DUSLAN ER18505 3.6V 3600mAh Lithium Primary Battery

Primary Lithium Battery 3600 mAh

The DUSLAN ER18505 is a 3.6 Volt primary lithium thionyl chloride cell rated at 3600 mAh. It is intended for low-drain devices that require long-term, maintenance-free power such as utility meters, medical instruments, telemetry modules and LED lighting systems. The chemistry delivers a stable nominal voltage of 3.6 Volt across a wide temperature range. This battery is not rechargeable and must not be recharged.

Verify Voltage Polarity And Mounting

Confirm that the target equipment specifies a 3.6 Volt primary lithium cell and that the 18.5 mm diameter by 50.5 mm height form factor fits the battery compartment. Check that the operating envelope of minus 55 to plus 85 Celsius matches the installation environment. Ensure the PCB layout accommodates tab soldering completed within a few seconds and avoid mixing this model with other battery types in series.

Non Rechargeable Chemistry

The lithium thionyl chloride chemistry provides high energy density and a low self-discharge rate suited for multi-year backup duty. Because the cell is not rechargeable, it eliminates charging circuitry but requires replacement once depleted. Storage below 30 Celsius in a clean, dry, ventilated area preserves capacity. A brief 100 mA discharge can stabilise voltage if the open-circuit reading falls below the application threshold.
