The charger features multiple operating modes to suit different battery types and conditions. Use the 'MODE' button to cycle through the available options:
- Ụdị 12V: For 12V lead-acid batteries (wet, gel, enhanced flooded, maintenance-free, calcium).
- 12V AGM/SLA Mode: Specifically for 12V AGM and SLA batteries.
- Ụdị lithium 12V: For 12V Li-ion batteries with BMS, including LiFePO4.
- 12V Repair Mode: Extends the life of old, idle, or slightly damaged batteries by removing sulfation and repairing them with pulse repair technology.
- Ụdị 6V: For 6V lead-acid batteries (wet, gel, enhanced flooded, maintenance-free, calcium).
- 12V Supply Mode: Converts to DC power to supply any 12VDC device with a maximum supply current of 2A. Use in excess of 2A is strictly prohibited.

Force Mode for Dead Batteries
If your battery is deeply discharged (down to zero volts) and the charger does not detect it automatically, you can activate Force Mode. To do this, press and hold the 'MODE' button for 7 seconds. This will initiate a forced charge for a short period, after which the charger should revert to normal operation if enough voltage achọpụtara.
6. LED Indicators and Charging Progress
The charger features LED indicators to communicate the charging status and any potential issues:
- Igwe ọkụ na-acha uhie uhie: Indicates the battery is less than 75% charged and is actively charging.
- Igwe ọkụ na-acha akwụkwọ ndụ akwụkwọ ndụ: Indicates the bulk charge is complete, and the battery is being optimized for extended life.
- LED siri ike Green: The battery is 100% charged and the charger is in maintenance mode, providing ongoing optimization.
- Pulsing 100% Charge LED (Maintenance): After the battery is fully charged, the charger will continue to monitor and provide maintenance. The 100% charge LED will pulse slowly during this cycle.
- Ihe ngosi mperi: The charger also has indicators for error conditions such as a bad battery, reversed positive/negative connections, or voltage over 15V. Refer to the included user manual for specific error code explanations.
5-Step, 4-Stage Smart Charging Process
The charger utilizes an intelligent 5-step, 4-stagusoro ịchaji:
- Step 1: Pre-charge
- Step 2: Charge Detection and Diagnosis
- Step 3: Constant Current Charging
- Nzọụkwụ 4: Constant Voltage Nchaji
- Step 5: Trickle Maintenance Charging

Ụgwọ okpomọkụ
The integrated digital thermal sensor detects the ambient temperature and alters the charge to eliminate over-charging in hot climates (e.g., 45°C / 113°F) and under-charging in cold climates (e.g., -20°C / -4°F). This ensures stable performance, low heat generation, and high efficiency across different environmental conditions.
