Three cylindrical 2/3 AA lithium batteries in silver metal finish

Omnicel

Omnicel ER14335 3.6V 1650mAh 2/3 AA Lithium 3-Pack

SKU CH-WR46-SSD9E

Three 2/3 AA lithium thionyl chloride cells deliver 3.6 V and 1650 mAh each for long-life industrial use

  • 6 V nominal voltage powers compatible devices reliably
  • 1650 mAh capacity supports long runtime in low-drain applications
  • 75 mA continuous and 150 mA pulse current handle steady and peak loads
  • Operating range from -55 °C to +85 °C suits extreme environments
  • UL approved chemistry meets recognised safety standards

Three-cell pack for low-drain devices

This pack contains three Omnicel ER14335 primary lithium thionyl chloride cells, each rated at 3.6 V and 1650 mAh. The 2/3 AA form factor measures 14.5 mm diameter by 33.5 mm height. They are UL approved and weigh 14 g each, supplied new in a three-piece pack.

Suits metering and memory-backup roles

The 75 mA continuous and 150 mA pulse limits suit utility meters, alarm panels, data loggers and real-time clock backup. Devices that draw higher sustained current or need a rechargeable cell should look at a different chemistry.

Steady output across wide temperature range

Nominal voltage holds at 3.6 V at 1 mA load from -55 °C to +85 °C, with open-circuit voltage of 3.66 V at +20 °C. Storage below +30 °C preserves shelf life during long deployments.

Questions about this item

What device slot fits the 14.5 mm diameter and 33.5 mm height of these ER14335 cells?

The 2/3 AA form factor measures 14.5 mm across and 33.5 mm tall, matching equipment designed for that exact size.

Can I mix these 3.6 V lithium cells with older 1.5 V AA batteries in the same device?

No. The supplier warns against using different models in series; mixing chemistries and voltages can damage the equipment.

How do I confirm the pack delivers the rated 1650 mAh after installation?

Measure open-circuit voltage at 20 °C — it should read about 3.66 V — then apply a 1 mA load and verify the voltage holds near 3.6 V.
