Tadiran SL-2770S PulsesPlus battery C with 3.6 V and 7.2 Ah

The Tadiran SL-2770S is a revolutionary PulsesPlus hybrid battery in the standard size C (Baby). It was specially developed for modern electronic applications that require both a long service life 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 offers a high energy reserve for long-term applications, with 7.2 Ah.

Highlights at a glance

• High pulse current capability: Ideal for applications with high peak current requirements (up to 1.5 A).
• No voltage drop: The integrated HLC prevents the passivation effect under load.
• Very high capacity: 7.2 Ah from the primary cell for extremely long, self-sufficient runtimes.
• Maximum service life: The primary cell is only minimally stressed, which maximises longevity.
• Robust C (Baby) design: Standardised size for use in demanding industrial applications.

Powerful in a wide range of applications

The Tadiran SL-2770S is the optimal energy solution for demanding applications that spend most of their time in standby mode but periodically require high performance for transmissions. Its primary areas of use include modern radio modules (GSM, LTE, IoT), professional asset tracking systems, emergency call systems (eCall), security and surveillance technology, as well as military communication equipment. Wherever a standard lithium battery would collapse under pulse load, PulsesPlus technology provides reliable performance.

PulsesPlus technology: Maximum energy and performance

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

Superior lithium hybrid technology

By combining the best features of two technologies, the PulsesPlus battery offers unequalled advantages. It combines the high energy density and low self-discharge of a lithium thionyl chloride cell with the high power density of a capacitor. The result is a power source which remains operational for over 10 years and can deliver high power instantly when required, even after long idle times and at low temperatures.
 

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 layer capacitor (HLC). The battery provides the energy for extremely long life, while the capacitor delivers the high performance 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 current pulses. A typical example is an asset tracker that sends its position via mobile once a day. A standard battery would experience a voltage drop during such a transmission pulse, but the PulsesPlus battery would not.

Does PulsesPlus completely prevent the passivation effect?

Yes, from an application perspective, the passivation effect is completely eliminated. As the high current pulse is supplied by the HLC and not by the primary cell, the primary cell never faces the high load. Thus, the voltage drop that occurs in standard cells due to the passivation layer is effectively avoided.

Does this model have solder terminals or wires?

No, the model SL-2770S is the standard version with normal battery contacts and is intended for use in a suitable C battery holder. For direct installation, Tadiran also offers versions of this cell type with various connectors.

Is this system rechargeable?

No, it is a primary system. The primary cell cannot be recharged by an external source. The integrated capacitor is recharged exclusively by the primary cell itself.
