1. Unpacking: Verify all accessories including operation manual
2. Pre-power Inspection: Check for damage, moisture, loose screws, or abnormal appearance after storage/transport
3. Wiring: Connect power cord according to marked specifications
4. Setting: Fan operates in temperature control mode, activating when reaching starting point. Charger stops at 70-75°C and resumes automatically when temperature decreases

1. Wiring: Connect power supply and load. Ensure correct positive/negative electrode connection to prevent damage
2. Power On: LCD panel illuminates - adjust knob to set voltage and current

Conventional Charging: Charging current selected based on 10-hour charging rate:
Charging Current (A) = Battery Rated Capacity (Ah) ÷ 10(h)
Example: 200Ah battery = 200Ah ÷ 10h = 20A

Fast Charging: Battery Capacity (AH) ÷ Required Charging Time = Selected Charging Current (A). Charging complete when display shows 0A. Can maintain trickle/floating charge while powered on.

Online Charging: Current selected per conventional method. Suitable for charger → battery → load (or engine) connected configurations, ideal for unattended operation.

Charger operates until completion, with LCD displaying 100% capacity and 0A current indicating full charge. Can then shut down or maintain trickle/floating charge.

• Frequency Conversion Combined Pulse: Intelligent pulse interference during charging process disrupts battery vulcanization and crushes lead sulfate crystal nuclei
• Temperature Compensation: Precise temperature monitoring via thermistor electronics with intelligent voltage adjustment to prevent undercharge/overcharge

Deligreen car charger can extend lead acid battery life by up to 2 years.

• Temperature Compensation: Precise voltage control below polarization point (floating charge stage: 2.42V-2.45V per cell)
• Variable Frequency Combined Pulse: Multi-frequency pulses combined to optimize charging and depolarization performance, reducing resistive, concentration, and electrochemical polarization

Frequency conversion pulse charging reduces water loss to one-third of conventional chargers. Reduced water loss minimizes battery pack voltage differential. Combined pulse charging with small water loss and minimal voltage difference helps maintain battery pack balance through vulcanization removal.

This charger supports both lithium battery and lead acid battery charging applications.

• Compact dimensions with high IP66 protection rating
• High charging efficiency: 85% standard, up to 99% with PFC
• Soft-start pre-charge: Gradual current rise prevents battery damage from high-current impact
• Pulse repair charging for over-discharged batteries: Special pulse treatment for voltages as low as 2.8V before switching to normal charging mode
