Its extremely small form factor makes it indispensable for compact sensors, medical devices (e.g. in diagnostics), memory backups (RTC, CMOS) on densely packed circuit boards, and for military applications. It is perfectly suited to all devices that require a long-lasting and reliable energy source, but do not offer space for a standard AA cell.Engineered for maximum safety and efficiencyThe safety and longevity of the SL-750S are based on its well-conceived construction. The cell features a hermetic glass-to-metal seal that reliably prevents the leakage of electrolyte. The inorganic electrolyte used is non-flammable and provides a high level of intrinsic safety. Every cell is designed to release its energy consistently and safely over a very long period, minimising maintenance costs and reducing the total cost of ownership of your application.Superior lithium thionyl chloride technologyLithium thionyl chloride technology (Li-SOCl₂) offers decisive advantages for long-term use. A characteristic feature is the passivation effect: a thin protective layer forms on the lithium anode, drastically reducing self-discharge and thus allowing for extremely long shelf life. This technology ensures that the energy is still almost fully available even after years of storage, setting the SL-750S apart from all other battery technologies. Features  ModelTadiran SL-750/S TechnologyLithium thionyl chloride (Li-SOCl₂) Size1/2 AA Nominal voltage (V)3.6 Capacity (mAh)1000 Max. continuous discharge current30 mA Self-dischargeapprox. 1% per year Operating temperature (°C)-55 ~ +85 Dimensions (Ø x L, mm)approx. 14.7 x 25.2 Weight (g)approx. 9 ConnectionStandard (industrial head) RechargeableNo  FAQs about this Tadiran batteryIs this battery rechargeable?No, this is a primary lithium battery and must not be recharged under any circumstances.

The Tadiran SL-2790S is a revolutionary PulsesPlus hybrid battery in the large case size DD. It was developed for the most demanding long-term applications that require both extremely 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). With an enormous capacity of 32 Ah, it is the first choice for devices that have to operate completely autonomously for many years.Highlights at a glanceExtremely high capacity: 32 Ah for maximum autonomous operating times over many years.High pulse current capability: Ideal for applications with high peak current requirements (up to 4 A).No voltage drop: The integrated HLC prevents the passivation effect under load.Maximum service life: Low self-discharge of the primary cell and gentle operation.Robust DD form factor: Standardised size for use in demanding industrial applications.Powerful in a wide range of applicationsThe Tadiran SL-2790S is the optimal energy solution for applications that must work for years to decades without maintenance and still need periodic high power for transmission processes. Its main application areas include long-term asset tracking systems for containers or rail vehicles, self-sufficient measuring buoys, seismic measuring stations, professional security and surveillance technology with high energy requirements as well as demanding military applications.The PulsesPlus technology: Maximum energy and performanceThe heart of the PulsesPlus battery is its hybrid design. The high-energy Li-SOCl₂ primary cell with 32 Ah serves as long-term energy storage and continuously charges the hybrid layer capacitor (HLC) connected in parallel. If the application requires a high current pulse, this is delivered 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 so ensures a stable voltage and maximum service life.Superior lithium hybrid technologyBy combining the best features of two technologies, the PulsesPlus battery offers unmatched benefits. 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 a power source that remains ready for use over decades and can provide high power immediately when required, even after long periods of inactivity and at low temperatures. Features  ModelTadiran SL-2790/S TechnologyPulsesPlus (Li-SOCl₂ + HLC) Case sizeDD Rated voltage (V)3.6 Capacity (mAh)32000 Max. continuous discharge current1000 mA Max. pulse current5000 mA Self-dischargeapprox. 2% per year Operating temperature (°C)-40 ~ +85 Dimensions (Ø x L, mm)approx. 33.1 x 118.0 Weight (g)approx. 135 ConnectionStandard (industrial head) RechargeableNo  FAQs about this Tadiran PulsesPlus batteryWhat exactly is the PulsesPlus technology?PulsesPlus is a hybrid system that combines a durable lithium primary battery with a rechargeable hybrid capacitor (HLC). The battery provides the energy for a very long service life, while the capacitor provides the high output 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 bursts. A typical example is a self-sufficient measuring buoy that transmits its data to a satellite once a day. A standard battery would experience a voltage drop 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 encounters the high load. As a result, the voltage drop caused by the passivation layer in standard cells is effectively avoided.Does this model have solder or wire connections?No, the model SL-2790S is the standard version with regular battery contacts and is intended for use in a suitable DD battery holder. For direct installation, Tadiran also offers versions of this cell type with different connectors.Is this system rechargeable?No, it is a primary system. The primary cell cannot be recharged from an external source. The integrated capacitor is recharged exclusively by the primary cell itself.
