Tadiran SL-361PR Lithium battery 2/3 AA with 3.6 V and 1.6 Ah, with radial pins

The Tadiran SL-361PR from the iXtra series is a primary lithium thionyl chloride battery in the compact 2/3 AA format. It was specially developed for applications requiring a long service life in combination with moderate current capacity. This version comes pre-configured with radial pins for specific and secure mounting on PCBs. With 3.6 V nominal voltage and 1.6 Ah capacity, it is the ideal energy solution for professional, miniaturised electronics.

Highlights at a glance

• For PCB mounting: Pre-configured with radial pins for direct installation.
• Compact and powerful: Optimised for moderate loads in the compact 2/3 AA size.
• High capacity: 1.6 Ah for long runtimes in compact devices.
• High rated voltage: Stable voltage of 3.6 V throughout almost the entire operating life.
• Wide temperature range: Reliable operation from -55 °C to +85 °C.

Powerful in a variety of applications

The Tadiran SL-361PR was specifically developed for applications where both miniaturisation and enhanced power delivery are crucial. The radial pins allow specific and space-saving arrangement on the PCB. Its main areas of application include compact wireless sensors, miniaturised GPS trackers, medical monitoring equipment, and other professional electronics that require regular transmission pulses in extremely small formats.

Engineered for maximum safety and efficiency

The safety and longevity of the SL-361PR are based on Tadiran's proven design. The cell features a hermetic glass-to-metal seal that reliably prevents electrolyte leakage. The inorganic electrolyte used is non-flammable and provides a high level of intrinsic safety. Each cell is designed to deliver its energy consistently and safely over a very long period of time, reducing maintenance costs and lowering the total operating costs of your application.

iXtra series: The technology for higher performance

The iXtra series from Tadiran is designed to provide improved voltage stability under load. Compared to the standard series (SL-700), which is optimised for very low continuous currents, the SL-300 series behaves better with moderate load requirements and pulse currents. The passivation effect is thus overcome more quickly, resulting in more stable power in applications that regularly "wake up" to perform tasks.

FAQs about this Tadiran battery

What does the connection with "radial pins" mean?

In contrast to axial connections, which exit centrally from the terminals, radial pins are arranged so that they leave from one face of the battery. This configuration is optimised for specific PCB (printed circuit board) layouts and enables particularly stable and defined mounting of the cell.

What is the difference between the SL-300 (iXtra) and the SL-700 series?

The SL-300 (iXtra) series, to which this cell belongs, is optimised for applications with moderate current requirements (e.g. wireless sensors). It offers more stable voltage under load. The SL-700 series, on the other hand, is designed for absolute long-term use with the lowest continuous current, such as memory backup applications.

For which applications is this battery type suitable?

This battery type is ideal for miniaturised electronics where the battery is soldered in place and a long service life with regular power requirements is crucial. Examples include compact wireless sensors, small medical devices, and GPS trackers with special PCB designs.

Is this battery rechargeable?

No, this is a primary lithium battery and must never be recharged under any circumstances. Attempting to charge the cell is dangerous and can result in overheating, leaks, or bursting of the cell.

What does the passivation effect mean in this battery?

After long storage, a protective layer forms on the lithium surface, which minimises self-discharge. The iXtra series is constructed so that this layer is reduced under load faster and with lower voltage drop than in the SL-700 series, which is beneficial for applications with regular current pulses.
