2. Safety Information
Lithium batteries require careful handling. Failure to follow these safety guidelines can result in fire, explosion, or personal injury.
- Do not recharge: These batteries are non-rechargeable. Attempting to recharge them may cause leakage, fire, or explosion.
- Do not short-circuit: Avoid connecting the positive and negative terminals directly. This can cause excessive heat, fire, or explosion.
- Do not expose to high temperatures: Keep batteries away from heat sources, direct sunlight, and do not incinerate. High temperatures can cause leakage or explosion.
- Do not disassemble or modify: Tampering with the battery can lead to internal short circuits, leakage, or explosion.
- Keep out of reach of children: Store batteries in a safe place to prevent accidental ingestion or misuse.
- Proper disposal: Dispose of used batteries according to local regulations. Do not dispose of with household waste.
- Avoid contact with skin/eyes: In case of leakage, avoid contact with battery fluid. If contact occurs, rinse immediately with water and seek medical attention.

4. Setup and Installation
This battery is intended for use as a replacement or new installation in compatible Allen Bradley PLC systems. Always refer to your specific PLC's instruction manual for detailed battery replacement procedures and safety precautions.
General Installation Steps:
- Power Down: Before attempting any battery replacement, ensure the PLC system is completely powered down and disconnected from all power sources to prevent electrical shock or damage to the PLC.
- Locate Battery Compartment: Identify the battery compartment or location on your specific Allen Bradley PLC model. This is often clearly marked.
- Remove Old Battery (if applicable): Carefully disconnect the old battery's connector from the PLC board. Note the orientation of the connector.
- Insert New Battery: Connect the new ele ELEOPTION PLC Lithium Battery to the designated port on the PLC board. Ensure the connector is fully seated and correctly oriented (red wire typically positive, black wire negative).
- Secure Battery: Place the battery securely within its compartment or mounting area, ensuring it does not interfere with other components.
- Power Up: Once the new battery is installed, re-connect power to the PLC system and power it on. Verify that any battery warning indicators are off.
- Dispose of Old Battery: Dispose of the old battery responsibly according to local environmental regulations.
Warning: Incorrect polarity or improper installation can damage the PLC or the battery. Always double-check connections.
5. Operating Instructions
Once correctly installed, the ele ELEOPTION PLC Lithium Battery operates automatically, providing continuous backup power to maintain PLC memory and real-time clock functions during power outages or when the PLC is powered down. As a non-rechargeable battery, no user intervention is required for its operation beyond initial installation.
- Monitoring: Regularly check your PLC's status indicators for any low battery warnings. The lifespan of the battery will vary depending on the PLC model and usage conditions.
- Replacement: Replace the battery promptly when a low battery warning is indicated by the PLC to prevent data loss.
6. Maintenance
These lithium batteries require minimal maintenance. Adhering to the following guidelines will help ensure their longevity and safe operation:
- Storage: Store unused batteries in a cool, dry place, away from direct sunlight and extreme temperatures. Keep them in their original packaging until ready for use to prevent accidental short-circuiting.
- Inspection: Periodically inspect installed batteries for any signs of physical damage, leakage, or corrosion. Replace immediately if any issues are observed.
- Cleaning: If necessary, gently clean the battery's exterior with a dry cloth. Do not use liquids or abrasive cleaners.
- Disposal: Never dispose of lithium batteries in regular household trash. They contain materials that can be harmful to the environment. Always follow local regulations for battery recycling or hazardous waste disposal.
7. Troubleshooting
If you encounter issues after installing the battery, consider the following troubleshooting steps:
- PLC Battery Warning Light Remains On:
- Ensure the battery connector is fully and correctly seated in the PLC port.
- Verify the battery's polarity is correct.
- Check if the battery itself is faulty. Try a new battery from the pack.
- Consult your PLC's manual for specific battery warning reset procedures.
- PLC Does Not Retain Memory After Power Cycle:
- This indicates the battery is not providing backup power. Re-check installation as described above.
- Ensure the battery is not depleted. Replace with a new battery if necessary.
- Verify the PLC's battery circuit is functioning correctly (refer to PLC manual).
If problems persist after following these steps, contact the PLC manufacturer's technical support or a qualified technician.
