Intelligent 12 V 6 A battery charger and tester with LCD and repair function for AGM, GEL and LiFePO4
Intelligent 12 V 6 A battery charger and tester with LCD and repair function for AGM, GEL and LiFePO4
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
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
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
