Battery charger QOLTEC 52491 microprocessor 12V/12.6V/24V with LCD

Description: Excellent efficiency thanks to intelligent controlThe proper selection of an appropriate charger for the battery is crucial if you want your battery to serve you for a long time. The wrong charger can result not only in longer charging times, but also in a significant reduction in battery life.The Qoltec charger offers microprocessor precision in charging one charger is all you need for various battery types with capacities ranging from 4Ah to 105Ah. Perfect for AGM, GEL, WET, SLA, and LiFePO4 batteries. The charging time depends on the battery's discharge level and its actual capacity.Trust our chargers - enjoy uninterrupted energyRectifier microprocessor-controlled, guarantees absolute safety of use, personalised charging for each type of battery, automatically switches off when the battery is fully charged, keeping the battery ready to use. So you don't have to worry about overcharging the battery. You can now safely and quickly recharge your battery. Product has advanced security features including reverse polarity, overvoltage and overcharge protection. Additionally built-in fan protects the device from overheating.A Professional Approach to Optimal Charging and Long-Lasting Battery PerformanceThe charger uses an intelligent 4-stage charging process that adjusts the voltage and current based on the battery's current charge state, ensuring optimal performance and care for the battery at each stage. It consists of four stages:Constant Current (CC): The charger delivers a constant current to the battery while the voltage gradually increases.Constant Voltage (CV): The charger maintains a constant voltage while the current decreases as the battery nears full charge.Maintenance Charging: A low, continuous current keeps the battery fully charged, compensating for self-discharge.Float Charging: A lower voltage is applied to keep the battery fully charged without the risk of overcharging, ideal for long-term maintenance.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: Current too high | Filters / protection: Overheating | Filters / protection: Overcharging | Filters / protection: Reverse polarity | Filters / protection: Surge | Filters / protection: Circuit | Filters / protection: Voltage drop | Special functions: Battery repair 4-stage charging mode | Batteries included: No | Accessories included: 1 x Charger 1 x Warranty card 1 x User manual | Color: Black

How to use

Verify the battery type and correct nominal voltage (12 V, 12.6 V or 24 V) before connecting. Attach the charger clamps to the battery terminals observing correct polarity. Power the charger and select the appropriate voltage or mode if selectable; otherwise allow the unit to run its automatic routine. Monitor the LCD for charge progress and wait until the charger indicates charge completion or a maintenance (float) state before disconnecting. Turn the charger off or remove mains power, then remove the clamps, disconnecting the negative terminal first if it is safe to do so.

Recommendations

Ensure the charging area is well ventilated and free from sparks or open flames. Clean battery terminals before charging, avoid short circuits, and do not leave the charger connected to damaged batteries. Follow the battery manufacturer’s specifications for voltage limits and maintenance procedures.
