Maxell CR Series Heat Resistance Battery - Wide Temp Range

Description

In industrial instrumentation and automotive engineering, temperature fluctuation is a major challenge for component reliability. The Maxell CR Series Heat Resistance Coin Lithium Manganese Dioxide Battery addresses this by incorporating highly heat-resistant material combined with Maxell’s original sealing technology.

This unique construction allows the battery to maintain integrity and voltage stability in environments that would compromise standard lithium coin cells. The design creates a power source that is supremely suitable for automobile applications, providing the durability needed for safety-critical systems. Furthermore, as the Internet of Things (IoT) expands into harsher environments, this battery provides the necessary endurance for remote sensors and loggers that must operate autonomously without maintenance.

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.
