Product information

Description

Battery charger QOLTEC 52491 microprocessor 12V/12.6V/24V with LCD is a compact microprocessor-controlled charger designed to charge and maintain lead-acid batteries. The unit supports 12 V, 12.6 V and 24 V systems and includes an LCD for clear indication of charge status, making it suitable for routine charging, maintenance and monitoring of vehicle and standby batteries in workshops, garages or home environments.

Advantages

Microprocessor control provides automated charge regulation to reduce overcharging and to maintain battery condition during long-term connection. The LCD gives visible feedback on charge status and basic diagnostics, simplifying monitoring without additional tools. Support for multiple nominal voltages (12 V, 12.6 V and 24 V) makes the charger compatible with a range of lead-acid battery systems. The device handles both charge cycles and float (maintenance) modes, allowing continuous connection for battery upkeep.

Suitable for

  • 12 V vehicle batteries and 12.6 V maintenance-capable lead-acid batteries
  • 24 V battery systems used in some vehicles and equipment
  • Maintaining backup and standby lead-acid batteries
  • Use in workshops, garages and home battery upkeep

Key specifications

  • Brand: QOLTEC
  • Model / MPN: 52491
  • EAN: 5901878524917
  • Supported voltages: 12 V, 12.6 V, 24 V
  • Battery type: lead-acid (charging and maintenance)
  • Control: microprocessor-based automated charging
  • Display: LCD for status indication

How to use

Verify the battery type and correct nominal voltage (12 V, 12.6 V or 24 V) before connecting. Attach the charger clamps to the battery terminals observing correct polarity. Power the charger and select the appropriate voltage or mode if selectable; otherwise allow the unit to run its automatic routine. Monitor the LCD for charge progress and wait until the charger indicates charge completion or a maintenance (float) state before disconnecting. Turn the charger off or remove mains power, then remove the clamps, disconnecting the negative terminal first if it is safe to do so.

Usage recommendations

Ensure the charging area is well ventilated and free from sparks or open flames. Clean battery terminals before charging, avoid short circuits, and do not leave the charger connected to damaged batteries. Follow the battery manufacturer’s specifications for voltage limits and maintenance procedures.
