Cylindrical lithium-thionyl chloride battery Maxell Europe

Maxell ER (lithium thionyl chloride) batteries are available only for equipment manufacturers as a built-in part. Therefore, Maxell does not supply these batteries for replacement directly to users of equipment with these batteries. When built-in ER batteries need to be replaced, please contact your equipment manufacturer. If you are planning to use Maxell ER batteries in your equipment as a built-in part, please contact Maxell.

This battery is ideal for such long-term applications as power for electronic devices and electric power, water, and gas meters, and especially as a backup power source for memory ICs.

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.
