We’ve been selling batteries for about seven years now

First complaint about Sanyo 18650 grade B and C

We sold a lot of Sanyo 18650 batteries. There are eight grades of ABCDEFGH in the battery box. Maybe there are more I haven’t seen

At present, the quality gap of the eight grades I know is very small, and all grades can be used for battery packs

Battery of the same grade is recommended for battery pack

I don’t have any relevant documents at present

Sanyo’s quality is very good, and the defective products are directly discarded

Sanyo’s grade B is not the grade B in our industry

Generally, the quality of battery grade B is significantly different from that of Grade A

For example, the battery made in China has Grade A capacity of 3000mAh and Grade B capacity of 2900mah

I have tested Sanyo battery before, but the difference is hard to distinguish, and the testing instrument also has precision error.

Current test data lost

If you have relevant documents or measured data, please add

thank you very much

Wellp, looks like you aim to determine how can you identify the battery grade of a given shipment from Sanyo or sort of. I can't straight help much in that regard, but you can visit the lithium-ion batteries section in Panasonic Industrial site. There is a Contact Us tab which you can use to request them the information you need. Take your time to fill the contact form, they just went on vacation from April 29 to May 6 (Japan's Golden Week holidays).
