mode when the battery reaches full charge. To attempt battery restoration, select the repair/restore function before or during the charge cycle; monitor the battery and charger during the process and follow any device indicators or instructions.

Recommendations

Use the repair/restore function only with AGM batteries and avoid applying repair routines to damaged or leaking batteries. For long‑term storage, keep the charger connected in float/maintenance mode periodically to prevent self‑discharge. Ensure connections are clean and secure and follow basic safety precautions: work in a well‑ventilated area, wear eye protection when necessary, and disconnect the charger before performing any battery maintenance.
