8. Dispose of the old battery properly. Take it to a recycling center or follow local hazardous waste rules.

Tip: Replace your battery every 1-2 years, even if you do not use your watch often. This prevents leaks and keeps your device safe.

Safe Handling Tips

You must handle the battery with care during replacement. Follow these tips to keep yourself and your device safe:

• Always keep batteries away from children and pets. These small batteries can be swallowed and cause serious harm.
• Use child-resistant packaging and read all safety warnings before starting the replacement.
• Never touch both sides of the battery with metal tools. This can cause a short circuit.
• Avoid damaging waterproof seals when opening the watch. Moisture can enter and harm the internal parts.
• Use only the correct battery type and size for your device. Wrong batteries may cause malfunction or damage.
• Work in a clean, well-lit area. This helps you see small parts and prevents mistakes.
• If you cannot remove the battery safely, ask a professional for help.

Storage & Disposal

Storage Best Practices

You can make your SR626SW batteries last longer by following a few simple storage tips. Proper storage protects the battery’s chemical stability and keeps your devices running when you need them. Here are the best ways to store your watch batteries:

1. Store batteries in a cool, dry place away from direct sunlight. Heat and moisture can shorten battery life and cause leaks.
2. Keep batteries in their original packaging until you need them. The packaging shields them from humidity and dust.
3. Turn off devices when not in use. If you do not use a device often, remove the battery to prevent unnecessary power drain.
4. Clean battery contacts regularly. This prevents corrosion and helps the battery deliver power efficiently.
5. Do not mix old and new batteries or different types in the same device. Mixing can cause leaks or poor performance.
6. Make sure water-resistant watches have tightly sealed battery compartments. This keeps moisture out and protects the battery.
7. Keep batteries away from strong magnets. Magnetic fields can interfere with battery performance.

Tip: The ideal storage temperature for SR626SW batteries is about 68°F (20°C). For every 18°F (10°C) increase, the battery’s self-discharge rate nearly doubles.

Storing batteries correctly helps prevent corrosion and extends shelf life. Using sealed packaging with silica gel can also reduce the impact of humidity.

Proper Disposal

You should never throw SR626SW batteries in the trash. These batteries contain metals that can harm the environment if not handled properly. Responsible disposal keeps your community and the planet safe. Here’s how you can dispose of your used watch batteries:

• Take used batteries to a local recycling center or a retailer that offers battery recycling programs. Many stores accept small batteries for recycling.
• Use websites like Call2Recycle to find recycling locations near you.
• Recycling centers use special processes to recover valuable metals like silver. They separate battery parts and treat hazardous waste safely.
• After recycling, any leftover waste goes to special landfills designed for hazardous materials.

Note: Proper recycling prevents toxic materials from entering soil and water. Always follow local guidelines for battery disposal.
