2. Installation and Setup

Proper installation is crucial for the safe and effective operation of your OmniCel ER14250 battery. This battery comes with pre-attached metal tabs designed for soldering or secure connection within compatible devices. Do not attempt to solder directly to the battery cell itself, as this can cause damage and pose a safety risk.

1. Identify Polarity: Observe the positive (+) and negative (-) markings on the battery and ensure they align with the corresponding terminals in your device. The tabs are also typically marked or configured to indicate polarity.
2. Prepare Connection Points: Ensure the connection points in your device are clean and free from debris or corrosion.
3. Secure Connection: Connect the battery tabs to the device's terminals. If soldering, use appropriate soldering techniques to create a strong, reliable electrical connection. Avoid prolonged heat application to the tabs to prevent heat transfer to the battery cell.
4. Verify Fit: Ensure the battery is securely seated and does not move freely within its compartment.

Note: The metal tabs are an integral part of the battery for specific applications and are not "extra pieces" to be removed. They are designed to facilitate secure electrical connections.

3. Operation

Once properly installed, the OmniCel ER14250 battery will provide a stable 3.6V output to power your device. Lithium Thionyl Chloride batteries are known for their high energy density and consistent voltage discharge throughout their operational life. This battery is designed for continuous low-current discharge with occasional moderate pulses, making it suitable for long-term applications.

• Voltage Stability: The battery maintains a high and stable operating voltage, which is critical for sensitive electronic devices.
• Low Self-Discharge: This battery exhibits a very low self-discharge rate, typically less than 1% per year when stored at +25°C, ensuring that it retains its charge for extended periods when not in use.
• Operating Temperature: The battery is designed to operate effectively across a wide temperature range, typically from -55°C to +85°C. However, extreme temperatures can affect performance and lifespan.

4. Maintenance and Storage

The OmniCel ER14250 battery requires minimal maintenance due to its sealed design and stable chemistry. However, proper handling and storage are essential to maximize its lifespan and ensure safety.

• Storage Conditions: Store batteries in a cool, dry place, ideally at room temperature (around +25°C) and away from direct sunlight or heat sources. The maximum recommended storage temperature is +30°C.
• Avoid Extreme Temperatures: Do not expose the battery to temperatures outside its specified operating range for prolonged periods.
• Keep Dry: Protect the battery from moisture and humidity.
• Inspect Periodically: If stored for long periods, periodically inspect the battery for any signs of damage or leakage.

5. Troubleshooting

If you encounter issues with your OmniCel ER14250 battery, consider the following troubleshooting steps:

• Device Not Powering On:
  • Verify correct battery polarity (+ and -) during installation.
  • Check that the battery tabs are securely connected to the device's terminals. Ensure there are no loose connections or poor soldering.
  • Confirm the device itself is functioning correctly with a known good power source, if possible.
• Short Battery Life:
  • Ensure the battery is being used within its specified current limits. High pulse currents beyond the maximum pulse capability (typically 50mA) can reduce effective capacity.
  • Check the operating temperature. Continuous operation at extreme temperatures (especially high temperatures) can shorten battery life.
  • Verify that the device does not have an abnormal current draw or short circuit.
• Physical Damage or Leakage:
  • If the battery shows signs of physical damage, swelling, or leakage, discontinue use immediately. Refer to the Safety Information section for proper disposal.

7. Safety Information and Warnings

Lithium Thionyl Chloride batteries are powerful and require careful handling to prevent injury or damage. Please adhere to the following safety guidelines:

• WARNING: Fire, explosion, and severe burn hazard.
• Do NOT Recharge: This is a primary (non-rechargeable) battery. Attempting to recharge it can lead to overheating, leakage, explosion, or fire.
• Do NOT Crush, Disassemble, or Incinerate: Physical damage or exposure to fire can cause the battery to rupture, leak, or explode.
• Avoid High Heat: Do not heat the battery above 212°F (100°C). High temperatures can compromise the battery's integrity.
• Avoid Water Exposure: Do not expose the battery or its contents to water.
• Use Tabbed Cells: Do not solder directly to the battery cell. Always use the pre-attached tabs for connections.
• Proper Disposal: Dispose of used batteries according to local regulations. Do not dispose of batteries in household waste or fire. Many communities offer battery recycling programs.
• Keep Out of Reach of Children: Batteries can be a choking hazard and contain hazardous materials.
