1. Durability/Battery Life: Lead-acid batteries generally have a lifespan of about 2 years, while lithium batteries are more durable and have a lifespan of 4-5 years. Lead-acid batteries can generally be fully charged and discharged within 300 cycles, while lithium batteries can be fully charged and discharged more than 500 times.
2. Size and weight/ease of operation: Compared to the lightweight body of a lithium battery vehicle, which weighs only 2.5/3 kg, a lead-acid battery of the same capacity typically weighs about 16/30 kg; not only is the battery heavier, but the size is also larger; compared to the laborious maneuvering of lead-acid vehicles, lithium battery vehicles have a detachable design, making them more convenient to ride and transport.
3. Market Price/Value for Money: Currently, the mainstream lead-acid battery on the market costs around 450 yuan, while lithium batteries are more expensive, costing around 1000 yuan. The price difference between the two types of batteries leads to a significant difference in the price of the corresponding electric vehicles. Furthermore, lithium batteries have a warranty period that is one year longer than lead-acid batteries, offering a two-year warranty.
4. Driving Range/Battery Capacity: With the same 48V battery, lead-acid and lithium-ion battery electric vehicles have roughly the same driving range when fully charged. The specific range depends on factors such as speed and motor size. However, lead-acid batteries generally have a slightly larger battery capacity than lithium-ion batteries.
5. Mileage: With the same 48V battery, both lead-acid and lithium battery electric vehicles can travel 30-40 kilometers on a full charge. Speed mainly depends on the size of the motor used.
6. Price and warranty period: The mainstream battery on the market is 48V. If you want to replace it, the lead-acid battery costs about 450 yuan and has a warranty period of 1 year. The lithium battery is relatively more expensive, costing about 1,000 yuan, but has a warranty period of 2 years.
7. Environmental protection: After the State issued the "Access Conditions for the Lead-acid Battery Industry" in 2012, the lead-acid battery industry underwent restructuring and integration. Most manufacturers have adopted internalized cadmium-free and arsenic-free green production, which is more environmentally friendly and energy-saving. However, if the recycling process is not handled properly, it may cause pollution. Lithium batteries are relatively greener and more environmentally friendly in terms of production and recycling.
8. Trends: With the introduction of new national standards for electric bicycles, lightweight and high-energy-density batteries have become an inevitable trend in power energy. Lithium batteries are undoubtedly the best choice and the development trend.
Having seen the eight differences above, you'll likely find that lithium battery electric vehicles seem to have more advantages compared to lead-acid batteries, which are difficult to operate, bulky, and not durable. Of course, lead-acid battery electric vehicles are cheaper.
Compared to lead-acid batteries, lithium batteries have a higher average voltage and higher energy density; in other words, for the same battery size, lithium batteries have a greater capacity. Additionally, lithium batteries are relatively lightweight and portable, and have a much longer lifespan. Furthermore, lithium batteries are more adaptable to high and low temperatures, less affected by temperature factors, and are more environmentally friendly.
Of course, lithium batteries also have three drawbacks. If inferior batteries are chosen, their safety and stability are relatively poor, and improper handling can easily lead to spontaneous combustion. However, if a reliable product is chosen, the possibility of spontaneous combustion is extremely low. Additionally, lithium batteries cannot discharge at high currents and have stringent production requirements, resulting in higher costs. In contrast, lead-acid batteries are relatively cheaper and more readily accepted by the public. Furthermore, lead-acid batteries have better high-rate discharge performance. Most importantly, lead-acid batteries fetch a higher recycling price than lithium batteries.
However, lead-acid batteries also have their own disadvantages, such as heavy metals causing environmental pollution; compared with lithium batteries, lead-acid batteries have lower energy density; and their lifespan is shorter than that of lithium batteries.
