Tadiran SL-750PR Lithium battery 1/2 AA with 3.6 V and 1.0 Ah, with radial pins

The Tadiran SL-750PR is a primary high-performance lithium-thionyl chloride battery in the extremely compact size 1/2 AA. As part of the proven SL-700 series, it is optimised for maximum reliability and an extremely long service life with minimal self-discharge. This version is preassembled with radial pins for specific and secure mounting on PCBs, making it ideal for miniaturised "fit and forget" applications.

Highlights at a glance

• Maximum longevity: Extremely low self-discharge of less than 1% per year.
• For PCB mounting: Preassembled with radial pins for direct installation.
• Extremely compact design: 1/2 AA size for maximum miniaturisation of your application.
• High rated voltage: Stable voltage of 3.6 V during 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-750PR has been specifically developed for long-term applications with low continuous current, where the battery is permanently integrated into the electronics and the installation space is limited. The radial pins allow a specific and space-saving arrangement on the PCB. The main areas of application are memory backups (RTC, CMOS) in compact industrial controllers, miniaturised metering technology and long-life wireless safety sensors.

Designed for maximum safety and efficiency

The safety and longevity of the SL-750PR are based on the proven Tadiran design. The cell has a hermetic glass-to-metal seal that reliably prevents electrolyte leakage. The inorganic electrolyte used is non-flammable and ensures a high level of intrinsic safety. Each cell is designed to deliver its energy consistently and safely over a very long period, minimising maintenance costs and reducing the overall operating costs of your application.

Superior lithium-thionyl chloride technology

The lithium-thionyl chloride technology (Li-SOCl₂) of the SL-700 series is the gold standard for long-term applications with low power requirements. A characteristic feature is the passivation effect: a thin protective layer forms on the lithium anode, reducing the self-discharge to an absolute minimum and thus enabling extremely long storage and operating periods. This ensures that the energy is reliably available even after many years.

FAQs about this Tadiran battery

What does the connection with "radial pins" mean?

In contrast to axial connections, which emerge from the centre of the terminals, radial pins are arranged so that they emerge from one 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 advantage of the SL-700 series compared to other series?

The SL-700 series is optimised for the absolute lowest self-discharge. It is the best choice for applications that need very little power over many years, such as memory backup. In contrast, other series (such as the SL-300 iXtra) are designed for applications with higher pulse current requirements.

For which devices is this battery type suitable?

This battery type is ideal for miniaturised professional electronics, where the battery is permanently soldered and an extremely long service life is crucial. Typical applications are compact counters, industrial mini controllers and long-life safety sensors with specific PCB layouts.

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 longer storage, a protective layer forms on the lithium surface. This layer is the reason for the extremely low self-discharge. During the first load, it can cause a short voltage delay. This should be taken into account in the circuit design for applications that require current immediately after activation.
