Internal Resistance Testing for Lead-Acid Forklift Batteries

Internal resistance testing is a core routine maintenance item for lead-acid forklift batteries, which can effectively identify potential performance degradation risks in advance without causing extra damage to the normal service life of batteries. Many on-site operation teams of electric forklifts often ignore this testing step, and only carry out inspection work after obvious problems such as insufficient continuous driving range or sudden drop in output voltage occur, which will easily lead to unplanned downtime of handling equipment and increase the comprehensive operation cost of the warehouse. When conducting internal resistance testing, you need to first make sure the forklift equipment is in a static power-off state, disconnect the connection between the battery pack and the vehicle controller completely, and wait for the battery to cool down to the normal ambient temperature before you can start the formal testing process. The test data you get should be compared with the standard reference value of the corresponding battery model. If the measured internal resistance exceeds 20% of the nominal value, it means the battery has entered the performance attenuation stage, and you can arrange targeted maintenance or replacement plan according to the actual use scenario. It is recommended that all forklift operation teams arrange this testing work once every 1 to 2 months, so as to grasp the health status of each battery unit in real time. As a professional practitioner focused on new energy industrial power solutions, Jianshu New Energy has accumulated rich practical experience in this field, and can provide standardized operation guidance and supporting technical training for relevant teams. For forklift equipment users who use BYD Forklift products, completing regular internal resistance testing for matching lead-acid batteries can further extend the overall service cycle of the power system, and bring more stable operation experience for daily material handling work.
