Tadiran SL-860P Lithium battery AA with 3.6 V and 2.4 Ah, with axial pins

The Tadiran SL-860P is a primary high-performance lithium thionyl chloride battery in the widely used size AA (Mignon). It was designed for professional applications that require a very high capacity and a long service life. This version is pre-fitted with axial pins for flexible and safe solder mounting. With a nominal voltage of 3.6 V and a very high capacity of 2.4 Ah, it is a reliable energy solution for long-life electronic devices.

Highlights at a glance

• Very high capacity: 2.4 Ah for a maximally extended and self-sufficient operating time.
• Ready to install: With robust, axial pins for direct and safe soldering.
• High nominal voltage: Stable voltage level of 3.6 V for almost the entire service life.
• Maximum reliability: Proven long-term stability and low self-discharge.
• Wide temperature range: Reliable operation from -55 °C to +85 °C.

Powerful in a wide range of applications

The Tadiran SL-860P has been specially developed for long-term applications where the battery is firmly and vibration-proof integrated into electronics. The axial pins allow a fixed integration without a battery holder. Its primary fields of application include memory backups (RTC, CMOS) in industrial controllers (PLC), metering technology (metering for water, gas, electricity), professional security technology and long-life radio sensors.

Designed for maximum safety and efficiency

The safety and service life of the SL-860P are based on the proven Tadiran design. The cell features a hermetic glass-to-metal seal that reliably prevents electrolyte leakage. The inorganic electrolyte used is non-flammable and ensures a high degree of intrinsic safety. Each cell is designed to deliver its energy constantly and safely over a very long period of time, minimising maintenance costs and lowering the total operating costs of your application.

Superior lithium thionyl chloride technology

Lithium thionyl chloride technology (Li-SOCl₂) is the gold standard for long-term applications with low current requirements. A characteristic feature is the passivation effect: a thin protective layer forms on the lithium anode, which reduces self-discharge to an absolute minimum, thus enabling extremely long storage and operating capability. This ensures that the energy is still reliably available even after many years.

FAQs about this Tadiran battery

What does the connection with "axial pins" mean?

This model is equipped with connecting wires (pins) that exit centrally from the positive and negative poles of the cell. This configuration is designed for through-hole mounting on printed circuit boards (PCBs) and enables a very robust and permanent solder connection.

For which applications is this battery type suitable?

This battery type is ideally suited for professional electronics where the battery is soldered in place and extremely long service life is crucial. Typical applications include meters, industrial computers, alarm systems and long-life sensors.

Is this battery rechargeable?

No, this is a primary lithium battery and must not under any circumstances be recharged. Attempting to charge the cell is dangerous and can lead to overheating, leakage, or bursting of the cell.

What does the passivation effect mean for this battery?

After prolonged storage, a protective layer forms on the lithium surface. This layer is the reason for the extremely low self-discharge. On first use, especially with higher currents, it can cause a short voltage delay. This should be considered in the circuit design of the application.

What is the shelf life of the battery and how should it be stored?

The battery has a shelf life of over 10 years. For maximum shelf life, we recommend storing in a cool, dry place with low humidity.
