Battery charger QOLTEC 52514 — 12V/24V, 25A, for AGM/GEL/SLA batteries with LCD display

Description: Trust our chargers enjoy uninterrupted powerMicroprocessor-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.A Professional Approach to Optimal Charging and Long-Lasting Battery PerformanceThe charger provides a 6-stage charging process. Each stage is controlled by an electronic circuit, allowing the device to adjust the voltage and current to the current state of the battery. Diagnosis the charger analyses the condition of the battery, Bulk Charge intensive charging with a constant current of 5A until the nominal voltage is reached, Absorption Charge the voltage is maintained at a constant level and the current gradually decreases to avoid overcharging, Float Charge the charger maintains a float voltage, preventing the battery from self-discharging, Trickle Current (pulse charging) Gentle recharging with low current in cycles, which stabilises the voltage and prevents degradation during long periods of inactivity, Monitoring (Stand-by / no load) after full charging, the battery goes into standby mode and is periodically monitored and recharged as needed. 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 housing Connecting 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: Circuit | Filters / protection: Voltage drop | Filters / protection: Overheating | Filters / protection: Current too high | Special functions: Battery repair function | Batteries included: No | Accessories included: Charger Warranty card Operating instructions | Color: Black

How to use

Connect the charger to the correct battery polarity and select the appropriate voltage mode (12V or 24V) according to the battery system in use. Choose the charging profile compatible with AGM, GEL or SLA chemistry via the charger controls. Monitor the LCD to observe voltage, current and charging progress. Allow the charger to complete its automatic charge cycle or stop charging manually when the LCD indicates a fully charged state. Follow standard safety precautions: ensure a well‑ventilated area and secure connections before switching the unit on.

Recommendations

Use the 25A charging mode for batteries rated to accept higher charge currents; for smaller batteries or long‑term maintenance, select a lower current or float/maintain mode if available. Regularly inspect battery terminals and charger connections for corrosion or looseness. Avoid leaving the charger connected unattended for extended periods unless the device specifies a maintenance/float mode designed for continuous connection.
