Why are used lead-acid batteries so popular?Lead battery recycling plant

Some people earn millions RMB yearly by recycling of used electric bike battery, lead-acid battery is the most popular for electric bike battery recycling. Now there are two categories of electric bike battery, they are lead-acid battery and lithium battery, among which lead-acid battery occupies 80% market share in the electric bike battery market, followed by new energy lithium battery.

The reasons that used lead acid battery recycling become hot

Lead-acid batteries play a dominant role in the electric bike battery market because of their low price and high recycling price, which can be exchanged for new ones. Riding electric bikes are  wage earners, their income is limited, lead-acid battery safety has a good reputation. Lead-acid batteries do not explode even if they are packed and several batteries stick together due to high temperature. Safe replacement and low price are the main reason for the popularity of lead-acid batteries. High market share and complete recycling industry chain are the main reasons for the popularity of used lead-acid battery recycling.

Trading-in old batteries for new ones is the first stop where old batteriess appear

Our new electric bike will need to be replaced when the lead acid battery declines after two or three years of use. All electric bike repair shops will launch the business of trading-in old batteries for new ones, repair master can earn a little difference (30~50 Yuan profit) from changing a group of new battery, the old battery which has replaced will be accumulated and specific personnels will be notified to collect and recycle, and they can earn the difference profit from this, this is the main source of income for electric bike repair shop.

Value of lead-acid batteries

The most valuable of used lead-acid batteries are the lead, nickel, aluminum and other rare metals that can be recycled. The waste plastic casings from lead-acid batteries can also be recycled. The lead, nickel, aluminum and recycled plastics which are refined from the lead acid batteries can be made into new lead acid batteries that can be put on the market for further use.

Sometimes new raw material price increases, which makes the high cost of electric bike battery manufacturers, while the price of lead, nickel and lead which are refined from used batteries are more preferential, there is no difference on the use for regeneration metals and new refining metal, just price is more preferential, sometimes it will cause the shortage of refined metal. As a result, used batteries are in high demand.

The reason why old batteries are popular is that old batteries can be replaced with new ones, and old electric bikes can also be replaced with new ones.

Most of the electric bikes we use are 48V, 60V and 72V. For these 4~6 batteries, it is generally unlikely that every battery will fail. When electric bike repair master replace electric bike battery for customers, they will use multimeter to measure a group of battery (which has been replaced) after battery discharge, if the voltage after discharge is higher than 12.5V it can continue to be used, the battery less than 12V should be scrapped.

Electric bike repair master will store these old batteries (which still could be used) together after sufficient charging. When some customers appear the problem of shorter endurance mileage, as long as the customer agreed to repair the battery, the battery master will remove and measure this group of battery, if there is 1~2pcs battery in the same group is bad, but other pieces of battery in the same group is good, then it can continue to be used, and the repairman will offer the old change old service for customer.

In this way, the used batteries can be recycled, reducing pollution, saving money for customers and creating profits for repairmen. At the same time, the price of a replacement battery is the same, which is one of the reasons why the old battery is so popular.

The value of dismantling and recycling of used lead-acid batteries

Waste lead-acid batteries contain 74% lead plates, 20% sulphuric acid and 6% plastic. According to the current technology in our country, the reuse rate of a group of lead batteries can reach 80%, and some enterprises with more advanced equipment can even reach 98%.
