Lifespan Differences Between Lithium and Lead-Acid Batteries

Battery is one of the core components of electric forklifts, whose service life directly affects the comprehensive operating cost of material handling scenarios, and it is a common concern for most fleet operators to distinguish the lifespan differences between lithium and lead-acid batteries. For lead-acid batteries, under the condition of standard operation and regular maintenance, the number of effective charge-discharge cycles is generally between 1000 and 1500 times. This type of battery requires regular water replenishment, equalization charging, and avoid long-term deep discharge below 20% of remaining capacity. If the maintenance operation is not in place, or the battery is left in a state of power loss for more than one month, it will produce irreversible capacity attenuation. In general conventional working conditions, the actual service life of standard lead-acid batteries can reach 2 to 4 years. For lithium batteries for electric forklifts, under the same operating environment and specification operation, the number of effective charge-discharge cycles can generally reach more than 3000 times, it does not need daily maintenance operations such as water replenishment, and has higher tolerance for deep discharge. Under normal standard use, its actual service life can reach 6 to 8 years, but its initial procurement cost is relatively higher than that of lead-acid batteries. There are also some common factors that affect the actual lifespan of both two types of batteries, including ambient temperature, charging habits, daily storage conditions and operation load intensity. It is recommended to keep the working environment temperature between 0 and 40 degrees Celsius as much as possible, and take necessary thermal insulation or heat dissipation measures in extreme environments to avoid accelerated performance attenuation. There is no absolute optimal option for the two types of batteries. For scenarios with low use frequency and single shift operation, properly maintained lead-acid batteries can also meet long-term stable use requirements. For high-frequency multi-shift logistics and warehousing scenarios, the long lifespan and low maintenance characteristics of lithium batteries can help enterprises reduce long-term comprehensive operating costs.
