Lithium

Lithium photo

Combined high voltage, high energy density, lightweight, long life battery technology.

Main applications: Photographic applications, utility meters and smoke detectors.

Main lithium formats

Available in cylindrical (eg. CR123A) and battery (e.g. 2CR5 and 9V block)

Coin cells

As the name implies, small circular cells and batteries used in many electronic applications.

Main applications: Memory back up, keyless entry fobs, hearing aids,
watches, pagers and small electronic devices.

Technical - Lithium Managanese Dioxide - IEC Code CR

This is the main 3 volt technology. Although more expensive than alkaline it offers the advantages of:

• Higher voltage per cell (3V)
• Longer shelf life
• Good low temperature performance (down to -40C)
• In many instances, better pulse and high rate performance 

The main features are:

• Primary: non-rechargeable
• Nominal voltage 3V
• Maximum open circuit voltage 3.7V
• Energy Density 450 Wh/kg 650 Wh/L
• Temperature range -40°C to 65°C
