SAFT LSH20 3.6V D 13000mAh Lithium Battery

SKU CH-K9BQ-7NFQ4

A 3.6V D-size lithium thionyl chloride cell delivering 13Ah capacity with a 10+ year shelf life and -60°C to +85°C operation

  • Battery typeLSH20
  • 10-year shelf life keeps power ready when needed
  • 13000 mAh capacity delivers long runtime for demanding devices
  • Operates from -60°C to +85°C for extreme environments
  • Less than 1% annual self-discharge preserves charge during storage
  • Non-flammable electrolyte enhances safety in critical applications

High-Capacity D-Cell Lithium Thionyl Chloride Power

The Saft LSH20 is a 3.6-volt D-size primary cell delivering 13 Ah of capacity. It suits industrial metering, remote sensors, and memory-backup systems that demand multi-year service without maintenance.

Straightforward Button-Top Installation

The button-top termination fits standard D-cell holders with correct polarity alignment. The non-pressurised, non-flammable electrolyte eliminates venting concerns, yet the chemistry is corrosive if the case is breached. Do not solder directly to the cell; use a dedicated holder or spot-welded tabs to avoid heat damage.

13 Ah Reserve for Low-Drain Long Life

At the rated 1.8 A continuous current the cell supports periodic telemetry bursts and low-power microcontrollers for extended intervals. The 4 A pulse capability handles brief transmission peaks. Capacity drops sharply above the 1.8 A continuous limit, so high-drain motors or constant bright LEDs will exhaust the reserve prematurely.

Questions about this item

How do I verify the SAFT LSH20 is delivering its rated 3.6 Volt output after installation?

Measure the open-circuit voltage with a multimeter; a fresh cell should read at or above 3.6 Volt, and under a 1.8 Amp continuous load the voltage should remain stable within the specified operating range.

What is included with the SAFT LSH20 D cell and what must be sourced separately?

The box contains the single 3.6 Volt 13 Ah D-size lithium thionyl chloride cell with button-top termination; any holder, wiring, or protection circuitry required for your application is not included.

Which capacity version of the SAFT LSH20 D cell should I choose for maximum runtime?

The LSH20 is offered in a single 13 Ah capacity, providing the highest nominal capacity available in this D-size lithium thionyl chloride chemistry.
