About this item

  • For 12V & 24V Lead-Acid and LiFePO4 Batteries: Engineered for versatility and performance, this Battery Charger is compatible with all 12V and 24V lead-acid batteries (Flooded, AGM, GEL, EFB, SLA) as well as LiFePO4 lithium batteries equipped with a BMS system (14.6V/29.2V±0.2V). Ideal for charging and maintaining batteries in cars, trucks, SUVs, motorcycles, lawn mowers, boats, marine equipment, and agricultural machinery. Note: Compatible with 12V batteries from 2Ah to 300Ah and 24V batteries from 2Ah to 150Ah. Not suitable for LiFePO4 batteries without a BMS, physically damaged batteries, non-rechargeable batteries, or batteries with no voltage.
  • 9-Stage Smart Charging & Auto-Memory: Equipped with a microprocessor-controlled 9-stage charging process (Battery Detection, Desulfation, Half-Power Constant Current, Full-Power Constant Current, Constant Voltage Charging, Repair, Float Charge, Battery Maintenance, and Power Off), this charger automatically diagnoses, charges, and maintains your battery to maximize its lifespan and ensure optimal performance. The built-in Auto-Memory function intelligently remembers your last selected mode, it automatically resumes charging with the same settings. It automatically detects 12V or 24V battery systems upon connection and adjusts the charging parameters accordingly.
  • Adjustable 1-20A Battery Charger: Unlike standard fixed-rate chargers, this 12V 20A / 24V 10A smart charger allows you to manually adjust the charging current from 1A to 20A to perfectly match your battery's specific needs. Whether you're gently charging a small 12Ah motorcycle battery with low current or rapidly reviving a large truck battery at full 20A, the choice is yours. This precision charging ensures optimal efficiency, prevents overcharging, and significantly extends battery lifespan. For Old battery, manually reduce current when internal resistance increases to avoid premature "fully charged" misjudgment.
  • Multi-Protection + Temperature Compensation: Safety first! This smart battery tender features reverse connection buzzer alarm, overcurrent, overcharge protection, overvoltage, and short-circuit protection. Charging Efficiency Optimization ensures faster, smarter charging, while Trickle mode provides long-term maintenance at or below the 0.1C rate—to reduce polarization and extend battery life.The intelligent temperature compensation system automatically adjusts charging parameters based on ambient temperature (Winter mode <10℃, Summer mode >28℃), ensuring safe and optimal charging in hot or cold climates. The built-in cooling system prevents overheating during high-current charging.
  • User-Friendly Design with Large LCD Screen: The sunlight-readable LCD screen displays real-time charging status: voltage, current, temperature (℉/℃), charging percentage, and battery status. The touch key automatically locks 25 seconds after charging starts to prevent accidental mode changes — simply disconnect a clip or AC power to unlock. The charger features a smart sleep mode — screen turns off 30 minutes after charging completes to save energy and extend LED life. The 4.9ft input cable and 3ft output cable provide flexible reach, and the built-in storage compartment keeps cables and clips neatly organized.
  • 6 Smart Modes + Pulse Repair for Any Battery Need: Choose effortlessly from 6 specialized charging modes—Standard, LiFePO₄, Start/Stop-GEL, Motorcycle/Hanging Charge, Load Mode, and Repair Mode—each precisely tailored to your battery type and condition. Whether you're maintaining a classic car battery, optimizing a BMS-equipped LiFePO4 lithium battery, or refreshing a start-stop system AGM battery, there's a mode designed for optimal performance and safety.Perfect for reviving aged or underperforming batteries, repair Mode offers a practical second chance before considering replacement.
