Powerful in diverse applications

The Tadiran SL-361T was specifically developed for applications where both miniaturisation and improved power output are critical. The solder tabs enable a reliable and permanent integration into the circuit. Its primary fields of application include compact wireless sensors, miniaturised GPS trackers, medical monitoring devices, and other professional electronics that require regular transmission pulses in the smallest of spaces.

Engineered for maximum safety and efficiency

The safety and longevity of the SL-361T are based on the proven Tadiran design. The cell features a hermetic glass-to-metal seal that reliably prevents the electrolyte from leaking. The inorganic electrolyte used is non-flammable and provides 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.

iXtra series: The technology for higher performance

The Tadiran iXtra series 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 shows better behaviour under moderate load demands and pulse currents. The passivation effect is thus overcome more quickly, resulting in a more stable energy supply in applications that regularly "wake up" to perform tasks.

FAQs about this Tadiran battery

What does the connection with solder tabs mean?

This model is equipped with metal contacts known as solder tabs, which can be soldered directly onto a printed circuit board (PCB) for easy and permanently secure fastening. This ensures excellent mechanical and electrical connection without the need for a battery holder.

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

The SL-300 (iXtra) series, to which this cell belongs, 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 very low 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, where the battery is permanently soldered and long service life with regular current demand is crucial. Examples are 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 charge the cell is dangerous and can result in overheating, leakage or bursting of the cell.

What does the passivation effect mean for this battery?

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