VOLTCRAFT 2/3 AA Lithium Battery 3.6 V 1600 mAh Li-SOCl2 Non-Rechargeable (VC-12632305)

Utility metering engineers and security system installers often need a power source that will not quit, even after a decade in the field. The VOLTCRAFT 2/3 AA lithium battery delivers exactly that: a 3.6 V nominal voltage and 1600 mAh capacity in a compact cylindrical cell, built with lithium thionyl chloride (Li-SOCl2) chemistry for exceptional energy density and an ultra-low self-discharge rate of less than 1% per year. Whether you are backing up memory in industrial controllers, powering remote sensors, or ensuring uninterrupted operation of metering equipment, this non-rechargeable primary cell is engineered for long-term reliability in demanding environments.

Key specifications

• Battery type: Lithium Thionyl Chloride (Li-SOCl2)
• Form factor: 2/3 AA (IEC designation ER14335)
• Nominal voltage: 3.6 V
• Capacity: 1600 mAh
• Terminal type: Button top
• Operating temperature range: -55°C to +85°C
• Self-discharge rate: <1% per year
• Shelf life: Up to 10 years
• Rechargeability: Non-rechargeable (primary cell)

Why choose it

This battery is built for longevity. Its lithium thionyl chloride chemistry provides a stable voltage plateau throughout its life, ensuring consistent performance even in extreme temperatures. The non-flammable electrolyte adds a layer of safety, and the high energy density means fewer replacements in hard-to-reach installations. With a shelf life of up to 10 years, you can stock it with confidence for future maintenance needs.

Ideal use cases

• Utility metering (electricity, gas, water)
• Memory backup for industrial controllers and PLCs
• Security systems and alarm sensors
• Remote monitoring and telemetry devices
• Professional electronics requiring reliable long-term power

Good to know

The 2/3 AA size is slightly shorter than a standard AA cell, making it suitable for compact devices. Always observe correct polarity when installing. As a primary lithium cell, it must not be recharged. Dispose of used batteries according to local regulations.
