Panasonic 6V Battery, BR-2/3AGCT4A

Product Description

• Nominal Voltage: 6.0 V  
• Nominal Capacity: Typically ranges from 2400 mAh to 4400 mAh depending on the specific source and manufacturer/supplier. Some sources list 2400mAh, while others, particularly those selling replacements, might state higher capacities like 4400 mAh or even 5800 mAh. It’s crucial to verify the capacity with the specific supplier.
• Chemistry: Lithium Thionyl Chloride (Li-SOCl2) – This is the chemistry of the individual cells (BR-2/3AG). The pack configuration maintains this chemistry benefit.
• Non-Rechargeable: This is a primary (single-use) lithium battery pack and cannot be recharged.
• Self-Discharge Rate: Low, typically allowing for a long shelf life (often quoted as up to 10 years under proper storage conditions).

Physical Characteristics:

• Cell Size: Each individual cell is a 2/3A size.
• Number of Cells: 4 cells connected in series.  
• Dimensions: The overall dimensions of the pack can vary slightly depending on the connector and packaging, but are generally around:
  • Length: Approximately 41.2 mm to 45.7 mm
  • Width: Approximately 33 mm to 35.1 mm
  • Height: Approximately 33 mm to 33.8 mm  
  • Individual cell diameter is around 17 mm and height around 33.5 mm.
• Weight: Approximately 55 g to 100 g (again, varies slightly).
• Connector: Typically features a 2-pin connector, often a black or brown JAE connector. The specific type (e.g., with or without a hook) can vary, so visual confirmation with your application is important.

Operating Characteristics:

• Operating Temperature Range: Wide, typically -40°C to +85°C (-40°F to +185°F), making it suitable for industrial environments.  
• Maximum Discharge Current: Varies depending on the cell and pack configuration. For the individual BR-2/3AG cell, the continuous standard drain is around 2.5 mA. The maximum pulse discharge current for the pack will be higher but is not consistently specified across sources.

Key Applications:

• Backup power for PLCs (Programmable Logic Controllers)
• Memory backup for CNC (Computer Numerical Control) systems
• Powering industrial computers and controllers
• Measuring instruments
• Alarm systems
• Robotics and automation equipment

Important Notes:

• Connector Type: Always verify the connector type (color, pins, and any additional features like a hook) matches your equipment’s requirements.
• Capacity Variations: Be aware that replacement batteries might advertise slightly different capacities. Choose a reputable supplier.
• Non-Rechargeable: Do not attempt to recharge this battery pack as it could be dangerous.
