Tadiran SL-361P Lithium battery 2/3 AA with 3.6 V and 1.6 Ah, with axial wire

The Tadiran SL-361P from the iXtra series is a primary lithium thionyl chloride battery in the compact 2/3 AA size. It was specially developed for applications that require a long service life combined with a moderate current load. This version is pre-configured with axial wire (pins) for flexible and secure solder mounting. 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 wire for direct solder mounting.
• 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 lifespan.
• Wide temperature range: Reliable operation from -55 °C to +85 °C.

Powerful in a wide range of applications

The Tadiran SL-361P was specifically developed for applications where both miniaturisation and enhanced power output are crucial. The axial wire enables firm and vibration-proof integration without a battery holder. Its primary fields of application include compact radio sensors, miniaturised GPS trackers, medical monitoring devices and other professional electronics that require regular transmission pulses in the smallest space.

Engineered for maximum safety and efficiency

The safety and longevity of the SL-361P are based on the proven Tadiran design. The cell features a hermetic glass-to-metal seal, reliably preventing electrolyte leakage. The inorganic electrolyte used is non-flammable and ensures a high level of intrinsic safety. Every cell is designed to deliver its energy consistently and safely over a very long period of time, minimising maintenance costs and reducing the total cost of ownership 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 minimal continuous currents, the SL-300 series demonstrates better performance with medium load demands and pulse currents. The passivation effect is overcome more rapidly, resulting in a more stable power supply in applications that regularly "wake up" to perform tasks.
 

Features

FAQs about this Tadiran battery

What does the "axial wire" connection mean?

This model is equipped with connection wires (pins) that emerge from the centre of the positive and negative terminals of the cell. This configuration is intended for through-hole mounting on printed circuit boards (PCBs) and enables a very robust and durable solder connection.

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

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

For which applications is this battery type suitable?

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

Is this battery rechargeable?

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

What does the passivation effect mean with this battery?

After prolonged storage, a protective layer forms on the lithium surface, minimising self-discharge. The iXtra series is designed so that this layer breaks down more quickly and with less voltage drop under load than in the SL-700 series, which is advantageous for applications with regular current pulses.
