Saft Lithium Thionyl Chloride 3.6V, A Battery

The Saft 3600mAh lithium-ion A size battery is hermetically sealed in stainless steel cans and has a nominal voltage of 3.6V. This battery is suitable for long-term applications, typically for 5 to 20 years. It usually features low base current and periodic pulses.
Note:
Due to the high terminal voltage of 3.6V, they are not suitable as direct replacements for other battery technologies in the same can sizes.
