Tadiran SL-2780P PulsesPlus battery D with 3.6 V and 16.5 Ah, with axial wire

The Tadiran SL-2780P is a revolutionary PulsesPlus hybrid battery in the standard size D (mono). It was developed for demanding long-term applications that require both a very high energy reserve and the ability to deliver high current pulses. The system combines a long-life lithium-thionyl chloride primary cell with a unique hybrid layer capacitor (HLC). This version is pre-assembled with axial wire (pins) for a fixed and vibration-proof installation.

Highlights at a glance

• High pulse current capability: Ideal for applications with high peak current requirements (up to 3 A).
• No voltage drop: The integrated HLC prevents the passivation effect under load.
• Very high capacity: 16.5 Ah from the primary cell for extremely long, self-sufficient runtimes.
• Ready to install: With robust, axial wire for direct and safe solder mounting.
• Maximum service life: Low self-discharge of the primary cell and gentle operation.

Powerful in a wide range of applications

The Tadiran SL-2780P is the optimum energy solution for applications that must operate for years or even decades without maintenance and periodically require high power for transmission processes. Its primary areas of use include long-term asset tracking systems, self-sufficient measuring buoys, seismic measuring stations, professional security and surveillance technology with high energy requirements and demanding military applications in which the energy source is permanently soldered.

PulsesPlus technology: Maximum energy and performance

The core of the PulsesPlus battery is its hybrid design. The high-energy Li-SOCl₂ primary cell with 16.5 Ah serves as long-term energy storage and continuously charges the parallel-connected hybrid layer capacitor (HLC). If the application requires a high current pulse, this is supplied directly by the HLC, not by the primary cell. This intelligent system protects the primary cell from high loads, prevents the typical voltage drop due to passivation and thus ensures a stable voltage and maximum service life.

Superior lithium hybrid technology

By combining the best features of two technologies, the PulsesPlus battery offers unrivalled advantages. It combines the extremely high energy density and low self-discharge of a lithium-thionyl chloride cell with the high power density of a capacitor. The result is an energy source that remains operational for decades and can deliver high power immediately when required, even after long periods of inactivity and at low temperatures.
 

Characteristics

FAQs about this Tadiran PulsesPlus battery

What exactly is PulsesPlus technology?

PulsesPlus is a hybrid system that combines a long-life lithium primary battery with a rechargeable hybrid capacitor (HLC). The battery provides the energy for an extremely long service life, while the capacitor provides the high power for current pulses.

For which applications is a PulsesPlus battery better than a standard lithium battery?

It is ideal for devices that usually consume very little power but periodically require short, high power surges. A typical example is an asset tracker that sends its position once a day via mobile radio. The voltage of a standard battery would collapse with this transmission pulse, but not the PulsesPlus battery.

Does PulsesPlus completely prevent the passivation effect?

Yes, from the application's point of view, the passivation effect is completely eliminated. Since the high current pulse is supplied by the HLC and not by the primary cell, the primary cell never experiences the high load. This effectively avoids the voltage dip that occurs in standard cells due to the passivation layer.

What does the "axial wire" connection mean?

This model is equipped with connection wires (pins) that emerge centrally from the positive and negative terminals of the cell. This configuration is intended for through-hole mounting (Through-Hole) on printed circuit boards (PCBs) and enables a very robust and durable soldered connection.

Is this system rechargeable?

No, this is a primary system. The primary cell cannot be recharged from an external source. The integrated capacitor is charged only by the primary cell itself.
