Smart 12V 15A Charger QOLTEC with Microprocessor and LCD — for AGM, GEL, SLA, EFB, LiFePO4 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 desulphurisation regeneration, helps to extend the life of the battery being charged2. Soft start - starting charging with a low current, preparation for bulk charging3. Main charging - charging with a constant current4. Absorption charging - charging with a constant voltage5. Float charging - when the battery is fully charged, it automatically switches to float mode6. Battery test - checking the charge level and condition7. Regeneration - improving battery durability8. Maintenance - maintaining a full charge9. Maintenance - low current to maintain full chargeMultifunctional LED display, touch MODE butonThe charger has a large and easy-to-read LCD display, making it easy to view the charging process and key parameters. You can constantly monitor the battery status, check the voltage and current, and the currently selected mode, making working with the device easy and intuitive, not only for specialists. Thanks to the touch-sensitive MODE button, operating the charger is even simpler and more intuitive. A light touch is all it takes to switch between operating modes, including activating the power supply (SUP) function or forced charging.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.Indispensable when replacing the batteryWhen switched to SUP (Supply) mode, the charger can operate as a stabilised 14V power supply, ideal for maintaining the vehicle's electrical system during battery replacement to protect data and settings in electronic systems. It maintains a constant 14V voltage in the car's electrical system, protecting against loss of settings for the on-board computer, radio, electric windows and other systems.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: Current too high | Filters / protection: Circuit | Filters / protection: Overheating | Special functions: Battery repair function Power supply function Child lock function | Batteries included: No | Accessories included: 1 x Charger 1 x Warranty card 1 x Operating instructions | Color: Black | Color: Blue

How to use

Verify the battery is a 12V type and that the chemistry is supported (AGM, GEL, SLA, EFB or LiFePO4). Connect the charger to the battery following the product manual and the battery manufacturer’s safety instructions, then switch the unit on. Use the LCD and the control interface to select the appropriate charging mode for the battery type. Monitor the LCD for progress and status messages while the microprocessor manages the automated charging stages. After charging or maintenance is complete, disconnect the charger according to the manual.

Recommendations

Use the charger in a dry, well-ventilated area and follow the battery manufacturer’s guidelines for temperature and charging limits. Regularly inspect battery terminals and charger leads for secure connections and signs of damage. For long-term storage, use the maintenance mode to keep batteries at nominal charge and consult the battery documentation for recommended intervals and precautions.
