3. Safety Information and Cautions
To ensure safe operation and prevent damage, please observe the following safety guidelines:
- Keep away from children: Button cell batteries can be swallowed and pose a choking hazard or cause severe internal burns. Store batteries out of reach of children.
- Do not recharge: These batteries are not rechargeable. Attempting to recharge them may lead to leakage, fire, or explosion.
- Do not dispose of in fire: Batteries may explode or leak if disposed of in fire.
- Avoid short circuits: Do not allow the positive (+) and negative (-) terminals to come into contact with each other or with metal objects. This can cause the battery to overheat, leak, or explode.
- Proper handling: When handling batteries, avoid touching both terminals simultaneously with your fingers, as the human body is conductive and can cause a slight discharge, reducing battery life.
- Do not disassemble: Do not attempt to open or disassemble the battery.
- Leakage: If battery leakage occurs, avoid contact with skin and eyes. If contact occurs, rinse immediately with plenty of water and seek medical attention.

4. Installation and Usage
Follow these steps to install and use your LiCB SR626SW battery:
- Identify Battery Type: Confirm that your device requires an SR626SW or compatible battery (e.g., 377, 626, AG4).
- Open Battery Compartment: Carefully open the battery compartment of your electronic device. This often requires a small screwdriver or a specific tool for watches.
- Remove Old Battery (if applicable): If replacing an old battery, note its orientation (positive/negative terminals) before removal. Dispose of old batteries responsibly.
- Clean Contacts: Gently clean the battery contacts in the device with a dry cloth or cotton swab to ensure good conductivity.
- Insert New Battery: Insert the new LiCB SR626SW battery, ensuring the positive (+) side aligns with the positive indicator in the compartment and the negative (-) side aligns with the negative indicator. The positive side is typically marked with a plus sign or the battery model number.
- Close Compartment: Securely close the battery compartment.
- Test Device: Power on your device to confirm proper installation and functionality.
These batteries are suitable for a wide range of small electronics. For specific device instructions, refer to your device's user manual.
5. Storage and Maintenance
Proper storage and maintenance will help preserve battery life and ensure safety:
- Storage Conditions: Store unused batteries in their original packaging in a cool, dry place, away from direct sunlight and extreme temperatures.
- Avoid Metal Contact: Do not store batteries loosely or with metal objects (e.g., coins, keys) that could cause a short circuit.
- Shelf Life: LiCB SR626SW batteries have a shelf life of 3 years when stored correctly.
- Disposal: Dispose of used batteries according to local regulations. Many communities have recycling programs for batteries. Do not throw them in household trash.
6. Troubleshooting
If your device does not function after battery installation, consider the following:
- Check Polarity: Ensure the battery is inserted with the correct positive (+) and negative (-) orientation.
- Verify Battery Type: Confirm that the SR626SW is the correct battery type for your device.
- Clean Contacts: Ensure battery and device contacts are clean and free of debris or corrosion.
- Test Battery: If possible, test the battery voltage with a multimeter to ensure it has a full charge.
- Device Malfunction: If the battery is confirmed to be good and correctly installed, the issue may lie with the device itself.
