Recharging the battery is inevitable. Therefore, the only way to keep the forklift running is to replace the low-power battery in time, and put the low-power battery back to the original place for charging. In the past, one way to replace the forklift battery was to do it manually or through some kind of lifting equipment. Or another method is to manually pull the battery out of the forklift, and then manually push the replaced battery back in. Of course, these two processes are done under ideal conditions, but there are always some security risks associated with dealing with large projects. For example, during the battery drop may cause the battery fluid to leak out, if so the battery fluid may cause some damage to the battery, the floor and some equipment.

Overall improvements to forklift and battery design by Oems and battery manufacturers have made it possible to replace batteries without any manual operation. At present, the battery elements of most forklifts are already connected to the drum battery chamber on the ground, so that the charging facility and the forklift battery are at the same height. The forklift driver only needs to open the forklift to the charging position, and exchange the position of the low-power battery and the full battery through the way of the roller to complete a battery replacement. For those heavy or larger batteries on large vehicles, forklift mechanical assistance can be done, such as moving the battery to a set position through a magnetic arm.
