Smart microprocessor charger with battery tester and repair function 12V/6A/LCD/Rectifier for AGM LiFePO4 GEL batteries QOLTEC 52488

Universal battery charger – power and diagnostics in one device

This microprocessor-controlled smart charger is a comprehensive solution for anyone who cares about the condition of 12V batteries. Designed for charging and testing lead-acid, AGM, GEL, LiFePO4 and WET batteries, it will be perfect for both car workshops and DIY enthusiasts' garages. Equipped with a clear LCD display, it allows you to monitor the charging process and battery status in real time.

Wide range of applications and compatibility

The Qoltec charger copes perfectly with various types of vehicles – from passenger cars and motorcycles to trucks, boats, lawnmowers and quads. It supports batteries with a capacity of 2Ah to 200Ah. Thanks to six operating modes – car, AGM, GEL, LiFePO4, motorcycle and repair – you can adapt it to the specifics of a particular battery. The repair mode is particularly useful for deeply discharged or long-unused batteries, allowing you to regenerate them and extend their lifespan.

Intelligent charging and safety of use

The charger uses an advanced 3-stage charging process (CC, CV, Float), which optimizes the charging voltage and current depending on the battery's condition. This translates to faster and more efficient charging and longer battery life. Built-in protections – against reverse polarity, overvoltage, short circuit and overheating – guarantee safe operation of the device. Additionally, a cooling fan prevents the charger from overheating during intensive work. Automatic shutdown after full charge protects the battery from overcharging.

Diagnostic functions for professionals and amateurs

The device not only charges batteries, but also allows you to diagnose their condition. You can measure the battery voltage, check the starting current (CCA) and assess its condition and remaining life. This is an extremely useful tool for car mechanics and people who want to independently take care of the efficiency of the battery in their vehicle or garden equipment. A large LCD display ensures easy reading of measurement results and charging parameters.
