Forklifts are widely used in warehouse logistics, manufacturing material handling and other industrial scenarios, and the power battery is the core component that supports the continuous and stable operation of electric forklifts. After thousands of cycles of daily charging and discharging, individual cells inside the battery pack may show performance attenuation such as capacity drop, internal resistance rise, which will affect the overall performance of the whole battery pack. Conducting standardized forklift battery cell replacement in time is an effective measure to avoid potential safety hazards, reduce operation cost and extend the service life of electric forklifts.

The first essential step before carrying out cell replacement is to complete full safety assessment. Operators must cut off all external power connection of the battery pack in advance, wear insulated protective gloves, goggles and corresponding anti-static work clothes. The operation area should be kept ventilated, no open flame or flammable and explosive items are allowed to place within 3 meters around. Operators need to test the residual voltage of the battery pack, and check for abnormal swelling, liquid leakage or scorch marks on the surface of the battery shell, to confirm there is no risk of thermal runaway before formal disassembly.

The second core essential point is to ensure the matching consistency of new replacement cells. All new selected cells must keep fully consistent with the original battery pack in terms of nominal voltage, rated capacity, maximum charge and discharge rate, internal resistance range and size specification. Any mismatch of core parameters will lead to unbalanced operation of the whole battery pack, accelerate the attenuation speed of other normal cells, and even cause abnormal heating, protection trigger and other abnormal conditions in subsequent use.

The third key point is to standardize the whole replacement operation and post-commissioning process. When disassembling the old faulty cells, operators should avoid pulling the harness and sampling lines with excessive force, mark the sequence of each connection point in advance, and paste high-performance insulating isolation pads on all exposed metal connection points after the new cells are in place. After the replacement is completed, full equalization calibration for the whole battery pack is required, and 2 to 3 hours of simulated load charge and discharge test should be carried out, to confirm all operation parameters are within the normal range before the battery pack is put back into use.
