What are air-alkaline batteries?

Air-alkaline batteries are a special type of primary battery that uses oxygen from the air to generate energy. Because of this technology, they offer a high energy density with relatively low weight.

Advantages of air-alkaline batteries include:

• High energy density
• Low cost
• Environmentally friendly characteristics
• Long shelf life before activation

Once activated by exposure to air, the battery starts discharging immediately and the chemical process cannot be fully stopped.

Air-alkaline batteries are commonly used for:

• Railway signal lighting
• Road signal lighting
• Marine and buoy lighting
• Telecommunications
• Parking meters
• Electric fencing systems
