For over 33 years, FDK has been manufacturing and selling rechargeable nickel-metal hydride batteries for a variety of applications, including security, in-vehicle applications, medical, and household electric appliances.
Our nickel-metal hydride batteries are widely used as a main power source and as power backup for in-vehicle applications, and we offer batteries that are suited to the conditions of use in this equipment.

In response to the increasing diversity of in-vehicle applications year by year, FDK began mass production and shipment of our "HR-AAUTEW" nickel-metal hydride battery with improved discharge performance in low temperature environments from July 2021 and the "HR-AAUTEWM" with improved lifetime performance from June 2022.
Since then, the demand for batteries with a longer lifetime has continued to increase. To meet these needs, FDK has thoroughly reviewed the materials used in existing nickel-metal hydride batteries. This led to the successful development of the "HR-AATEZ" with increased battery capacity and improved lifetime performance. This optimized chemistry doubles the lifetime performance compared to the existing high durability model "HR-AAUTEWM".(*1) The longer life of the battery reduces the frequency of battery replacements, increasing convenience for customers. The "HR-AATEZ" will be released from April 2024. FDK offer a full lineup of nickel-metal hydride batteries for in-vehicle applications to meet most operating conditions.

All FDK nickel-metal hydride batteries are made in FDK's Japan domestic factory which is IATF 16949 certified and complies with necessary environmental requirements such as RoHS (Restriction of Hazardous Substances Directive) and EU Battery Regulation (2023/1542).

FDK, as a Smart Energy Partner, will continue to provide customers with proposals for the efficient use of electric energy in a safe and efficient manner by assembling advanced technologies.
