Maxell Lithium Thionyl Chloride Battery ER3 ER 17/33 ER 6

  • High 3.6-V voltage
  • Flat discharge characteristics
  • High energy density and wide usable temperature range
  • Superior long-term reliability
  • Available models: ER3, ER6, ER 17/33



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.
