The Tadiran TL-2150/S is a 3.6V lithium thionyl chloride battery that offers excellent reliability and high performance for a wide range of applications. This battery comes with a button top termination style and has a capacity of 1Ah, which is one of the highest nominal capacities on the market today for this size of battery.

The TL-2150/S is a 1/2 AA size battery, with a diameter of 14.5mm (0.57 in) and a height of 25.2mm (0.99 in). It weighs 9.2g (0.32 oz), making it lightweight and easy to carry around.

One of the key advantages of the TL-2150/S is its high operating voltage, which remains stable during most of the application lifetime. This makes it an excellent choice for devices that require a consistent and reliable power source. Additionally, it has an operating temperature range of -60°C to +85°C (-76°F to +185°F), which means it can function in a wide range of environments and conditions.

The TL-2150/S also has a low self-discharge rate, which means it can retain its charge for a long time even when not in use. It has a shelf life of 10+ years and less than 1% capacity loss during storage at ambient temperature before use. This makes it an ideal choice for devices that are not frequently used, such as remote controls, alarms, and other similar applications.

In terms of performance, the TL-2150/S has a maximum recommended continuous current of 50 mA and a maximum pulse current capability of 100 mA. This means it can deliver bursts of power when needed, making it suitable for devices that require intermittent high-power output.

The TL-2150/S is also highly durable, with excellent resistance to humid environments and a low magnetic signature that makes it suitable for use in sensitive electronic devices. Its inorganic (but corrosive) electrolyte makes it non-flammable (and non-pressurized at ambient temperature), adding to its safety and reliability.

In addition to the TL-2150/S, Tadiran offers a range of other high-quality lithium thionyl chloride batteries, including the TL-4902, TL-5101, TL-5902, and TL-5111. Saft also offers comparable batteries, such as the LS-14250 and LS-14250c.
