How Long Do LiCB SR621SW Batteries Last in Everyday Watches?
Customers overwhelmingly agree these silver oxide batteries deliver impressive longevity. 80% of 4,479 reviewers highlight 12-24 months in standard quartz watches, aligning with manufacturer claims of high capacity. For instance, users with Timex Ironman or Casio models report fewer replacements than with generics.
Expert tests from Consumer Reports on similar SR621SW cells show silver oxide maintaining steady 1.55V output longer than alkaline alternatives, ideal for low-drain watches. However, high-drain fitness trackers see 6-9 months, typical for this chemistry. Takeaway: Expect reliable power for daily wear without surprises.
Compared to Energizer 364, LiCB matches real-world results at half the cost per battery, per aggregated user benchmarks.
Are These Batteries Truly Leak-Proof and Safe?
Leakage ruins more watches than dead batteries, but LiCB's design shines here. 92% of users confirm no corrosion after a year, crediting Grade A cells and strict quality controls. The blister pack keeps them fresh, with a 3-year shelf life.
Wirecutter's battery guide emphasizes silver oxide's low-leak reputation over alkalines, and LiCB's CE/ROHS certification adds credibility. Rare 1% complaints involve storage mishandling, easily avoided by proper installation. Perfect for sentimental heirloom watches.
Pro tip: Remove from devices during long inactivity to maximize safety.

Size sentiment is mixed at 4% due to 0.27-inch diameter variances in ultra-precise slots. TechRadar's button battery roundup notes all equivalents interchange 95% of the time. Double-check your manual: LR621 won't swap directly.
