Product description: Microprocessor charger - rectifier for AGM / GEL / LiFePO4 batteries - 12 V 15 A - Qoltec 52496
The Qoltec microprocessor charger for 12V batteries with a charging current of up to 15A is a modern device for safely charging and maintaining batteries used in vehicles and consumer equipment. Thanks to microprocessor control, the charger automatically monitors operating parameters , reducing the risk of overcharging, reverse polarity, short circuit, overvoltage, overheating, and low voltage. The model is equipped with an LCD display that allows you to monitor voltage, current, battery condition, and the selected operating mode. The repair function supports the regeneration of long-unused or deeply discharged batteries , while the 14V SUP mode allows you to maintain the vehicle's electrical system during battery replacement , protecting the on-board electronics settings.

The Qoltec microprocessor charger will prove useful in garages, car workshops, farms and when servicing seasonal vehicles.
Main features of the charger
- Microprocessor control : automatically selects and controls charging parameters, increasing the safety of working with the battery
- Charging current 15 A : enables efficient charging of 12 V batteries with a capacity of 2 Ah to 220 Ah
- 9-step charging process : includes desulphation, soft start, main charge, absorption, test, regeneration, maintenance and float
- Repair function : supports the recovery of long-unused, sulphated or deeply discharged batteries
- SUP 14V mode : allows you to maintain the voltage in the car installation while replacing the battery
- Multiple battery support : compatible with AGM, GEL, SLA, EFB, WET, lead-acid and LiFePO4 batteries
- LCD display : provides a convenient view of charging parameters and the selected operating mode
- Touch-sensitive MODE button : makes it easy to switch modes, including activating the power adapter or forced charging function
- Built-in fan : helps protect the device from overheating during operation
- Advanced safety features : protection against reverse polarity, overvoltage, short circuit, overheating, low voltage, overload and overcharge
9-step battery charging process
The charging process in the Qoltec charger is divided into nine stages to best match the device's operation to the current battery condition. The charger begins with desulfation and soft start , then moves through main and absorption charging , and once the appropriate energy level is reached, activates test, regeneration, maintenance, and sustain modes . This helps improve battery performance, reduce the risk of overcharging, and keep it ready to use for longer. This is especially important for seasonal batteries used in motorcycles, boats, ATVs, campers, and garden equipment.

The charger is equipped with an LCD display that allows you to monitor voltage, current, battery status and the selected operating mode.
