Setup and Installation
Replacing the battery in a solar-powered watch requires careful handling and specific tools. If you are not comfortable performing this procedure, it is recommended to seek assistance from a qualified watch technician.
Required Tools:
- Small Phillips head screwdriver
- Watch case opener (for screw-back or snap-back cases)
- Non-magnetic tweezers
- Dust blower (optional)
- Clean, lint-free cloth
Installation Steps:
- Prepare Workspace: Work in a clean, well-lit area to prevent dust from entering the watch mechanism.
- Open Watch Case: Carefully open the watch case back using the appropriate tool. For screw-back cases, unscrew the back. For snap-back cases, gently pry open.
- Locate Old Battery: Identify the existing CTL1025 battery. It will typically be held in place by a small metal clamp or clip.
- Remove Old Battery: Using non-magnetic tweezers, carefully unclip or unscrew the retaining mechanism and remove the old battery. Avoid touching other components inside the watch.
- Insert New Battery: Place the new Casio CTL1025 battery (part #10135068) into the battery compartment, ensuring correct polarity (positive (+) side usually faces up). Secure it with the retaining clamp or screw.
- Reset Watch (if applicable): Some Casio watches require a specific AC (All Clear) reset after battery replacement. Consult your watch's specific module manual for details. This often involves shorting a specific contact point to the battery's positive terminal with tweezers.
- Close Watch Case: Carefully replace the watch case back, ensuring a tight seal to maintain water resistance.
- Initial Charge: After installation, expose the watch to bright light (natural sunlight is ideal) for several hours to allow the new battery to receive an initial charge. The watch may not function immediately if the battery is completely drained.
Note: Some watch models, like the Casio GW-1210A (module 3347), may require two CTL1025 batteries. Always verify the number of batteries required for your specific watch model before starting the replacement process.
Operating Your Solar Watch After Battery Replacement
Once the new CTL1025 battery is installed and has received an initial charge, your solar-powered watch should resume normal operation. Solar watches are designed to continuously charge the battery when exposed to light.
Charging Guidelines:
- Regular Light Exposure: For optimal battery life and watch function, ensure your watch is regularly exposed to light.
- Avoid Prolonged Darkness: Storing the watch in complete darkness for extended periods can deplete the battery and may require a full recharge cycle.
- Charging Indicators: Many solar watches have a power reserve indicator. Refer to your watch's specific manual to understand its charging levels and indicators.
Maintenance and Care
Proper maintenance ensures the longevity of your Casio solar watch and its CTL1025 battery.
General Care:
- Keep Clean: Regularly clean the watch case and crystal to ensure the solar panel receives maximum light. Use a soft, dry cloth.
- Avoid Extreme Temperatures: Do not expose the watch to extreme heat or cold, as this can affect battery performance and watch components.
- Water Resistance: If the watch case was opened, ensure the gasket is properly seated and the case back is securely closed to maintain water resistance. It is advisable to have water resistance checked by a professional after battery replacement.
Battery Longevity:
The CTL1025 battery is designed for long-term use. Its lifespan is maximized by consistent exposure to light and avoiding deep discharge cycles.
Troubleshooting
| Problem | Possible Cause | Solution |
|---|---|---|
| Watch does not start after battery replacement. | Battery not charged; incorrect installation; AC reset not performed. | Expose watch to bright light for several hours. Verify battery polarity and secure connection. Perform AC reset if required by your watch model. |
| Watch stops intermittently or power indicator is low. | Insufficient light exposure; battery not fully charged. | Ensure regular and adequate light exposure. Place watch in direct sunlight for a full day to recharge. |
| Watch functions are erratic. | Low battery charge; improper AC reset. | Fully charge the battery. Re-attempt AC reset according to your watch's manual. |
If problems persist after following these troubleshooting steps, contact Casio customer support or a certified watch repair center.
