Features

· High Voltage

Nominal voltage of 3.6V, among the highest in primary lithium batteries
· Extremely High Energy Density

Both gravimetric and volumetric energy density are outstanding — ideal for ultra-long-term applications
· Ultra-Long Lifespan

Operating life can exceed 10–15 years, perfect for smart meters and remote sensors
· Low Self-Discharge

Typically less than 1% per year, making it ideal for long-term storage and low-duty-cycle devices
· Wide Operating Temperature

Standard range -40°C to +85°C, with high-temperature versions reaching +150°C.
· Primary Cell (Non-Rechargeable)

Designed for one-time, long-duration use; not suitable for recharging
· Industrial-Oriented

Commonly used in utility metering, tracking devices, remote monitoring systems, military electronics, etc.
· High Internal Resistance

Best suited for low continuous current applications; for high pulse needs, pairing with capacitors is recommended
