About this item

• 【Heavy Duty Battery Charger】This smart battery charger features a durable metal outer frame combined with a high-strength ABS plastic housing, offering both protection and portability. Weighing 14.3 lbs, it's built to withstand tough garage conditions while remaining easy to handle. Compatible with all 12V and 24V lead-acid batteries—AGM, GEL, Wet (Flooded), EFB, Calcium, MF, and deep-cycle. Perfect for charging cars, trucks, motorcycles, RVs, ATVs, and lawn mowers. Longer Cables, Greater Flexibility – AC: 6.6 ft | DC: 4.9 ft.
• 【Smart Dual-Mode Charging – Fast or Trickle】Automatically detects 12V or 24V batteries and adjusts charging accordingly. With a 0–15A output and support for up to 400Ah, this charger offers both rapid charging to revive dead batteries and trickle mode to maintain long-term battery health—just connect it and let it do the work.
• 【Upgraded 10 Charging Modes】Expanded from 6 to 10 modes, including CV (constant voltage) and CC (constant current) modes. CV mode ensures stable full charging while helping reduce battery stress, gas generation, and water loss. CC mode delivers faster charging when quick power recovery is needed. Also features Energy-Saving Mode for efficient low-power charging based on battery status, and Strong Mode for continuous full-output charging.
• 【Winter / Summer Mode】In cold weather, the winter mode delivers a complete charge to ensure a strong engine start. The all-weather mode (Summer mode) is designed to provide reliable charging performance in any climate, adapting to temperature changes for consistent battery care. The easy-to-read LCD display shows charging percentage, current, and voltage for precise, safe, and efficient charging all year round.
• 【Repair & Battery Maintenance 】Repair Mode is specially designed to revive dead batteries above 3 V, helping restore battery life and get your vehicles back on the road. It can assist in recovering batteries that do not charge normally, though it cannot revive severely depleted batteries. Automatic Shut-Off stops charging once the battery is full to prevent overcharging, while Maintain Mode uses pulse current to extend the life of drained, sulfated, or stratified batteries.
• 【More Than a Battery Charger】Dual-use design for battery charging and 12V DC power supply, making it suitable for use in garages, workshops, and outdoor environments. It also supports compatible 12V electrolysis rust removal systems by providing stable DC power for various DIY and maintenance applications.
• 【Safety Protections】This 12/24V battery charger includes multiple built-in safeguards such as reverse polarity, short circuit, overcharge, overheat, over-voltage, and over-current protection. A built-in cooling fan helps prevent overheating, while spark-free connections ensure safe handling. These features guarantee a secure and efficient charging process that protects your battery and vehicle. Includes a 3-year warranty for long-term reliability.
