SAFT

SAFT LS17500 3.6V 3600mAh Lithium Battery 8-Pack

SKU CH-YTQ3-QCQ59

Eight lithium thionyl chloride cells deliver 3.6 V and 3600 mAh each, operating from -60 °C to +85 °C with a low self-discharge rate

  • Reliable power for up to 25 years of proven production
  • High 3600 mAh capacity with stable 3.6 V output
  • Operates from -60 °C to +85 °C for extreme environments
  • Low self-discharge under 1 % per year at 20 °C
  • Safe non-flammable electrolyte with hermetic glass-to-metal seal

Pack contents and chemistry

This pack contains eight SAFT LS17500 lithium thionyl chloride cells, each rated at 3.6 volt nominal and 3600 mAh capacity. The bobbin construction with hermetic glass-to-metal sealing delivers a non-flammable electrolyte and UL approval under file MH30127. The cells measure 17 mm diameter by 50.9 mm height and weigh 21.9 g each.

Suitable and unsuitable uses

The high operating voltage, low self-discharge below 1% per year at 20 °C and wide temperature range from -60 °C to +85 °C suit long-life metering, remote sensors and industrial data loggers. Devices that demand continuous currents above 120 mA or require rechargeable chemistry should look at alternative power sources.

Sustained-load behaviour

Under a typical 1 mA load the voltage remains stable near 3.6 volt for most of the service life, while pulse capability reaches 120 mA. Passivation resistance and corrosion-resistant electrolyte maintain capacity over multi-year deployments, with less than 1% capacity loss during storage before use.

Questions about this item

What device slot accepts the 17 mm diameter by 50.9 mm height A-size cell?

Any equipment designed for an A-size (ER17500) primary lithium cell with a 17 mm diameter and 50.9 mm height will accept these batteries.

Can the 3.6 V nominal voltage replace 3.6 V ½ AA or AA lithium thionyl chloride cells in older equipment?

No, the larger A-size dimensions and higher 3600 mAh capacity prevent direct substitution for smaller ½ AA or AA cells.

How can I verify the pack is fresh after storage?

Measure open-circuit voltage; a reading near 3.66 V at 20 °C indicates the less-than-1%-per-year self-discharge has kept cells at full capacity.
