The QOLTEC smart charger for 12 V batteries offers microprocessor control, 6 operating modes, and a Repair function to regenerate weak batteries. Thanks to the large LCD display, you can easily monitor voltage, current, and the selected mode. The charger is suitable for AGM, GEL, and LiFePO4, can test the battery (voltage, CCA, condition), and provides comprehensive protections against reverse polarity, overvoltage, overheating, and short circuit.
Six intelligent modes for every battery type

Six intelligent modes for every battery type

Choose the ideal program: Auto (Pb), AGM for start/stop, GEL, LiFePO4, Moto for smaller batteries, and Repair for restoring capacity. One charger for multiple uses.

Battery testing and clear LCD display

Battery testing and clear LCD display

The large LCD shows voltage, charging current, and mode. The built-in tester measures voltage, CCA, and battery condition, helping you pinpoint issues without costly diagnostics.

Safe, fast, and gentle charging

Safe, fast, and gentle charging

The microcontroller manages three-phase charging CC/CV/FLOAT and protects against reverse polarity, overvoltage, overcurrent, short circuit, and overheating. An integrated fan ensures stable operation.

Looking for a universal and safe way to keep your battery in perfect condition? The QOLTEC intelligent charger with 6 A output combines precise microprocessor control, a clear LCD display, and top-tier protections. It supports multiple battery types including AGM, GEL, and LiFePO4, so you can charge cars, motorcycles, boats, and garden equipment with a single device.

With the testing functions, you can quickly determine the real state of the battery—measuring voltage, CCA starting current, and overall condition. The special Repair mode helps restore long-discharge or sulfated batteries. Three-phase charging CC/CV/FLOAT ensures fast, gentle, and fully automatic charging without the risk of overcharging.

  • 6 modes: Auto (Pb), AGM, GEL, LiFePO4, Moto, Repair
  • Safety: reverse polarity, overvoltage, overcurrent, overheating, short circuit, low voltage
  • Easy operation: large LCD, clear display of voltage, current, and mode
  • Maintenance and long service life: maintenance (FLOAT) phase keeps the battery ready to use
