New Fujitsu "Ready To Use" NiMH Batteries

In 2009 and 2010 Panasonic acquired Sanyo Electric. Since then they have been gradually making changes to the Sanyo line of products. After the acquisition, manufacturing of Sanyo's NiHM batteries (3rd generation) was moved to the FDK factory (owned by Fujitsu) in Japan. See this Fujitsu FDK site for details on their NiMH batteries and chargers. FDK claim to be the world's leading manufacturer of NiMH batteries! From their web site:At a 2010 survey, FDK had No.1 market share (27%) not only in Japan but also all over the world!

These batteries have similar specifications, and seem to be nearly identical. Just google "Sanyo Eneloop manufactured by FDK"! Due to legal reasons we can not make any assumptions in this article. But, after doing some research, it seems like these batteries are VERY similar. See below for information taken from external sites. This article is for information only!

From the FDK web site:FDK TWICELL Co., Ltd. is the only company to manufacture Ni-MH batteries exclusively in Japan and leads the industry with our unique technology and productivity.

The following batteries have similar (seem to be identical) specifications, and seem to be manufactured in the same factory in Japan:



Article at Master Instruments Australia stating that Sanyo NiHM acquired by FDK

The following is from this and this article published on the Master Instruments' site. It clearly states that there is only one producer of NiMH batteries in Japan, and they manufacture both Sanyo Eneloop and Fujitsu FDK batteries!

"Whether labelled as FDK(subsidiary of Fujitsu) or Sanyo. It is the same product from the same factory with identical specifications. Some product data sheets may still be under the Sanyo brand. Specifications & product data sheets under the FDK brand will become available as they're progressively produced. Please click the link below for individual product information & data sheets.

Article stating that FDK (Fujitsu) acquired Sanyo Eneloop batteries,

The following is from this article published on the federal trade commision site:"Major consumer electronics manufacturers Panasonic Corporation and Sanyo Electric Co., Ltd. have agreed to sell assets related to Sanyo’s portable nickel metal hydride (NiMH) battery business, including a premier manufacturing plant in Japan, as part of an agreement with the Federal Trade Commission that will preserve competition and allow the companies to proceed with Panasonic’s proposed $9 billion acquisition of Sanyo. NiMH batteries power two-way radios, among other products, which are used by police and fire departments nationwide.


Under a proposed FTC consent order, the portable NiMH battery assets will be sold to FDK Corporation, a subsidiary of FujitsuLtd. The sale of the assets resolves competitive concerns that were raised by the transaction, which combines the world’s two largest manufacturers and sellers of these batteries. No competitive concerns were raised by other overlaps between the companies."
