A 3.6 V, 1650 mAh lithium-thionyl chloride 2/3 AA cell for board-level backup, meters, medical and industrial gear

  • Battery type2/3 AA
  • 1650 mAh capacity powers devices for extended periods
  • Lithium-thionyl chloride chemistry operates from -55 °C to +85 °C
  • 6 V nominal voltage suits memory-backup and metering circuits
  • 5 mm × 33.5 mm 2/3 AA size fits standard holders
  • 70 mA continuous and 140 mA pulse current handles low-drain loads

DUSLAN ER14335 2/3 AA Lithium Primary Cell

This 3.6 V lithium-thionyl chloride battery delivers 1650 mAh in a 2/3 AA form factor. It suits engineers and technicians needing reliable primary power for metering, medical, military or telecom equipment. The cell operates from -55 °C to +85 °C and weighs 14 g. It is not rechargeable and must not be charged.

Replaces older 1/2 AA

Upgrading makes sense when a device demands the 1650 mAh capacity or the 70 mA continuous and 140 mA pulse current ratings. The jump is worth it for boards that previously depleted smaller primaries too quickly. Do not mix this model with different cells in series. Buyers who need a rechargeable chemistry or higher continuous current cannot use this product.

Limited by 70 mA continuous and 140 mA pulse current

The lithium-thionyl chloride chemistry supports low-drain, long-life backup rather than high-power loads. Exceeding the rated currents can damage the cell. Storage must stay below +30 °C in a dry, ventilated area. Solder tabs only for a few seconds to avoid heat damage. Users requiring sustained currents above 140 mA or a rechargeable solution must choose a different technology.
