If you encounter any of these errors, disconnect the battery, check the connections, and try again.
1. Poor contact at the interface (oxidized metal contacts, dust/oil buildup, loose pins).
2. Battery protection mechanisms triggered (over-discharge, over-temperature, etc.).
3. Charging environment temperature outside the safe range (below 5°C or above 40°C).
4. Insufficient load capacity of the power outlet.
We recommend systematically checking these reversible factors first before concluding the charger itself is faulty.
