How to distinguish lithium battery and lead battery of electric vehicle?

When you have an electric car, how do you tell if the battery of this electric car is a lead battery or a lithium battery?

1, durability: lead-acid batteries generally deep charge deep discharge within 300 times, there is memory, life expectancy is about two years. In addition, there is liquid in the lead-acid battery. After a period of consumption, if the battery found to be hot or the charging time is short, the liquid needs to replenish. The lithium battery has strong durability, slow consumption, more than 500 times of charging and discharging, and no memory. Life expectancy is 4-5 years.

2, volume, quality: the general lead-acid battery weight is 16-30 kg, a large volume. Lithium batteries are generally 2.5-3 kg, and the volume is relatively small, so the ride is light and convenient to carry.

3, the price, warranty period: the current mainstream battery on the market is 48 volts, if replaced, lead-acid battery 450 yuan or so, the warranty period is 1 year. Lithium batteries are relatively expensive and cost around 1,000 yuan, but the warranty period is two years.

4, driving kilometers: the same 48-volt battery, in the case of full charge, lead-acid batteries and lithium battery electric vehicles can travel 30-40 km. The speed depends mainly on the size of the motor used.

5. Battery capacity: The capacity of lead-acid battery is about 20 amps; the capacity of lithium battery is 8-10 amps.

6. Environmental protection: There is pollution in production process of lead-acid batteries: if it is improperly recycled, it may cause pollution; lithium batteries are environment green.
