Tadiran SL-350PR Lithium battery 1/2 AA with 3.6 V and 1.2 Ah, with radial pins

The Tadiran SL-350PR from the iXtra series is a primary lithium thionyl chloride battery in the extremely compact 1/2 AA size. It was specially developed for miniaturised applications that require long life in combination with moderate current capability. This version is pre-assembled with radial pins for a specific and secure mounting on PCBs. With 3.6 V nominal voltage and 1.2 Ah capacity, it is the ideal energy solution for professional, space-critical electronics.

Highlights at a glance

• For PCB mounting: Pre-assembled with radial pins for direct installation.
• Compact and powerful: Optimised for moderate loads in the miniaturised 1/2 AA size.
• High capacity: 1.2 Ah for long runtimes in small devices.
• High rated voltage: Stable voltage of 3.6 V throughout almost the entire service life.
• Wide temperature range: Reliable operation from -55 °C to +85 °C.

Powerful in a wide range of applications

The Tadiran SL-350PR was specifically developed for applications where both miniaturisation and improved performance are essential. The radial pins enable a specific and space-saving arrangement on the PCB. Its primary areas of application include compact wireless sensors, miniaturised GPS trackers, medical monitoring devices and other professional electronics that require regular transmission pulses in the smallest spaces.

Designed for maximum safety and efficiency

The safety and durability of the SL-350PR 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 delivers a high level of intrinsic safety. Each cell is designed to consistently and safely deliver its energy over a very long period, which minimises maintenance costs and lowers the overall 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 minimal continuous currents, the SL-300 series performs better under medium load demands and pulse currents. The passivation effect is thus overcome more quickly, resulting in a more stable energy supply for applications that regularly "wake up" to perform tasks.

FAQs about this Tadiran battery

What does connection with "radial pins" mean?

In contrast to axial connections, which emerge centrally from the poles, radial pins are arranged so that they exit from one end face of the battery. This configuration is optimised for specific layouts on printed circuit boards (PCBs) 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, which this cell belongs to, is optimised for applications with moderate power requirements (e.g. wireless sensors). It offers more stable voltage under load. The SL-700 series, on the other hand, is designed for long-term use with minimal continuous current, such as for pure memory backup applications.

For which applications is this battery type suitable?

This battery type is ideal for miniaturised electronics where the battery is permanently soldered in and a long service life with regular power demand is essential. Example applications include compact wireless sensors, small medical devices and GPS trackers with specific PCB layouts.

Is this battery rechargeable?

No, this is a primary lithium battery and must not be recharged under any circumstances. Attempting to charge the cell is dangerous and can result in 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 that minimises self-discharge. The iXtra series is designed such that this layer is broken down more quickly under load and with less voltage drop than the SL-700 series, which is advantageous for applications with regular current pulses.
