Panasonic Batteries
Panasonic is one of the brands the company states it distributes, alongside Duracell, Maxell, and B.B. Battery. The image above shows the four brand marks the company displays on its site. Those marks are third-party trademarks, not Unitek's own brand, and this page does not present them as such.
Every Panasonic specification on this site is Panasonic catalog data, carried on the distributor's brand page. The CR, BR, VL, ML, cylindrical, 18650, 21700, 22700, NiMH, and dry-cell tables on their own pages all carry that attribution, and none of them is presented as a cell manufactured by Unitek.
The company's site uses more than one wording for its Panasonic relationship, covering partner, pack-factory, test-lab, and distributor wordings. The scope of each wording is not separately confirmed, so this site does not merge them into a single claim and does not present any one of them as independently verified.
Ask for the datasheet of a named Panasonic model before ordering, and confirm the exact model, the variant, and the ordering steps for that model.
What to confirm before ordering
Which family fits the question? Which listed name, if any, is in question? What documentation is available on request? What are the ordering steps for the named item?
