1. Durability: Lead acid batteries generally have a deep charge and discharge time of no more than 300 times, have memory, and a lifespan of about two years. Moreover, lead-acid batteries contain liquid. After a period of consumption, if the battery is found to be hot or the charging time becomes shorter, it is necessary to replenish the liquid. Lithium batteries have strong durability, slow consumption, and can be charged and discharged more than 500 times without memory, with a general lifespan of 4-5 years.

2. In terms of volume and quality: Generally, lead-acid batteries weigh 16-30 kilograms and have a relatively large volume. Lithium batteries generally weigh 2.5-3 kilograms and have a relatively small volume, making them lightweight and easy to transport.

3. In terms of price and warranty period: Currently, the mainstream battery on the market is 48 volts. If replaced, lead-acid batteries cost around 450 yuan with a warranty period of 1 year. Lithium batteries are relatively expensive and cost around 1000 yuan, but the warranty period is two years.

4. Driving kilometers: Both lead-acid and lithium-ion electric vehicles can travel 30-40 kilometers with the same 48 volt battery when fully charged. The speed mainly depends on the size of the motor used.

5. Battery capacity: The lead-acid battery has a capacity of about 20 amperes; The capacity of lithium batteries is 8-10 amperes.

6. Environmental protection: There is pollution in the production process of lead-acid batteries: improper recycling may also cause pollution; Lithium batteries are relatively green and environmentally friendly.

Most people will definitely be more concerned about the price and the most important component of an electric vehicle, the battery, before purchasing a car. There are only two types of batteries on the market: lead-acid batteries and lithium batteries, which greatly determine the overall price. Lead acid batteries are cheap while lithium batteries are expensive, which makes many consumers hesitate to choose lead-acid batteries.

At present, there are a variety of battery brands, styles, and brands selling electric vehicles, with lead-acid batteries and lithium batteries occupying the dominant position. Below, the editor will compare them to help you better understand the relationship and differences between these two.

In terms of battery capacity

The capacity of lithium batteries is generally 8-10 amperes, while the capacity of lead-acid batteries is around 20 amperes.

In terms of driving kilometers

For example, with the same 48V battery, both lithium-ion and lead-acid electric vehicles can travel 30-40 kilometers when fully charged, and their speed mainly depends on the size of the motor used.

In terms of durability

Lithium batteries have strong durability, slow consumption, can be charged and discharged more than 500 times, and have no memory, with a general lifespan of 4-5 years. Lead acid batteries generally have a memory and a lifespan of about two years, with deep charging and discharging up to 400 times. If using maintenance free lead-acid batteries, it should be noted that their battery has a low water loss, and distilled water is generally not needed during use. In terms of durability, lithium batteries have good vibration resistance. The fully charged battery is securely fixed and vibrates for 1 hour at a frequency of 16.7Hz with a 4mm amplitude. There is no leakage, expansion or rupture of the battery, and the open circuit voltage is normal; Good overcharging resistance, 25 degrees Celsius, fully charged battery with 0.1CA charge for 48 hours, no leakage, no battery expansion or rupture, normal open circuit voltage, capacity maintenance rate above 95%; Good resistance to high current, fully charged battery with 2CA discharge for 5 minutes or 10CA discharge for 5 seconds, no conductive parts melted, and no appearance deformation.

In terms of price and warranty period

The current mainstream battery in the market is 48 volts. If replacement is needed, lead-acid batteries cost around 380-450 yuan (48V12AH-48V20AH) with a warranty period of 1 year; Lithium batteries are relatively expensive, costing around 1000 (48V12AH) yuan, but their warranty period is 2 years.

There's something wrong with your question. A battery generally refers to lead-acid batteries, which are used as starting batteries for cars. Lithium batteries are lithium batteries, and your picture shows electric vehicles. So what you want to ask is how to distinguish the batteries of electric vehicles. If it's this issue, I can responsibly tell you that electric vehicles do not use lead-acid batteries. Nowadays, electric vehicles are divided into the lithium-ion camp represented by Tesla, and the lithium iron phosphate battery represented by BYD, which is not easily distinguishable. Except for Tesla, all other electric vehicles are lithium iron phosphate batteries.
