What Are the Advantages of Comparing Forklift Lithium Batteries with Lead-acid Batteries?

Forklift lithium batteries charge faster than forklift lead-acid batteries


Lithium batteries satisfy the requirement for faster charging due to their chemical properties. They can be charged from 10% to 100% in just 2 hours, while lead-acid batteries take 8-10 hours to charge from 20% to 100%.


Forklift lithium batteries have no memory effect


The no-memory characteristic of forklift lithium batteries allows for random and intermittent charging without affecting the battery's lifespan. Operators can efficiently utilize their work and rest time to supplement the battery's power, making it more convenient to coordinate operations. During the charging and discharging process, lithium batteries lose less energy and always maintain extra output power regardless of the remaining battery level.


Lead-acid batteries have memory effect, which can seriously damage the battery and shorten its lifespan during random or intermittent charging. Correct charging and discharging operations for lead-acid batteries include charging and discharging from 20% to 100%, and regularly balancing the charging. This makes it inconvenient for operators to coordinate their operations.


Forklift lithium batteries have a longer lifespan


The average cycle life of lead-acid batteries is 1200 times (operating time is about 6000 hours), while lithium iron phosphate batteries have more than 4000 cycles (operating time is about 24000 hours). In practical use, after more than 4000 cycles, lithium iron phosphate batteries still have more than 65% of their capacity, while lead-acid batteries lack 50% of their capacity after 1200 cycles.


Forklift lithium batteries have a wider discharge temperature range than forklift lead-acid batteries


Under high or low temperature conditions between -20℃ and 60℃, lithium batteries have excellent discharge performance. At -20℃, the discharge power of forklift lithium batteries is 80% to 90%, while lead-acid batteries lack 30% of their discharge power.


Forklift lithium batteries increase operational power


The fast charging of lithium batteries, which takes 1-3 hours, is suitable for multi-shift operations. The immediate use of the battery without the need for replacement saves time and reduces safety risks. The power is also stronger, making it possible to replace internal combustion forklifts. Technical monitoring of forklifts and battery conditions improves forklift management level.


Compared to lead-acid batteries, lithium batteries can also be formulated to produce various special functions, providing various power supports for the innovation planning of forklifts. For example, low-temperature lithium batteries can provide functionalities that lead-acid batteries cannot.


Because forklift lithium batteries have unparalleled advantages compared to traditional lead-acid batteries, their use in the forklift industry will have a strong impact on the existing forklift market structure. The emergence of lithium battery forklifts is a trend, as the rapid development of the logistics industry requires a forklift with short charging time, long operating time, stable functionality, capable of withstanding high-intensity operations, and having high levels of automation and intelligence.
