18650 battery 3.7v 2000mah

　　What are the differences between 18650 battery 3.7v 2000mah and lead-acid batteries?

　　1. Comparison of safety factors: Different materials of power 18650 battery 3.7v 2000mah (lithium manganese oxide batteries and lithium iron phosphate batteries) have different safety factors. Lead-acid batteries have relatively mature technology and are safer than 18650 battery 3.7v 2000mah.

　　2. Environmental protection is relatively good. 18650 battery 3.7v 2000mah have zero pollution, while lead-acid batteries have excessive heavy metal lead pollution. Therefore, battery vehicles using lead-acid batteries will still cause pollution to the environment.

　　3. Price comparison: The price of 18650 battery 3.7v 2000mah of the same capacity on the market is more than twice as expensive as lead-acid batteries. That's why pure electric vehicles using 18650 battery 3.7v 2000mah are more expensive.

　　4. Comparison of kinetic energy. The mass ratio, volume and kinetic energy ratio of 18650 battery 3.7v 2000mah are about 40% higher than that of lead-acid batteries.

　　5. The lifespan of 18650 battery 3.7v 2000mah is relatively low. The lifespan of 18650 battery 3.7v 2000mah per month does not exceed 3%, and that of lead-acid batteries is 15~30%. There is a big gap between the two.

　　6. The service life is relatively long. At present, lithium iron phosphate batteries generally have no memory after being charged 1500 times, and the storage capacity is about 85% after 1500 times. However, lead-acid batteries have a large storage capacity after about 500 times. The amplitude is reduced and the memory is significant. Therefore, the battery cycle times of battery vehicles using 18650 battery 3.7v 2000mah will be longer.

　　7. The working voltage platform is relatively high. The working voltage platform of 18650 battery 3.7v 2000mah is more than 3V, and that of lead-acid batteries is 2V.

　　8. The charging and discharging characteristics are relatively different. Simply put, 18650 battery 3.7v 2000mah can charge and discharge about 30% more than lead-acid batteries when charging and discharging at large currents.

　　9. Durability, lithium battery durability and impact resistance. Rechargeable batteries are safe, have low power consumption, can be charged more than 500 times, have no memory, and generally have a service life of 4-5 years. Lead-acid batteries generally have less than 400 charges and a long service life of about 2 years. If maintenance-free lead-acid batteries are used, it should be noted that rechargeable batteries lack water and purified water is generally not used during use.
