SKU CH-FJQ9-H2W7D

A 2/3 AA lithium thionyl chloride cell delivering 3.6 V and 1650 mAh for backup, metering, medical or industrial use

  • Reliable 3.6 V output backed by 1650 mAh capacity
  • Operates from -55 °C to +85 °C for extreme environments
  • UL approved chemistry meets safety standards
  • Compact 14.5 mm × 33.5 mm size fits tight spaces
  • Low 75 mA continuous current suits long-life backup roles

2/3 AA lithium primary cell

The Omnicel ER14335 is a 3.6 V lithium thionyl chloride battery with a nominal capacity of 1650 mAh. It suits equipment that demands long-term, low-current power such as backup circuits, meters, medical devices and military or aerospace systems.

Continuous current limited to 75 mA

The chemistry delivers a maximum continuous current of 75 mA and a pulse current of 150 mA. It is not rechargeable and must not be charged; attempting to recharge creates a safety hazard.

Hermetic cylindrical format 14.5 mm by 33.5 mm

The cell measures 14.5 mm in diameter and 33.5 mm in height, weighing approximately 14 g. It operates from -55 °C to +85 °C and should be stored below +30 °C in a dry, ventilated area. Solder tabs directly only for a few seconds to avoid heat damage.

Questions about this item

Should I choose this 1650 mAh ER14335 or a different capacity for my meter?

This ER14335 cell delivers 1650 mAh at 3.6 V; select it when your device specifies that capacity and the 2/3 AA form factor.

What does the 3.6 V nominal voltage mean once the battery is installed?

At a 1 mA load and 20 °C the cell holds 3.6 V; voltage will sag under higher current and rise to 3.66 V open-circuit.

What current limits does the Li-SOCl2 chemistry impose in practice?

Continuous draw is capped at 75 mA and pulse peaks at 150 mA; exceeding either can damage the cell.
