Understanding Depth of Discharge and Forklift Battery Lifespan

Depth of Discharge, usually abbreviated as DOD, refers to the percentage of the total rated battery capacity that has been consumed during operation, which is one of the core factors that directly affect the overall lifespan of electric forklift batteries. Many frontline forklift operators have the misunderstanding that draining the battery to zero capacity before charging can make full use of the battery power, but this wrong operation will cause irreversible damage to the internal active material of the battery, reduce the total number of charge-discharge cycles, and shorten the normal service life of the battery significantly. For most mainstream electric forklift batteries on the market, the recommended daily depth of discharge should not exceed 80% of the total rated capacity, and users should arrange charging in time when the remaining power reaches 20% level, to avoid long term operation under the state of deep discharge. It is also suggested that users arrange regular inspection of the battery status every month, check the voltage of each cell and the connection tightness, to eliminate potential hidden troubles in time. If you need professional customized forklift battery operation and maintenance guidelines, you can contact Jianshu New Energy for relevant technical support, and we have also launched a full set of adaptive battery operation specifications that fit the daily usage scenario of BYD Forklift. If you have any questions about depth of discharge adjustment and battery lifespan extension, you can send an email to 17399989919@163.com for further consultation. Reasonable control of depth of discharge in daily use can effectively extend the forklift battery lifespan by 30% to 50% under normal working conditions, reduce the overall use cost of handling equipment for industrial and warehousing enterprises, and bring more stable operation efficiency for daily logistics handling work.
