Battery failure is the main cause of downtime for electric forklifts, especially in long-term use. Common problems include insufficient endurance, slow charging, bulging battery, and voltage abnormality.
For insufficient endurance, first check whether the battery is aging. Generally, the service life of a lithium battery is about 1500–2000 charging cycles. If the actual working time is significantly shortened, the battery may need to be replaced. At the same time, check whether the charging pile is normal and whether the charging contact is loose or oxidized.
Slow charging is usually caused by poor contact between the charging plug and socket, or damage to the battery management system (BMS). Clean the contact surface and check the charging line for damage. If the problem persists, the BMS or charger may need professional testing.
Battery bulging is a serious fault, usually caused by overcharging, high-temperature environment, or internal short circuit. Once bulging is found, stop using it immediately and replace the battery to avoid safety hazards such as leakage or fire.
Daily maintenance includes keeping the battery surface clean and dry, avoiding overcharging and deep discharging, and placing the forklift in a cool and ventilated place. Regular battery inspection can effectively reduce failures and extend service life.
