Saft Lithium round cell LSH20 with Z solder tag, 3.6 V and 13.0 Ah

The Saft LSH20 with Z solder tag is a high-performance lithium thionyl chloride battery (Li-SOCl2) in size D, designed for horizontal mounting on printed circuit boards. It combines the spiral-shaped high-performance technology of the LSH series with a flat, space-saving installation. With a nominal voltage of 3.6 V and a very high capacity of 13.0 Ah, it is the ideal choice for demanding devices that require an extremely high energy output and a compact design.

Highlights at a glance

• Flat mounting: Z-shaped solder terminals for horizontal PCB mounting
• Maximum power: Developed for highest continuous currents up to 1800 mA
• Extremely high capacity: 13.0 Ah in the D size for maximum runtime under load
• Highest pulse capacity: Reliable delivery of pulses up to 4000 mA (4 A)
• Spiral technology: Optimised for fast energy output with minimal voltage drop
• Robust: Hermetically sealed stainless steel housing for maximum operational safety

Maximum power for compact applications

The Saft LSH20 with Z solder tag was specially developed for use in professional devices where a low height and extremely high performance are crucial. The Z-shaped connections allow the battery to be soldered horizontally directly onto the circuit board. It is ideal for emergency transmitters, military equipment and high-performance industrial applications with limited installation space.

Superior spiral technology for maximum currents

In contrast to batteries with a wound design (bobbin type), the spiral design of the LSH20 maximises the active electrode surface. This enables a significantly faster chemical reaction and therefore the delivery of extremely high currents with stable voltage behaviour. This ensures reliable and constant performance of your application even under the highest load.

Efficiency and guaranteed safety

The cell is hermetically sealed with a glass-to-metal seal to minimise the risk of current leakage and has a non-flammable electrolyte, which significantly increases operational safety. The LSH20 conforms to the IEC 60086-4 safety standard and is UL certified, making it suitable for safety-critical applications with the highest power requirements.

FAQs about the Saft LSH20 with Z solder tag

What is the advantage of a Z solder tag?

The Z-shaped solder tag is specially designed for horizontal (flat) mounting of the battery on a printed circuit board. This enables a very low installation height and is ideal for compact electronic devices where vertical installation space is limited.

What is the main difference to the Saft LS33600?

Although both batteries are size D, they are optimised for opposing purposes. The LSH20 is designed for maximum power and extremely high current output. The LS33600 is optimised for an extremely long service life with very low power consumption and offers a higher capacity.

For which applications is this battery particularly suitable?

This version is optimal for all high-performance applications where a long-life battery is required and a very flat design is needed at the same time. Examples are compact emergency transmitters, flat sensor modules, or high-performance memory modules.

Does the LSH20 have a higher self-discharge rate than an LS battery?

Yes, due to the spiral-shaped design with a larger electrode surface, the self-discharge of the LSH series tends to be slightly higher than that of the LS series. Nevertheless, it offers excellent shelf life and durability for a high-performance battery.

Is the LSH20 with Z solder tag rechargeable?

No, this is a lithium primary battery, which is not rechargeable. Any attempt to recharge the battery is dangerous and may result in destruction of the cell or deflagration.
