How to Replace the Watch Battery SR626SW
Replacing a watch battery can be a straightforward process if done correctly. Here’s a step-by-step guide to help you out:
Gather Necessary Tools
Before starting the replacement, gather the following tools:
- Screwdriver (often a flathead or Phillips, depending on your watch)
- Plastic tweezers or a spudger
- A clean cloth
- A new SR626SW battery
Open the Watch Case
Using your screwdriver, carefully remove the screws from the back of the watch. If it is a snap-back case, gently insert a plastic spudger into the seam and pry the back open.
Remove the Old Battery
Take note of how the old battery is positioned before you remove it. Using tweezers, carefully lift the battery out of the watch. Be cautious to avoid touching any other components within the case.
Insert the New SR626SW Battery
Using your plastic tweezers, place the new SR626SW battery in the same position as the old one, ensuring that the positive (+) side is facing up.
Close the Watch Case
Once the new battery is secured, replace the watch case back as it was initially. Ensure it is fixed properly to avoid moisture ingress.
Test the Watch
After replacing the battery, set the time and check to see if the watch is functioning correctly. If it operates smoothly, congratulations! You’ve successfully replaced your SR626SW battery.
Maintenance Tips for Extending Battery Life
To prolong the life of your SR626SW battery and ensure that your watch functions accurately over time, consider the following maintenance tips:
Avoid Exposure to Extreme Temperatures
Extreme heat or cold can significantly affect battery performance. Try to keep your watch away from such conditions to enhance battery longevity.
Store Watches Properly
When not in use, store your watches in a cool, dry place. Avoid damp locations to minimize the risk of corrosion to the battery.
