5. Иштөө нускамалары
The charger automatically detects the battery type and initiates the appropriate charging process. The display panel provides status indicators.
5.1. Charging Process Indicators

Image: The charger's display panel indicating "0-50%" and "50-100%" charge levels, along with "Lead Acid" and "Lithium (LiFePO4)" indicators.
- 0-50% Light ON: Battery is charging and is below 50% capacity.
- 50-100% Light ON: Battery is charging and is between 50% and 100% capacity.
- Both 0-50% and 50-100% Lights ON: Battery is fully charged, and the charger has switched to float mode.
- Lead Acid Light ON: Charger is operating in Lead-Acid battery mode.
- Lithium (LiFePO4) Light ON: Charger is operating in Lithium battery mode.
- Abnormal Light ON: Indicates a fault (e.g., reverse polarity, short circuit, damaged battery). Disconnect and check connections.
5.2. Төмөн-томtage Repair Mode
This mode is specifically for 12V lead-acid batteries with voltage lower than 8V. It attempts to restore deeply discharged batteries.
- Connect the charger to the low-voltage 12V lead-acid battery as described in Section 4.
- басып, кармап туруңуз РЕЖИМ баскычын 3 секунда басыңыз.
- The charger will enter low-voltage charging mode. The repair process is completed when both the 0-50% and 50-100% lights are ON.
Кеңеш: Эгерде батареянын томtage is lower than 4V, it is generally recommended to replace the battery as it may be beyond repair.

5.3. Automatic Float Charging
Once the battery is fully charged, the charger automatically switches to float mode. In this mode, it maintains the battery at an optimal charge level without overcharging, preventing sulfation and extending battery life. This allows the charger to be left connected indefinitely.
