When the cold winter comes, many forklift operation and maintenance masters have discovered that the battery life of electric forklifts has "shrunk" seriously, and the charging capacity is still not enough? In fact, this is not a battery "strike", but the low temperature is causing trouble! The optimal operating temperature of lead-acid batteries is 25-30°C. At minus 10°C, the capacity may only be 50%. Share 4 core maintenance tips to help you stabilize battery performance~

 Charging environment: Keeping warm is the key

Never charge in the open air at low temperatures! It is recommended to park the forklift indoors or build an insulation shed to ensure that the charging environment temperature is 5-30°C. After putting the car away, charge it quickly while the battery is still warm, which can greatly improve the charging efficiency. After the red light on the charger turns green, float charge for another 1-2 hours to ensure that the battery is "full", but do not exceed 12 hours to avoid overcharging.

 Battery insulation: Refuse to "run naked"

Put on some "warm clothes" for the battery! Wrap the battery pack with special insulation material, focusing on covering the terminals and casing. Be sure to park indoors at night to avoid freezing the electrolyte overnight in the open air. In extremely cold areas in the north, a heating device can be installed in the battery compartment to maintain the basic operating temperature.

 Discharge skills: Avoid "power loss"

At low temperatures, the battery's ability to withstand power loss decreases. It should be charged when 30%-50% of the battery is left. Never use it until it is completely out of power. When working, try to drive at a constant speed to reduce sudden braking and heavy-load starts, and reduce instantaneous power consumption pressure. If it is not used for a short period of time, it should be recharged once a day to prevent sulfide crystallization.

 Long-term storage: "Sleep" when fully charged

If the forklift needs to be idle, fully charge it before storing it to avoid power loss that may cause the freezing point of the electrolyte to rise. The storage environment should be kept dry and ventilated at 5-45℃, and the battery should be recharged every 30 days. Regularly wipe off the dust on the battery surface, check whether the terminals are loose, and apply Vaseline to prevent corrosion.

The core of battery maintenance in winter is to "maintain temperature and prevent battery loss." Doing these things will not only restore battery life, but also extend battery life. Please pass on your skills to your operation and maintenance colleagues!
