Important Note: A new battery will achieve its best performance after 2 or 3 complete cycles of charge and discharge. For this specific Li-MnO2 battery, which is a primary (non-rechargeable) battery, this refers to the initial stabilization period within the device.
4. Operating Instructions
This TrustCell battery is a primary (non-rechargeable) lithium manganese dioxide battery designed to provide stable power to compatible Allen Bradley PLC systems. It is intended for continuous use until its capacity is depleted.
- Non-Rechargeable: This battery is explicitly designed as a primary battery and must not be recharged. Attempting to recharge a non-rechargeable battery can lead to overheating, leakage, or explosion.
- Device Compatibility: Ensure the battery is used only with devices specified in the compatibility list (Allen Bradley 1771-DMC1, 1771-DMC4, 1785-L11B, 1785-L16B, 1785-L20B, 1785-L20BK).
- Power Monitoring: Monitor your device's battery indicator (if available) to determine when replacement is necessary.
- Adapter Charger: If your device uses an external power adapter, avoid using low-quality third-party chargers, as this can negatively impact the device's overall lifespan and potentially the battery's performance.
5. Maintenance and Storage
Proper maintenance and storage can help ensure the longevity and safe operation of your battery.
- Storage Temperature: Store unused batteries in a cool, dry place, ideally between 10°C and 25°C (50°F and 77°F). Do not store above 60°C (140°F).
- Avoid Extreme Conditions: Do not expose the battery to direct sunlight, high humidity, or extreme temperatures (hot or cold).
- Keep Dry: Prevent the battery from coming into contact with water or other liquids.
- Proper Disposal: When the battery reaches the end of its life, dispose of it according to local regulations for lithium batteries. Do not dispose of in household waste or fire.
- Handling: Handle the battery carefully. Avoid dropping it or subjecting it to strong impacts.
6. Troubleshooting
If you encounter issues with your new battery, consider the following troubleshooting steps:
- Device Not Powering On:
- Ensure the battery connector is securely and correctly plugged into the device.
- Verify that the battery is the correct model for your device.
- Check if the device itself has other power-related issues (e.g., power switch, internal fuse).
- Short Battery Life:
- Confirm the battery is genuinely new and not an old stock item.
- Ensure the operating environment temperature is within the recommended range.
- Verify that the device is not drawing excessive power due to a fault.
- Physical Damage:
- If the battery appears swollen, leaking, or damaged, discontinue use immediately and dispose of it safely. Do not attempt to use a damaged battery.
If problems persist after following these steps, please contact customer support for further assistance.
