2. Safety Information

Please read and understand all safety precautions before handling or installing batteries. Failure to follow these instructions may result in fire, explosion, leakage, or other hazards.

• Keep out of reach of children: Button cell batteries can be swallowed. If swallowed, seek immediate medical attention.
• Do not recharge: These batteries are not rechargeable. Attempting to recharge may cause leakage or explosion.
• Do not disassemble or modify: Tampering with batteries can lead to internal short circuits, leakage, or explosion.
• Do not expose to heat: Avoid direct sunlight, high temperatures, or fire. This can cause leakage, explosion, or fire.
• Do not short-circuit: Keep batteries away from metal objects that could cause a short circuit.
• Observe polarity: Always insert batteries with the correct positive (+) and negative (-) orientation as indicated by the device.
• Avoid contact with skin and eyes: If battery fluid comes into contact with skin or eyes, immediately flush with plenty of water and seek medical attention.

3. Installation

Installing a watch battery typically requires specific tools and careful handling. If you are unsure, it is recommended to consult a professional watch repair technician.

1. Prepare your workspace: Work on a clean, well-lit surface. Use a soft cloth or mat to prevent scratching your watch.
2. Open the watch case: Depending on your watch model, this may involve unscrewing a case back, prying it open with a case knife, or using a specialized tool.
3. Remove the old battery: Carefully note the orientation of the old battery. Use non-metallic tweezers or a small screwdriver to gently lift and remove it. Avoid touching the watch movement with bare hands.
4. Insert the new battery: Place the Murata SR626W battery into the battery compartment, ensuring the correct polarity (usually positive side up). Use non-metallic tweezers to avoid scratching the battery or watch components.
5. Secure the battery: Ensure the battery is seated correctly and any retaining clips are re-engaged.
6. Close the watch case: Carefully re-attach the watch case back, ensuring a secure fit to maintain water resistance (if applicable).
