The number of charge-discharge cycles of lithium-ion batteries can generally reach about 500-1000 times; some high-quality lithium-ion batteries can even achieve 1000-1200 charge-discharge cycles, with a service life typically ranging from 3 to 5 years. Currently, mainstream electric vehicles adopt lithium-ion batteries (such as ternary lithium batteries and lithium iron phosphate batteries). Compared with traditional lead-acid batteries, they have higher energy density (200-300 Wh/kg), longer lifespan (1000-2000 charge-discharge cycles), and lighter weight (only 1/3 of that of lead-acid batteries).

  The number of charge-discharge cycles of lead-acid batteries is usually around 300-500 times. Specifically, low-grade lead-acid batteries have about 300-400 charge-discharge cycles and a service life of approximately 1.5 years; mid-grade graphene lead-acid batteries have around 500-600 charge-discharge cycles and a service life of 2-3 years; high-grade lead-acid batteries have about 1000 charge-discharge cycles, and it is feasible for them to be used for 3-4 years.

• Usage Environment: Lithium-ion batteries have more stable performance and are less affected by temperature. They can work normally within a relatively wide temperature range, and their charge-discharge efficiency and lifespan remain relatively stable in both high and low temperature environments.Lead-acid batteries, however, are prone to electrolyte evaporation and loss in high-temperature environments, which shortens their lifespan. In low-temperature environments, the rate of chemical reactions in lead-acid batteries slows down, resulting in reduced charge-discharge efficiency and a significant decrease in driving range. Long-term use in low-temperature environments will accelerate the aging of lead-acid batteries.
• Usage Habits: To maintain optimal performance, lithium-ion batteries need to be recharged after the power is exhausted. When not in use for a long time, they should be fully charged every two months.For lead-acid batteries, over-discharging and over-charging should be avoided. It is advisable to start charging when the remaining power is about 20%-30%, and the charging time should not exceed 8 hours.
