Be careful not to buy electric car refurbished battery

Yesterday, the citizen Mr. Zhang called the newspaper to report: More than two months ago, he exchanged an electric vehicle battery through the old-for-new way. Recently, he found that the battery storage capacity has dropped significantly. After testing, the battery was refurbished. The life expectancy is only about half a year. Industry insiders remind consumers: if the newly purchased electric vehicle battery has a reduced storage capacity after 2 months of use, the battery may be a refurbished battery.

Repair shop is selling refurbished batteries

Yesterday, the reporter visited a number of electric vehicle repair shops and found that these stores have acquired old batteries or batteries for trade-in business.

In an electric vehicle repair shop near the Qilihe Bridge, the store owner told the reporter: When replacing the old battery with a new battery, the battery with a storage capacity of 80% or more can be reduced to 100 Yuan, and the battery with a storage capacity of 50% or less can be offset 40 Yuan to 50 Yuan.

The owner of another electric car repair shop said that the new battery sold for 400 Yuan, the old battery can be reduced to 150 Yuan. The repair shop staff said that the way to renovate the old battery is simple: after opening the battery, refill the chemical acid required for the battery and repackage it.

"There are mostly refurbished old batteries sold in the store, otherwise how could it be so cheap?" The above staff said that the price of a brand new battery is about 600 Yuan, and the price of refurbished batteries is about 200 Yuan. "The profit of recycling and renovating old batteries can be much more profit than repairing a car. The life of a new battery is about 2 years. Nowadays, so many people on the street are riding electric cars, and the business of replacing the battery with the old one is naturally very good.”

There are ways to identify refurbished batteries

Mr. Sun, a staff member of a brand electric vehicle after-sales service point, said that due to limited processing capacity, the old batteries of some small workshops have a very short service life, which may be only about half a year, "although new batteries are sold than the brand electric vehicles." It's cheap, but using this battery is actually not cost-effective."

Mr. Sun said that when people buy batteries, they must first look at whether the outer packaging of the battery is intact. Pay special attention to the instructions on the outer packaging. It should be noted that many manufacturers make strict distinctions between the batteries for new electric vehicles and the new batteries required for customer replacement. Some brands will mark the words “not for sale” or “maintenance” on the battery packaging sold at the after-sales service.

The date of manufacture indicated on the battery also has a reference role. If the date of manufacture is more than 2 months from the date of purchase by the consumer, it is not recommended to purchase the battery: after the battery is left for a long time, the capacity will decrease and the service life will be shortened.

In addition, the old battery will look rough on the surface anyway. The surface of the new battery is electroplated and smooth; the pole of the refurbished battery is polished and rough.
