First, preliminary preparation and safety regulations
Before replacing the original lithium iron phosphate battery that loses power, it is necessary to make comprehensive safety preparations and tool preparations. First, be sure to disconnect the main power switch of the electric ground cow to avoid the risk of electric shock during operation; at the same time wear insulating gloves, goggles and other protective equipment to prevent battery liquid splashing or tools from accidentally touching the electric wiring. For tools, prepare socket wrenches, insulating crowbars, cleaning cloths, etc. that are suitable for battery fixing bolts to ensure that the tools are free of rust and the insulation performance is intact. In addition, it is necessary to confirm that the model and capacity of the original lithium iron phosphate battery to be replaced are suitable for the forklift to avoid subsequent failures due to non-compliance with specifications.
Second, the old battery removal process
The first step is to remove the external protective cover of the battery compartment and find the fixing bracket of the battery; use a socket wrench to loosen the fixing bolts, and pay attention to keep the bolts and gaskets to avoid loss. The second step is to follow the principle of "negative first and then positive" during operation. First disconnect the negative electrode terminal with an insulating wrench, and then disconnect the positive electrode wiring to prevent the positive and negative electrodes from accidentally touching and causing a short circuit. After disconnecting the wiring, wipe the dust and slight corrosion on the surface of the terminal with a cleaning cloth so that the new battery can be installed in good contact later. The third step is to gently pry both sides of the old battery with the help of an insulating crowbar to smoothly remove the lithium iron phosphate battery that has lost power from the battery compartment. Avoid bumping the battery shell during the process to prevent the battery from being damaged and leaking liquid.
III. New battery installation operation
Put the new original lithium iron phosphate battery into the battery compartment smoothly, and adjust the position to make it fully fit with the installation card slot to ensure that the battery does not tilt or shake. Then install the fixing bracket and tighten the fixing bolts one by one. Pay attention to moderate strength to avoid deformation of the battery case due to excessive tightening. The wiring process follows the principle of "positive first and then negative". First connect the positive electrode terminal and tighten the fixing nut, and then connect the negative electrode terminal to ensure that the wiring is firm and not loose. Finally reset the protective cover of the battery compartment and tighten the fixing screws to complete the preliminary installation.
IV. Post-replacement inspection and daily maintenance
After the installation is completed, connect the total power supply of the forklift, test the basic functions such as starting, lifting, and walking of the forklift, and confirm that all operations are normal. Check whether there is any heating or loosening at the battery terminals, and whether there are traces of liquid leakage in the battery compartment. In daily use, it is recommended to check the battery power regularly to avoid long-term power loss storage; keep the battery compartment clean and dry to prevent dust and water accumulation from affecting the battery performance; carry out regular charge and discharge maintenance according to the original factory requirements to prolong the service life of lithium iron phosphate batteries.
