Tadiran SL-350 Lithium battery 1/2 AA with 3.6 V and 1.2 Ah
Description
Product information
The Tadiran SL-350 from the iXtra series is a primary lithium-thionyl chloride battery in the extremely compact 1/2 AA size. It was developed especially for miniaturised applications that require a long service life in combination with a moderate current carrying capacity. With a nominal voltage of 3.6 V and a high capacity of 1.2 Ah, it is the ideal energy solution for professional electronics that require regular moderate current pulses in the smallest space.
Highlights at a glance
- Compact and powerful: Optimised for moderate loads in the miniaturised 1/2 AA size.
- High capacity: 1.2 Ah for long runtimes in small devices.
- High rated voltage: Stable voltage of 3.6 V for almost the entire lifetime.
- Maximum reliability: Proven long-term stability and low self-discharge.
- Wide temperature range: Reliable operation from -55 °C to +85 °C.
Powerful in a wide range of applications
The Tadiran SL-350 was specifically developed for applications where both miniaturisation and improved power output are crucial. 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 space. It is the perfect choice for all devices that need to function autonomously for years and periodically require power for transmission or measurement operations.
Engineered for maximum safety and efficiency
The safety and lifespan of the SL-350 are based on proven Tadiran engineering. 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, minimising maintenance costs and reducing the total cost of ownership of your application.
iXtra series: Technology for higher performance
The iXtra series from Tadiran is designed to provide improved voltage stability under load. Compared to the standard series (SL-700), which is optimised for the lowest continuous currents, the SL-300 series shows better performance with medium load requirements and pulse currents. The passivation effect is overcome faster, resulting in more stable power supply in applications that regularly "wake up" to perform tasks.

FAQs about this Tadiran battery
What is the difference between the SL-300 (iXtra) and the SL-700 series?
The SL-300 (iXtra) series, which this cell belongs to, is optimised for applications with moderate current demands (e.g. wireless sensors). It provides more stable voltage under load. The SL-700 series, on the other hand, is designed for absolute long-term use with minimal continuous current, as in 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 but regularly need power for functions such as sending data. Examples are compact wireless sensors, small medical devices and GPS trackers.
Does this model have solder lugs or wires?
No, the SL-350 model described here (as standard version SL-350S) has standard battery contacts and is intended for use in a suitable 1/2 AA battery holder. For direct installation, Tadiran also offers variants of this cell type with different solder lugs.
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 lead to overheating, leakage, or the cell bursting.
What does the passivation effect mean for this battery?
After prolonged storage, a protective layer forms on the lithium surface, which minimises self-discharge. The iXtra series is engineered so that this layer is broken down more rapidly and with lower voltage drop under load than with the SL-700 series, which is beneficial for applications with regular current pulses.

At the latest, if the light no longer passes the annual endurance test for the full emergency lighting period, the battery must be replaced immediately. The typical lifespan of a NiMH battery in this application is approximately 4 years.Why is it important to use the exactly matching plug?The JST plug is a widely used standard in electronics. Using the appropriate pre-assembled plug ensures a polarity-safe and electrically flawless connection to the luminaire electronics. DIY solutions using screw terminals or adhesive tape are not permitted in safety-relevant systems.Can I replace this battery with one with a higher capacity (mAh)?As a rule, this is possible as long as the voltage (4.8V), technology (NiMH) and design are identical. A higher capacity will result in a longer emergency lighting period. However, you must ensure that the battery physically fits into the luminaire housing.How should this battery be disposed of?Batteries must not be disposed of with household waste. As a used device battery, you can return it free of charge at collection points in retail or at municipal recycling centres (e.g. via the GRS collection boxes) to ensure professional and environmentally friendly recycling.
