LS26500 (C format) Li-SOCl2 primary lithium batteries are designed specifically for long-term (3- to 20-year) applications, optimized for base currents of a few µA with periodic pulses in the 5–150mA range.

Saft primary lithium batteries feature a high operating voltage, stable over the specified application lifetime, along with some of the highest nominal capacities on the market. They offer an operating temperature range of -60°C to +85°C, and provide exceptional shelf and standby life thanks to a low self discharge rate of less than one percent per year (at +20°C). They also provide excellent resistance to humid environments, and a low magnetic signature.
