Primary lithium D cell

The SAFT LSH20 D 3.6V primary lithium cell uses Lithium-Thionyl chloride chemistry with concentric bobbin electrodes that maximise active material loading for high energy density. It is intended for equipment that requires a single D-sized power source with a stable 3.6 V output.

Un-fused cell with safety vent

Each cell is housed in a stainless steel container and includes a built-in safety vent designed for the D form factor. The un-fused construction means the cell delivers its full capability directly, so the host device must provide any required current limiting or protection circuitry.

Stainless steel container and bobbin build

The robust stainless steel can and bobbin electrode layout are engineered for long shelf life and reliable operation in fixed installations. The standard D dimensions allow direct replacement in existing battery holders, while the safety vent adds a mechanical safeguard without altering the mounting footprint.

Questions about this item

How often will the 3.6V lithium-thionyl chloride cell need replacement in a low-drain device?

The 20 Ah capacity and bobbin construction give very low self-discharge, so the cell typically lasts several years before replacement is required.

What limits continuous current delivery from the bobbin-type D cell?

The concentric electrode design maximises energy density but restricts high-rate discharge, so sustained high current is the first limitation.

Does the stainless steel container and safety vent keep the cell cool during all-day operation?

The safety vent prevents pressure build-up, while the stainless steel container dissipates modest heat; the cell runs cool at its rated low-drain currents.
