Product information

Description

QOLTEC 52514 is a battery charger for 12V and 24V lead‑acid batteries, delivering up to 25A of charging current. Compatible with AGM, GEL and SLA battery types, it includes an LCD display that shows charging status and parameters. The charger provides selectable voltage modes and monitoring features designed for vehicle, marine and stationary battery maintenance and charging.

Advantages

The charger supports both 12V and 24V systems and provides a high‑current output of up to 25A for faster recharge of suitable batteries. Compatibility with AGM, GEL and SLA chemistries ensures correct charging profiles for common lead‑acid battery types. An integrated LCD display presents real‑time information about voltage, current and operating mode, simplifying monitoring and adjustment. Selectable voltage modes and protective design reduce the risk of overcharging and support long‑term battery upkeep.

Suitable for

  • Charging and maintaining 12V and 24V vehicle batteries (cars, vans, trucks)
  • Marine battery charging and maintenance on boats and yachts
  • Stationary lead‑acid battery systems in workshops, garages and backup power setups
  • Reconditioning or topping up AGM, GEL and SLA batteries used in mobility devices and small machinery

Key specifications

  • Output voltage: selectable 12V / 24V
  • Maximum charging current: 25 A
  • Battery types supported: AGM, GEL, SLA (lead‑acid)
  • Display: LCD for status and parameter readout
  • Modes: selectable charging/voltage modes for appropriate battery profiles
  • Application: vehicle, marine and stationary battery charging and maintenance

How to use

Connect the charger to the correct battery polarity and select the appropriate voltage mode (12V or 24V) according to the battery system in use. Choose the charging profile compatible with AGM, GEL or SLA chemistry via the charger controls. Monitor the LCD to observe voltage, current and charging progress. Allow the charger to complete its automatic charge cycle or stop charging manually when the LCD indicates a fully charged state. Follow standard safety precautions: ensure a well‑ventilated area and secure connections before switching the unit on.

Usage recommendations

Use the 25A charging mode for batteries rated to accept higher charge currents; for smaller batteries or long‑term maintenance, select a lower current or float/maintain mode if available. Regularly inspect battery terminals and charger connections for corrosion or looseness. Avoid leaving the charger connected unattended for extended periods unless the device specifies a maintenance/float mode designed for continuous connection.
