ER17330V/ Mitsubishi battery 3.6V

Product Description

The Mitsubishi ER17330V battery is a non-rechargeable lithium thionyl chloride (Li-SOCl2) battery widely used in industrial applications, particularly for Programmable Logic Controllers (PLCs), CNC systems, and other automation equipment as a memory backup power source and for real-time clocks. It is known for its high energy density, long lifespan, and reliability.  

Here’s a detailed product information summary:

General Characteristics:

• Manufacturer: Primarily Mitsubishi Electric, but also available from other manufacturers as a compatible replacement (e.g., Toshiba).
• Model Number: ER17330V (also known as A6BAT in some Mitsubishi systems).  
• Type: Non-rechargeable Lithium Thionyl Chloride (Li-SOCl2) battery.  
• Chemistry: Lithium (Li) and Thionyl Chloride (SOCl2). This chemistry provides high voltage and energy density.
• Size: Typically a 2/3A size cylindrical cell.  
• Termination: Often comes with wire leads and a 2-pin connector for easy integration into PLC systems. Some may be available without connectors.  

Electrical Specifications:

• Nominal Voltage: 3.6V  
• Nominal Capacity: Varies slightly depending on the manufacturer, but typically ranges from 1700mAh to 2100mAh (some sources mention up to 4.4Ah, which might be a different variation or a pack). Older versions might have a 2000mAh capacity.
• Maximum Continuous Discharge Current: Typically around 25 mA.
• Pulse Discharge Capability: Can handle pulses up to 120 mA for short durations.
• Self-Discharge Rate: Very low, typically less than 1% per year at 20°C, contributing to its long shelf life (around 8-10 years).  

Physical Specifications:

• Diameter: Approximately 16-17 mm (0.63 – 0.68 inches).  
• Height: Approximately 30-36 mm (1.18 – 1.42 inches).
• Weight: Around 15-25 grams.

Operating and Storage Conditions:

• Operating Temperature Range: Wide, typically from -40°C to +85°C, making it suitable for various industrial environments.  
• Recommended Storage Temperature: Up to +30°C for optimal long-term storage.

Key Features and Benefits:

• High Energy Density: Provides a significant amount of power for its size.
• Long Operating Life: Due to the low self-discharge rate and efficient chemistry.  
• Wide Operating Temperature Range: Suitable for diverse industrial conditions.
• Excellent Reliability: Designed for stable and continuous power supply.
• Maintenance-Free: Non-rechargeable, so no maintenance is required during its service life.
• Stable Voltage: Maintains a consistent voltage output during most of its discharge life.
• Safety Features: Typically glass-sealed positive terminal to prevent leaks and enhance safety (avoid applying shock to this part).  

Typical Applications:

• Programmable Logic Controllers (PLCs): Used as a backup power source to retain memory during power outages (e.g., Mitsubishi FX, A, Q, and AnS series PLCs).
• CNC Systems: Provides backup power for memory and real-time clocks in Computer Numerical Control machines.  
• Industrial Computers: Ensures data retention in case of power loss.  
• Memory Backup: For various electronic devices requiring non-volatile memory.
• Real-Time Clocks (RTCs): Powers RTCs in industrial equipment.
• Measurement and Control Devices: Used in various instruments and meters.
• Automotive Electronics.
• Alarm Systems.
• Robotics.
• Special Electronic Equipment.

Safety Precautions:

• Do not short-circuit or puncture the battery.
• Do not expose to high temperatures or fire.
• Keep out of reach of children.
• Dispose of according to local regulations for lithium batteries.
• Never use this battery with different types or model codes.
• Avoid applying shock or excessive force to the glass-sealed positive terminal.  
• Solder connections should be made carefully to avoid overheating the battery
