Maxell Lithium-ion Battery Medium Sized - Prismatic Rechargeable (EOL)

Description

Maxell Lithium-ion Battery Medium Sized line was developed to meet the demanding requirements of compact, high-performance mobile devices. Utilizing Maxell’s proprietary electrode technology, these prismatic cells achieved a superior balance of thinness and high capacity, allowing for sleeker device designs without compromising operational time.

These batteries are characterized by a stable operating voltage of 3.7V—approximately three times that of traditional Nickel-Cadmium (Ni-Cd) or Nickel-Metal Hydride (Ni-MH) batteries. This high voltage output, combined with excellent energy density, made them the standard power source for smartphones, camcorders, and portable game consoles for nearly three decades.

To ensure safety and reliability, Maxell offered these cells primarily as battery packs equipped with electronic protection circuits. These circuits were critical for preventing overcharge, overdischarge, and overcurrent conditions, ensuring the battery operated safely within its wide temperature range of -20°C to +60°C. While production has ceased as Maxell shifts focus to next-generation solid-state technologies, technical support remains available for existing partners.

Brand

Maxell

Maxell was formed in 1960, when a dry cell manufacturing plant was created at the company's headquarters in Ibaraki, Osaka. In 1961, Maxell Electric Industrial Company, Limited was created out of the dry battery and magnetic tape divisions of Nitto Electric Industrial Company, Limited (now Nitto Denko Corporation).

On March 18, 2014, the company was listed on the First Section of the Tokyo Stock Exchange. In 2013, Maxell, Ltd. acquired Hitachi Consumer Electronics, Co., Ltd.’s projector design, development and manufacturing assets and resources. On October 1, 2019, Maxell Corporation of America announced it would assume responsibility for all operations related to both Hitachi- brand and Maxell-brand projector products and accessories in the North American market.
