DUSLAN ER34615 3.6V 19000mAh lithium thionyl chloride standard battery 6-pack

D-size lithium thionyl chloride pack

Six D-size ER34615 primary cells deliver 3.6 V and 19000 mAh each for long-life industrial devices such as wireless alarms, memory backup units, dive computers and night-vision gear. The lithium thionyl chloride chemistry provides high energy density and a low self-discharge rate below one percent per year at 68 °F, supporting up to ten years of shelf life. Non-flammable electrolyte and UL approval (BBCV2.MH30127) suit safety-critical installations. Spot-welded tabs on both ends simplify permanent mounting in custom assemblies.

Check voltage, current and temperature limits

Verify that the target equipment accepts a 3.6 V nominal primary cell and does not require rechargeable chemistry. Continuous draw must stay within 200 mA and pulse peaks within 400 mA to avoid damage. Confirm the operating envelope of -55 °C to +85 °C matches the deployment environment and that storage will not exceed +30 °C. Physical envelope is 34.2 mm diameter by 61.5 mm height, so ensure the battery compartment accommodates these dimensions and tab orientation.

Tabs and multi-cell quantity enable direct

Spot-welded tabs on each end remove the need for separate holders or spring contacts, allowing direct soldering or welding into PCB-mounted packs. The six-cell bundle supports series or parallel configurations for higher voltage or capacity without sourcing individual units. Compatibility with Saft LS 33600 cells simplifies cross-referencing for existing designs. Ten-year shelf life at 68 °F reduces spare-inventory rotation for maintenance teams.
