The 12V 120Ah Intelligent Auto Cut-Off Smart Battery Charger is a high-efficiency power solution engineered for safely charging heavy-duty lead-acid, gel, and dry-cell batteries. Featuring a durable, lightweight green composite outer shell, it delivers a precise charging curve optimized for high-capacity applications like easy-bikes, electric rickshaws (Mishuk), personal vehicles, and emergency power supply (UPS) setups. Equipped with state-of-the-art microprocessing technology, it provides hands-free charging operation while completely mitigating the risks of human error or cell damage.

• Automated Pulse Repair (PWM Technology): Uses advanced Pulse Width Modulation to effectively restore battery health, dissolve light sulfation, and extend overall service life.
• Intelligent Auto Cut-Off: Constantly monitors the battery voltage and automatically stops or enters a micro-current trickle charge mode once the cell reaches maximum capacity, preventing dangerous overcharging and bloating.
• Active Cooling System: A high-speed internal cooling fan actively expels heat during high-load operations to maintain continuous efficiency and structural lifespan.
• Dual LED Indicators: Instantly read real-time status with designated indicators for Power and Charging / Full Status.

• Reverse Polarity Protection: Prevents short-circuiting or spark hazards if the clamps are mistakenly connected to the wrong terminals.
• Over-Current & Over-Voltage Protection: Regulates incoming current fluctuations to feed a smooth, stable stream into your hardware.
• Short-Circuit Shield: Instantly shuts down the electrical output in case of an abrupt power fault or wiring failure.

• Input Voltage: AC 220V / 50Hz (Standard wall outlet)
• Output Voltage: DC 12V
• Maximum Battery Capacity Compatibility: Up to 120Ah (Supports lower ranges down to 20Ah smoothly) [1]
• Compatible Battery Chemistries: Lead-Acid, Sealed Maintenance-Free (SMF), Gel, AGM, Dry-Cell [3]
• Housing Material: Heavy-duty, heat-resistant ABS Polymer
• Connections Included: 1x Attached AC Power Cable, 2x Heavy-Duty Color-Coded Insulated Alligator Clamps (Red Positive / Black Negative)

1. Ensure the AC power cord is unplugged from the wall outlet before connecting anything to the battery.
2. Securely hook up the Red Alligator Clip to the positive (+) terminal of your 12V battery.
3. Attach the Black Alligator Clip to the negative (-) terminal of your 12V battery.
4. Plug the AC cord into your standard wall switch to initiate charging.
5. When the indicator turns green (signaling Full), unplug the AC outlet first, then disconnect the battery clamps.
