Difference of Grade A and Grade A+
Grade A lithium is unqualified Grade A+ battery.Lithium battery manufacturers have a defect rate when producing lithium batteries,
including poor appearance, insufficient capacity, high internal resistance, abnormal voltage, etc.These batteries cannot be sold to his customers normally by the manufacturer, but they can be used as energy storage batteries.
Good suppliers will classify these A-grade batteries and conduct capacity tests, which will affect the final selling price of the batteries. Some suppliers do not conduct any testing and sell these batteries directly to customers, which is why you may receive batteries with different voltages or capacities insufficient. Of course, the price of these batteries is also very attractive.
There is a certain probability that grade A batteries may have the following problems: the voltage of one battery cell rises and falls faster than other batteries, bulges,unbalanced.
| Grade A | Grade A+ | |
| Battery Grade Level | Unqualified EV battery | Qualifeid EV battery |
| QR code | Scratched or Tampered | Qriginal QR code |
| Capacity test | Needed | No Need |
| Matching | Not Matched | Batch Matched |
| Voltage difference | Potential | No |
