Difference between the two:

In addition to the hardness and fall-resistance of the lead-acid battery material, the price is relatively low, 18650 manufacture and it can be reverse repaired; however, due to the large volume but small capacity, the battery network has a short service life.

A lithium battery is small in size, light in weight, large in capacity, long in service life, and has good charge and discharge resistance, but it is expensive, non-recyclable, and dangerous.

Advantages of lead acid batteries:

1. hard: Lead acid boss China has always abided by the principle that "he is strong by himself, the wind strokes the mountains, he is horizontal, he is horizontal, the moon shines on the river". It is very good to support very much if you fall and beat, repair yourself a little, and then you can continue to learn how to use.

There are many reasons why lead acid batteries have long been the king of electric vehicle batteries. Its price is about a third of that of lithium-ion batteries.

You can go to an electric car shop to make up for the difference, to replace the old, to minimize the loss. For the user, it is not of much benefit.

The cons are:

As shown in Figure 1, the volume weight is large, but the capacity is relatively small.

Lead-acid batteries have a short life, and they are generally discharged 400 times during deep charging.

Lithium batteries have the following advantages:

1. Light weight, small size: lithium batteries with small results are 2u002F3 of lead-acid batteries and 1u002F3 of lead-acid batteries compared with lead-acid batteries with the same capacity on the market. Since lithium batteries have the same capacity as lead-acid batteries, the reduction in weight increases the battery life by about 10% in electric vehicles.

2. Longevity: Lithium-ion batteries are good for your health. They generally last about four years, 1.5 times as long as lead-acid batteries. In addition to charging and discharging more than 500 times, the battery has no memory and is highly earthquake-resistant.

Lithium batteries are charged for 48 hours at room temperature, and the capacity remains above 95%. They can also be quickly charged and discharged under the special charger.

The disadvantages of lithium batteries are as follows:

1, high price: lithium battery production enterprises have high costs, production technology and equipment are expensive, and labor management costs can account for around 40% of production time's cost. The price is about three times as much as lead-acid batteries, but in spite of the three-fold price difference, it does not seem excessive, giving people a sense of opulence.

The lithium-ion battery cannot be recycled, and can only be thrown away when worn out, or buried, and thousands of years later, its descendants become antiques.

Safety risks: One of the main concerns with lithium batteries is the risk of fire and explosion, especially when consumers are unwittingly misled by profiteers, resulting in inferior lithium batteries being purchased. The sealing condition in electric vehicles is not very good, and it is easy for them to be damp, which may lead to poor contact, which may be dangerous.

In short, lead-acid batteries and lithium-ion batteries have advantages and disadvantages. Choose a regular battery manufacturer if you want to install a high-quality battery for your car, whether it is a lithium-ion battery or a lead-acid battery.
