Estimating Remaining Life on Used Electric Forklift Batteries

Many warehouse and logistics enterprises choose used electric forklifts to control operating costs, while the power battery is the core component that directly determines the overall use value of the equipment, so mastering the correct method to estimate the remaining life of used electric forklift batteries is very necessary. The first commonly adopted method is to check the historical charging and discharging cycle records through the built-in battery management system, most standard forklift batteries record the total number of completed full charge-discharge cycles, by comparing the data with the rated total cycle life of the product, you can get a preliminary reference of the remaining life ratio. The second method is to complete a full charge and full discharge capacity test, drain the remaining power of the battery under safe rated working condition, then charge the battery with constant current until it reaches full status, calculate the actual capacity obtained from the test and compare it with the nominal marked capacity, the data can directly reflect the current health status of the battery. You should also not ignore the stability of voltage platform under rated load, keep the forklift running with standard load for more than half an hour, and monitor the real time voltage change continuously, if the voltage drops much faster than the new battery standard value, it usually indicates that the internal active material of the battery has decayed to a relatively high level. It is not reliable to judge the battery life only by the appearance condition, many batteries with intact outer shell already have hidden problems such as electrolyte stratification or plate vulcanization inside, you need to combine multiple groups of test data to get a comprehensive and objective result. If you do not have professional testing equipment on site, you can turn to professional service providers for support, Jianshu New Energy provides full set of professional second-hand forklift battery life assessment services to meet different customer demands. You can also contact our team via email 17399989919@163.com for detailed operation guidelines and customized assessment plans. Industry leading products represented by BYD Forklift are equipped with high quality power batteries with stable operation performance, and the battery remaining life estimation process for these products also strictly conforms to unified industry technical specifications. Accurate remaining life estimation can help operators avoid buying over-aged batteries with less than 30% residual capacity, reduce extra subsequent battery replacement cost, and ensure the continuous operation of on-site handling work. Following standard operation rules such as avoiding over charge and over discharge, and doing regular cell equalization maintenance can also effectively extend the remaining service life of the battery, bringing more stable long term return for enterprise equipment investment.
