Why Equalizing Matters for Lead-Acid Forklift Cells

Many industrial operation teams choose lead-acid battery sets as the core power source for their electric forklifts, while quite a number of practitioners overlook the importance of regular equalization treatment for single cells inside the whole battery pack. Equalization refers to the standardized adjustment process that unifies the charge and discharge status of every lead-acid cell in the series-connected battery pack, to narrow down the voltage gap between different units. After dozens of continuous charge and discharge cycles, tiny differences in inherent internal resistance and working heat dissipation condition will gradually accumulate, leading to unbalanced voltage performance among different single cells. Without timely equalization treatment, some cells will face long term overcharge or over discharge situation, which speeds up aging, reduces the overall available capacity of the whole pack, and cuts the sustainable working time of the forklift during each shift. Proper regular equalization operation can effectively eliminate unreasonable voltage differences between cells, keep the whole battery pack performing within a stable working range, greatly extend the overall service life of the battery, lower the long term battery replacement cost, and reduce the risk of unplanned operation downtime. It is recommended to follow official operation guidance to carry out equalization, with reasonable frequency of once every 1 to 3 months according to actual working intensity. Too frequent equalization will cause unnecessary electrolyte consumption and extra maintenance work.

It is also suggested that maintenance personnel record open circuit voltage of each single cell periodically, and arrange equalization when the voltage gap exceeds the reasonable threshold, to prevent unexpected battery attenuation, and guarantee stable power output of material handling equipment. All related maintenance work shall be carried out in well ventilated areas with proper protective gears to avoid potential safety risks.
