Extending the lifespan of electric forklift batteries requires a multi-faceted approach, including charging management, daily maintenance, operating habits, and environmental control. Here are some specific suggestions:

I. Charging Management: Avoid Overcharging and Over-discharging

Lead-acid batteries: Charge when the remaining capacity is no less than 30%, avoiding deep discharge. Use constant voltage charging at the end of the charging cycle to reduce the risk of overcharging.

Lithium batteries: Charging and discharging current and voltage must meet manufacturer requirements, avoiding overcharging and over-discharging. For daily use, charge to 70%-80%, and after a full charge for long-distance use, reduce the charge to within 80% as soon as possible.

II. Daily Maintenance: Regular Inspection and Cleaning

Electrolyte level: Check the electrolyte level monthly. If it is below 10mm from the lead grid, add distilled water or deionized water. Use a battery watering gun to control the electrolyte level.

Cleaning and inspection: Clean the battery casing and terminals monthly, removing dust and oxides. Calibrate the battery with a full charge every 1-2 months. Check the battery health every six months. If the voltage difference between single cells of a lead-acid battery exceeds 0.3V, or the internal resistance of a lithium battery exceeds 50mΩ, contact after-sales service.

III. Operating Habits: Avoid Extreme Use

Charging timing: After use, the battery is at a high temperature; let it sit for 30 minutes to 1 hour before charging. In low-temperature environments in winter, move the vehicle to a warm indoor environment for half an hour before charging.

Avoid sudden acceleration and braking: Reduce instantaneous high-current discharge from the battery to protect the battery structure.

IV. Environmental Control: Suitable Temperature and Storage

Storage environment: The temperature should be between 20℃ and 25℃, with good ventilation, dryness, and avoidance of direct sunlight. When the battery is not in use for a long time, keep it fully charged and perform regular charging maintenance.

Extreme weather: Avoid charging in direct sunlight in summer, and prevent the battery from being in sub-zero temperatures for extended periods in winter.

V. Safety and Maintenance

Safety management: The charging area should be well-ventilated and away from fire sources. Operators should wear protective equipment and comply with safety regulations.
