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

The Tadiran SL-750PT 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 preconfigured with axial pins for flexible and secure solder assembly, 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.
• Ready to install: With robust, axial pins for direct solder assembly.
• Extremely compact design: 1/2 AA size for maximum miniaturisation of your application.
• High rated voltage: Stable voltage of 3.6 V during nearly 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-750PT was specifically developed for long-term applications with low continuous current, where the battery is firmly integrated into the electronics and the installation space is limited. The axial pins enable flexible integration into the circuit. Its primary fields of application include memory backups (RTC, CMOS) in compact industrial controls, miniaturised metering technology, and durable wireless security sensors.

Designed for maximum safety and efficiency

The safety and longevity of the SL-750PT are based on the proven Tadiran design. The cell features a hermetic glass-to-metal seal that reliably prevents leakage of the electrolyte. 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, which minimises maintenance costs and reduces the total 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 current requirements. A characteristic feature is the passivation effect: a thin protective layer forms on the lithium anode, which reduces self-discharge to an absolute minimum and thus enables extremely long shelf and operating life. This ensures that the energy is reliably available even after many years.

FAQs about this Tadiran battery

What does the connection with "axial pins" mean?

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

What is the advantage of the SL-700 series over other series?

The SL-700 series is optimised for the absolutely lowest self-discharge. It is the best choice for applications that require very little current over many years, such as memory retention (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, miniature industrial controllers, and long-life security sensors.

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 may result in overheating, leakage or bursting of the cell.

What does the passivation effect mean for this battery?

After prolonged 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 brief voltage delay. This should be considered in the circuit design for applications that require current immediately after activation.
