Maxell ER Series Lithium Thionyl Chloride Battery

This battery is a high energy density sealed battery containing dangerous (Lithium) and deleterious (Thionyl Chloride) materials.

Description

A protective resistor is used to prevent the battery from being charged by large surges of current during diode failure. Please set the resistor so that the maximum current shown in the right table is not exceeded. For example, say an ER6 battery is used in sample circuit A in combination with a main power source 5 volt. Since the permitted charge current is 100μA and this battery’s voltage is 3.6V, let the resistor be R>= (5V-3.6V)/100μA=14k ohm, meaning that at least 14k ohm is required.

This battery is a high energy density sealed battery containing dangerous (Lithium) and deleterious (Thionyl Chloride) materials. For this reason, improper handling of the battery could lead to distortion, leakage*, overheating, explosion, fire, or generation of irritating/corrosive gases, causing bodily injury or equipment trouble.

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.

Features

  • High 3.6-V voltage
    The lithium thionyl chloride battery achieves a high voltage of 3.6 V.
  • Flat discharge characteristics
    The change of internal resistance during discharge is minimal, allowing for flat discharge voltage until end of discharge life.
  • High energy density
    Provides high energy density of 970m Wh/cm3 with discharge current of 100 µA (ER6 type).
  • Wide usable temperature range
    Can be used over a wide temperature range : – 55 deg. C to +85 deg. C (please consult with Maxell, if using in temperatures of -40 deg. C or less).
  • Superior long-term reliability
    The extremely low self-discharge, together with the use of a hermetic seal, allows for stable use over long periods.

Applications

  • OA Machines (Fax, Copiers, Printers)
  • Desktop PCs
  • PDAs
  • Medical Instruments, Cash Registers
  • FA Instruments (Measuring Instruments, Onboard Microcomputers, Sensors)
  • Electronic Meters (Gas, Water, Electricity)
  • ETC (Electronic Toll Collection System)
