Why “PANASONIC” Is Not Written on the Battery

Many genuine NCR18650GA cells manufactured in China do not carry the “Panasonic” brand name printed on the outer wrapper. This is normal and intentional, not an indication of a fake product.

1. OEM / Industrial Supply
   These cells are often produced for OEM and industrial customers, where branding on the wrapper is unnecessary or omitted.
