The core of preventing battery failures in 2-ton electric forklifts lies in standardized charging, scientific usage, and regular maintenance, which helps avoid issues such as over-discharging, corrosion, and abnormal charging from the source.

I. Standardize the Charging Process (The Most Critical Preventive Measure)

1. Follow the principle of "charge as you use". Stop operation and charge immediately when the battery level drops below 20% to avoid battery damage caused by deep discharge.
2. Use the original charger that matches the battery model (e.g., 48V/60V for corresponding batteries). Mixing chargers of different specifications is prohibited.
3. Clean the battery terminals before charging to remove dust and oil stains, preventing overheating or insufficient charging due to poor contact.
4. Maintain good ventilation in the environment during charging. Keep away from fire sources and flammable materials, and do not cover the charger or battery to prevent overheating.
5. Control the charging duration. A lead-acid battery only needs 8-10 hours of single charging. Disconnect the power promptly after full charging to avoid overcharging.

II. Develop Scientific Usage Habits

1. Avoid long-term full-load operation or frequent rapid acceleration and sudden braking. This reduces the battery's instantaneous high-current discharge and extends its service life.
2. Reduce the operation intensity in low-temperature environments (below 5℃). Preheat the battery to room temperature before charging to avoid low charging efficiency and battery damage caused by low temperatures.
3. Do not modify the battery without authorization or add external devices, as this may cause circuit overload and lead to battery short circuits.

III. Regular Maintenance and Inspection

1. Inspect the battery's appearance daily. If electrolyte leakage (for lead-acid batteries), terminal oxidation, or shell damage is found, handle it immediately.
2. Wipe the battery surface and terminals with a dry cloth every week. For severe oxidation, gently polish with sandpaper and then apply a small amount of Vaseline for rust prevention.
3. For lead-acid batteries, check the electrolyte level every 1-2 months. Add distilled water (do not add tap water or electrolyte) when the level is below the scale line, and keep the level between the upper and lower scales.
4. Check the charger's working status monthly. Observe whether the charging indicator light functions normally (red light on when powered on, green light on after full charging). ｒｅｐｌａｃｅ the charger promptly if any abnormality is found.

IV. Environmental and Storage Requirements

1. Store the battery in a dry, ventilated, and cool area. Avoid direct sunlight or exposure to rain to prevent moisture-induced corrosion or damage caused by thermal expansion and contraction.
2. For long-term non-use (more than 15 days), fully charge the battery first, then supplement the charge every 15 days to maintain the battery level between 50% and 80%.
3. Disconnect the main battery switch during storage to prevent power loss caused by standby power consumption of the equipment.
