Tadiran SL-361PT lithium battery 2/3 AA with 3.6 V and 1.6 Ah, with pins +1/-2

The Tadiran SL-361PT from the iXtra series is a primary lithium thionyl chloride battery in the compact 2/3 AA format. It was specially developed for applications that require a long service life in combination with moderate current-carrying capacity. This version is pre-assembled with axial pins for flexible and secure soldering assembly. 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

• Ready to install: With robust, axial pins for direct soldering assembly.
• Compact and powerful: Optimised for moderate loads in the compact 2/3 AA format.
• High capacity: 1.6 Ah for long runtimes in compact devices.
• High rated voltage: Stable voltage position of 3.6 V for almost the entire service life.
• Wide temperature range: Reliable operation from -55 °C to +85 °C.

Powerful in diverse applications

The Tadiran SL-361PT was specifically developed for applications where both miniaturisation and enhanced power output are essential. The axial pins allow for solid and vibration-resistant integration without a battery holder. Its primary areas of application include compact wireless sensors, miniaturised GPS trackers, medical monitoring devices and other professional electronics that require regular pulse transmission in very confined spaces.

Engineered for maximum safety and efficiency

The safety and longevity of the SL-361PT 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 constantly and safely over a very long period, minimising maintenance costs and reducing the overall operating costs of your application.

iXtra Series: The technology for higher performance

The iXtra series from Tadiran is designed to offer improved voltage stability under load. Compared to the standard series (SL-700), which is optimised for minimal continuous currents, the SL-300 series demonstrates better behaviour under medium load conditions and pulse currents. The passivation effect is thus overcome more quickly, resulting in more stable power supply in applications that regularly "wake up" to perform tasks.
 

Features

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 intended for through-hole mounting on printed circuit boards (PCBs) and allows a very robust and permanent soldered connection.

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 minimum continuous current, such as for pure memory backup applications.

For which applications is this battery type suitable?

This battery type is ideally suited for miniaturised electronics, where the battery is permanently soldered and a long service life with regular power requirements is essential. Examples include compact wireless sensors, miniature medical devices and GPS trackers.

Is this battery rechargeable?

No, this is a primary lithium battery and must never be recharged under any circumstances. Attempting to recharge the cell is dangerous and can lead to overheating, leakage or rupture of the cell.

What does the passivation effect mean for this battery?

After prolonged storage, a protective layer forms on the lithium surface, which minimises self-discharge. The iXtra series is designed to ensure that this layer is broken down faster and with lower voltage drop under load than with the SL-700 series, which is advantageous for applications with regular pulse currents.
