Maxell ER Series Lithium Thionyl Chloride Battery - End-of-Life

Description

Maxell ER Series comprises Lithium Thionyl Chloride (Li-SOCl2) batteries, a chemistry often chosen for its high voltage and energy density in industrial settings. The series included various cylindrical models, such as the ER6, ER17/50, and ER3 types, designed to meet diverse power requirements.

End-of-Life Product Notice Management has decided to discontinue the sales of Lithium Thionyl Chloride Batteries (ER) due to future market trends. This strategic shift means that the ER series is no longer part of the active sales catalog.

However, recognizing the long operational lifecycles of industrial equipment, Maxell ensures continued support to customers who have already purchased the product. This legacy support is intended to assist engineering and procurement teams in managing the lifecycle of their existing assets.

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.
