Powerful in a wide range of applications
The Tadiran SL-350P has been specially developed for applications where both miniaturisation and improved power output are essential. The axial wires allow a secure and vibration-resistant integration without a battery holder. Its primary applications include compact wireless sensors, miniaturised GPS trackers, medical monitoring devices and other professional electronics that require regular transmission pulses in a confined space.
Designed for maximum safety and efficiency
The safety and longevity of the SL-350P 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 ensures a high degree of intrinsic safety. Each cell is designed to deliver its energy consistently and safely over a very long period of time, reducing maintenance costs and lowering the total operating costs of your application.
iXtra Series: The technology for higher performance
The iXtra Series from Tadiran is designed to offer improved voltage stability under load. Compared to the standard series (SL-700), optimised for minimal continuous currents, the SL-300 Series shows better behaviour for medium load demands and pulse currents. The passivation effect is overcome faster, resulting in a more stable power supply in applications that regularly "wake up" to perform tasks.

FAQs about this Tadiran battery
What does the "axial wire" connection mean?
This model is equipped with connection wires that emerge centrally from the positive and negative terminals of the cell and run in opposite directions along the longitudinal axis. This configuration allows very flexible assembly and a direct, firm connection to the electronics by soldering, 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. wireless sensors). It offers more stable voltage under load. The SL-700 series, on the other hand, is designed for absolute long-term use with minimal continuous current, such as pure memory backup applications.
For which applications is this battery type suitable?
This battery type is ideal for miniaturised electronics that require a long service life and where the cell is firmly soldered. Examples include compact wireless sensors, small medical devices and GPS trackers.
Is this battery rechargeable?
No, this is a primary lithium battery and under no circumstances may it be recharged. Attempting to charge the cell is dangerous and may lead to overheating, leakage or bursting of the cell.
What does the passivation effect mean with this battery?
After prolonged storage, a protective layer forms on the lithium surface, minimising self-discharge. The iXtra Series is designed so that this layer is broken down more quickly and with less voltage drop under load than in the SL-700 Series, which is beneficial for applications with regular current pulses.
