The national approved service life of battery for electric vehicles is 2-3 years, while most users of electric vehicles use less than one year. There are two main reasons for this: one is the failure to purchase regular brand batteries; the other is the failure to pay attention to battery maintenance when using them. Today I'll give you some tips on how to buy batteries for electric cars.
I. Looking at the Appearance
When purchasing, it has a good reference for judging whether the battery appearance of the electric vehicle is good or bad. It can avoid the situation of sub-charge and non-national standard batteries. What details should we pay attention to?
1. Look at the battery label. Battery label is affixed to the seal of battery cover plate and battery shell to see if it is open, damaged, and altered. Do not buy if the above phenomenon occurs. Also pay attention to whether there are anti-counterfeiting authentication codes, we must check the authenticity.
2. Look at the battery case. There will be no scratches, deformations, cracks, leaks and other phenomena in the battery shell of the new electric vehicle. See if the shell specifies the production address, production license number, specifications and production date.
3. Look at the battery capacity. The nominal battery capacity of EV is related to the range of EV and battery price. The smaller the nominal capacity, the lower the battery price, and the shorter the range of the electric vehicle. We must choose the batteries matching the electric vehicle, and do not arbitrarily change the standard of the electric vehicle.
Electric vehicle batteries are divided into national standard batteries and non-standard batteries. The weight and price of non-standard batteries are quite different from those of national standard batteries.

When purchasing batteries for electric vehicles, we must pay attention to the above details. I hope these purchasing techniques can help you choose the right batteries for electric vehicles.
