1. Scientific Basis for Correct Storage: Storing SR626SW watch batteries in a cool, dry environment is crucial because silver oxide batteries are particularly sensitive to environmental conditions. Temperature significantly affects the self-discharge rate of batteries, and the ideal storage temperature is around 20°C (68°F). For every 10°C (50°F) increase in temperature, the battery's self-discharge rate almost doubles. Additionally, increased humidity can promote surface corrosion and leakage of the electrolyte, not only shortening the battery's own lifespan but also potentially damaging the watch mechanics. Therefore, it’s recommended to use sealed packaging with silica gel desiccants to minimize humidity's impact on the battery.

2. Logic Behind Avoiding Unnecessary Use: Although SR626SW batteries boast a lifespan of several years, unnecessary operation consumes limited energy. Especially for watches with additional functions (such as backlight, alarm, etc.), these features continue to drain the battery even when not on the wrist. Hence, if the watch will not be used for an extended period, it's advisable to stop it or remove the battery, which can extend the battery's static storage life by reducing the progression of chemical reactions.

3. Importance of Regular Maintenance: Optimizing battery performance is not just about the battery itself but also involves the overall condition of the watch. Corrosion or contamination of the battery contact points can hinder effective current flow, reducing watch performance and increasing the battery load. Professional watchmakers can clean these contact points and check for damage or poor sealing in the battery chamber, key factors affecting battery performance and lifespan.

4. In-depth Analysis of Magnetic Field Impact: The effect of strong magnetic fields on watch batteries is mainly indirect, by magnetizing the watch's metal parts, especially the timekeeping mechanical components, thereby affecting the watch's accuracy. Long-term or repeated exposure to magnetic fields can lead to mechanical failure of the watch, indirectly increasing the battery load. Thus, keeping the watch away from high magnetic fields is a dual safeguard for protecting both the battery and the watch's mechanical components.

5. Correct Understanding of Waterproof Performance: For waterproof watches, maintaining the seal of the battery compartment is key to preventing moisture ingress. Water entering the battery chamber can not only cause short circuits but also corrode battery contact points and internal watch mechanics, causing irreversible damage. Therefore, after each battery replacement, ensure the battery cover is resealed and have a professional check the watch's waterproof performance, especially after exposure to underwater activities.
