Smart Car Battery Charger 12V/24V 6A with LCD Display, Automatic Voltage Detection and Pulse Repair Mode for Lead-Acid Batteries

Introduction

• Keep compatible 12V and 24V lead-acid batteries ready for use with a compact 6A charger designed for cars, motorcycles, trucks and other battery-powered equipment.
• Automatic 12V/24V detection reduces setup steps, while the front LCD provides useful charging information at a glance.
• Standard charging, float charging and pulse repair functions support routine battery care as well as selected long-idle or under-voltage lead-acid batteries.
• A ventilated housing, built-in cooling fan, thick cables and copper-coloured alligator clamps provide a practical charging setup for the garage or workshop.

Key Features

• Automatic 12V/24V Detection: The charger identifies a compatible 12V or 24V lead-acid battery and selects the appropriate voltage system, reducing the need for manual voltage switching.
• 6A Charging Output: Suitable for routine charging and maintenance of compatible lead-acid batteries with capacities up to 150Ah.
• LCD Charging Information: View battery level or charging progress, detected voltage and charging current from the front display instead of relying only on basic indicator lights.
• Pulse Repair Mode: High- and low-frequency pulse processing is designed to help improve charging acceptance in some long-idle, under-voltage or lightly sulfated lead-acid batteries. Results depend on battery condition and the function cannot restore a physically damaged or failed battery.
• Lead-Acid Battery Compatibility: Designed for compatible flooded lead-acid, maintenance-free and dry lead-acid batteries used in cars, motorcycles, trucks and similar equipment.
• Built-In Cooling Fan: The rear fan and upper ventilation channels help manage operating heat during charging. Keep the ventilation openings uncovered during use.
• Secure Battery Connections: Red and black copper-coloured alligator clamps use strong jaws and thick connecting cables for a firm connection to the correct battery terminals.
• Compact Workshop Design: The approximately 17 × 15 × 8cm body is easy to position near a vehicle and compact enough for storage when not in use.
• Wide AC Input Range: AC 140–220V input supports operation across a broad mains-voltage range when the available supply remains within the rated specification.

Additional Benefits

• Clear front-panel markings make charging, float charging, reverse-connection status, 12V/24V detection and repair functions easier to identify.
• Approximately 90cm power cable provides practical reach from a nearby outlet.
• Integrated power and clamp leads keep the essential connections together with the charger.
• The rugged black-and-yellow housing protects the controls and provides a stable tabletop form.
• Separate charge and repair controls allow the operating function to be selected directly from the front panel.

Why Choose This Product?

• One charger for two common voltage systems: Use the same unit with compatible 12V and 24V lead-acid batteries.
• More information while charging: The LCD helps you follow voltage, current and charging progress in real time.
• Useful for routine care and selected recovery attempts: Standard, float and pulse repair functions cover more than basic charging alone.
• Built for practical vehicle use: Strong clamps, cooling ventilation and a compact housing suit garages, home maintenance and workshop use.

Tips for Better Results

• Confirm that the battery is a compatible 12V or 24V lead-acid type before connecting the charger. Do not use it with lithium batteries.
• Keep the charger disconnected from AC power while attaching or removing the battery clamps. Connect red to positive (+) and black to negative (-).
• Charge in a dry, well-ventilated location away from flames, sparks and flammable materials. Never cover the fan or ventilation openings.
• Check the charger, clamps and battery periodically during use. Stop immediately if the battery swells, leaks, freezes, becomes unusually hot, smells abnormal or shows physical damage.
• Pulse repair results vary with battery age and condition. It cannot repair internal shorts, broken plates, leakage, swelling or other physical failure.
• Disconnect AC power before removing the clamps after charging, then remove the negative clamp followed by the positive clamp.
