High-temperature Lithium thionyl chloride (LiSOCl2) batteries are typically designed to operate within a temperature range of -55°C to +150°C (-67°F to +302°F). However, the specific working temperature range for a LiSOCl2 battery depends on the manufacturer and the specific application.

It is important to note that the performance of LiSOCl2 batteries can be affected by the operating temperature. At high temperatures, the self-discharge rate of the battery may increase, leading to a shorter overall lifespan. Conversely, at low temperatures, the battery's output voltage may drop, which could affect the performance of the device being powered.

To ensure optimal performance and longevity of a LiSOCl2 battery, it is essential to follow the manufacturer's recommended temperature range for the specific application.
