Maxell SR626SW Battery
Maxell manufactures SR626SW silver-oxide watch batteries that are compatible with the standard 6.8×2.6mm specification. This page covers specifications, quality, and where to find Maxell SR626SW batteries.
When choosing a replacement battery, brand reputation matters. Maxell has established itself in the market with consistent quality and reliable performance. Their SR626SW is used by consumers and professionals worldwide for quartz watches, calculators, and other precision devices. This page provides the details you need to make an informed purchase.
Specifications
The Maxell SR626SW meets standard dimensions: 6.8mm diameter × 2.6mm height. Nominal voltage is 1.55V, with capacity typically 25–28 mAh. Silver-oxide chemistry provides stable voltage for accurate timekeeping.
The battery operates within a temperature range of approximately -10°C to +60°C, suitable for normal wear. Shelf life is typically 5–10 years when stored in cool, dry conditions. Always check the expiration date printed on the package before use.
Quality and Compatibility
Maxell SR626SW batteries are suitable for quartz watches, calculators, and other small devices that specify 377, AG4, or SR626SW. They are interchangeable with other silver-oxide equivalents.
Whether your device calls for SR626SW, 377, or AG4 silver-oxide, the Maxell version will work. The key is ensuring you purchase the silver-oxide variant, not alkaline. The package should clearly state the chemistry. If you are unsure about compatibility, check our equivalent batteries page.
Typical Runtime and Performance
In a typical quartz watch, the Maxell SR626SW should last 1–3 years depending on the watch's power consumption. Simple analog watches often achieve 2–3 years. Watches with backlights, alarms, or chronograph functions may drain the battery faster. Temperature extremes can also affect runtime.
Silver-oxide batteries maintain stable voltage throughout their life, which helps preserve timekeeping accuracy. As the battery nears end of life, the voltage drops quickly—you will get a clear signal when replacement is needed, often before the watch stops completely.
Where to Buy
Look for Maxell SR626SW at electronics retailers, hardware stores, and online marketplaces. Always verify the package indicates silver-oxide and check the expiration date.
Buy from authorized sellers when possible to avoid counterfeits. Compare prices across retailers—multi-packs often offer better value if you have several devices. Check that the packaging is sealed and shows the correct model number.

Devices That Use SR626SW
The Maxell SR626SW powers quartz wristwatches, pocket watches, calculators, digital thermometers, laser pointers, small LED lights, electronic toys, glucose meters, and various medical devices. Any device that specifies SR626SW, 377, or AG4 silver-oxide will work with this battery.
Runtime depends on the device. A simple analog watch may run 2–3 years. A calculator with frequent use may need replacement sooner. Temperature extremes can affect performance. Store spare batteries properly to maintain shelf life until needed.
Shelf Life and Storage Tips
Silver-oxide batteries like the Maxell SR626SW typically have a shelf life of 5–10 years when stored correctly. Keep them in a cool, dry place away from direct sunlight. Avoid storing in bathrooms or cars where humidity and temperature fluctuate.
Do not store batteries loose with metal objects—contact between terminals can cause discharge. Keep in original packaging until use. Check the expiration date before installing. Batteries past their date may have reduced capacity. Multi-packs are convenient; ensure you will use them within the shelf life.
Brand-Specific Considerations
Different brands may have slight variations in packaging, expiration dating, and availability. Japanese brands (Maxell, Sony, Seizaiken) are often favored for their consistency. Choose based on availability in your region and your budget.
Multi-packs are convenient if you have several devices. They often offer better value per battery. Ensure proper storage: cool, dry, and away from metal. Check expiration dates before use—fresh batteries perform best.
Quality Assurance and Testing
Reputable manufacturers test each batch for voltage, capacity, and leakage. Maxell follows industry standards for silver-oxide production. The result is consistent performance across individual cells. When you buy a Maxell SR626SW, you can expect it to meet the specifications printed on the package.
Counterfeit batteries are a concern in the market. To avoid fakes, buy from authorized retailers or the brand's official channels. Genuine packaging should be sealed, show clear labeling, and include an expiration date. If the price seems unusually low, verify the seller's reputation.
When to Choose Maxell
Choose Maxell when you want a reliable replacement from a recognized brand. Whether for a daily-wear watch, a backup for travel, or a bulk purchase for multiple devices, Maxell SR626SW delivers consistent performance. The brand is widely available, making it easy to find when you need a replacement.
Compare prices across retailers—online and in-store. Some retailers offer multi-packs that reduce the per-battery cost. If you have several watches or devices that use SR626SW, buying in bulk can save money. Just ensure proper storage to maintain shelf life until needed.
