Lithium battery forklift battery maintenance guide: BYD P20SII battery maintenance instructions

The battery of a lithium forklift is the core of the stable operation of the equipment. The P20SII model lithium battery is widely used, but improper maintenance will greatly shorten the lifespan. The following is a comprehensive maintenance guide to help you scientifically maintain the battery and improve the efficiency of the equipment.

Daily charging and maintenance points

Correct charging process: Make sure the surface of the battery is dry and free of debris before charging. Connect the charger after turning off the power supply of the forklift, and align it with the positive and negative interfaces to avoid reverse connection. Keep the environment ventilated during charging and stay away from the high temperature of the open flame. The charger shows that it is fully charged and then let it stand for 10-15 minutes before power off to ensure full saturation of power.

Avoid excessive charging and discharging: Try to avoid the battery being lower than 20% in daily use, and charge in time if there is a battery warning. Disconnect the power supply in time after it is fully charged, and do not keep the charging state for a long time to prevent overcharging from damaging the internal structure of the battery.

Daily cleaning and inspection

Appearance cleaning: Regularly wipe the surface of the battery with a dry soft cotton cloth to remove dust and oil stains. Stubborn stains can be diluted with a small amount of neutral detergent and wiped to avoid liquid infiltration into the interface after drying.

Parts inspection: Check whether the terminals are loose and oxidized every week. The oxide layer can be polished with fine sandpaper and coated with a small amount of anti-rust grease. At the same time, check whether the shell is bumped, deformed and leaked. If you find any abnormality, stop using it immediately and contact a professional.

Long-term storage and maintenance

Storage environment requirements: If the forklift is not used for a long time, the battery should be stored in a dry and ventilated place at 0-25 ° C with a humidity lower than 60%, away from direct sunlight and corrosive substances. After removal, it should be placed on a stable bracket to avoid extrusion.

Regular recharge: Recharge every 30 days during storage to maintain the power at 50% -70% to prevent power loss from causing performance degradation and affecting subsequent use.

exception handling

Common abnormal investigation: If the charging slows down or the battery life plummets, first check whether the charger is normal. After exclusion, you need to check whether the battery cells are attenuated. Contact a professional for evaluation, and do not disassemble it yourself.
