The QOLTEC smart charger for 12V and 24V batteries offers microprocessor control, safe and fast charging, and automatic maintenance of full capacity. With multiple modes for CAR/AGM/MOTO and a Repair function, it helps restore deeply discharged or sulfated batteries. The large LCD display shows voltage, current, temperature, and the selected mode; protections against reverse polarity, overvoltage, and overcharge and an active fan ensure maximum safety.
Smart 3-stage charging for longer battery life

Smart 3-stage charging for longer battery life

The CC/CV/FLOAT algorithm automatically adjusts voltage and current to the battery’s condition, shortens charging time, and prevents overcharging.

Repair function for regenerating deeply discharged batteries

Repair function for regenerating deeply discharged batteries

An approximately 16-hour recovery mode helps revive sulfated or long-inactive batteries and can extend their service life.

Large LCD display and multi-mode operation 12V/24V

Large LCD display and multi-mode operation 12V/24V

The clear display shows voltage, current, and temperature; CAR/AGM/MOTO/REPAIR modes make it easy to choose the right option for each battery type.

This intelligent charger is ideal for cars, motorcycles, ATVs, boats, lawn mowers, and agricultural machinery. It supports 12V (max. 8A) and 24V (max. 4A) batteries, including AGM and GEL types. The microprocessor optimally manages the charging process and switches to maintenance mode after reaching full capacity, preventing overcharging.

Smart 3-stage charging works in steps CC (fast charge up to about 80%), CV (stable voltage 14.1–14.8 V with decreasing current), and FLOAT (maintaining 13.0–13.8 V to reach 100%). The Repair function initiates an approximately 16-hour regeneration cycle for long-discharged or sulfated batteries, which can extend their lifespan.

The large LCD/LED display makes it easy to monitor voltage, current, temperature, and modes (CAR/AGM/MOTO/REPAIR). Connection is quick: red clamp to + pole, black to – pole. Safety is ensured by protections against reverse polarity, overvoltage, overcharge and overheating thanks to the built-in fan.

  • Universal use: 12V/24V for cars, motorcycles, boats, and more.
  • Life optimization: smart 3-step charging + maintenance.
  • Battery recovery: Repair mode for deeply discharged batteries.
  • Maximum safety: multi-level protections and fan.
  • Convenient operation: clear display and intuitive controls.
