Powerful in a wide range of applications

The Tadiran SL-761PT has been specifically developed for long-term applications with low continuous current, where the battery is permanently integrated into the electronics. The axial wires allow flexible and direct integration into the circuit. Its primary areas of application include memory backups (RTC, CMOS) in industrial controllers (PLC), metering technology (metering for water, gas, electricity) as well as long-life security technology and alarm systems. It is the perfect choice for all devices that need to operate autonomously for a decade or more without a battery change.

Designed for maximum safety and efficiency

The safety and longevity of the SL-761PT are based on the proven Tadiran construction. The cell features a hermetic glass-to-metal seal that reliably prevents the electrolyte from leaking. The inorganic electrolyte used is non-flammable and ensures a high level of intrinsic safety. Each cell is designed to deliver its energy constantly 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 power 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 storage and operating life. This ensures that the energy is still reliably available even after many years.

FAQs about this Tadiran battery

What does the "axial wires" connection mean?

This model is equipped with connection wires that exit the centre of the positive and negative poles of the cell and run in opposite directions along the longitudinal axis. This configuration enables very flexible mounting and direct, fixed connection to the electronics by soldering, without requiring a battery holder.

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

The SL-700 series is optimised for the absolute lowest self-discharge. It is the best choice for applications that require very little power over many years, such as memory backup in computers. 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 type of battery is ideal for professional electronics where the battery is permanently soldered and an extremely long service life is crucial. Typical applications are meters, industrial computers, alarm systems and long-life sensors.

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 can lead to overheating, leakage or bursting of the cell.

What does the passivation effect mean with this battery?

After extended storage, a protective layer forms on the lithium surface. This layer is the reason for the extremely low self-discharge. On first load, it can lead to a short voltage delay. This should be considered in circuit design for applications that require immediate current after activation.
