Basically, you’re looking at the battery that keeps a wristwatch ticking for years, and if it’s a cheap quartz model, this is what they’ll want to replace it with—we move these by the pallet to repair shops and online sellers who can’t afford returns.

We usually have stock on these ready to ship, but if you need custom branding or a blister card, figure on 20 days or so from order to dispatch—the MOQ for that is 5,000 pieces, and for teh unbranded OEM version it’s 10,000, which is pretty standerd for this size.

The nominal voltage is 1.5V, which is what you expect, and the lithium manganese dioxide chemistry gives it a shelf life of 10 years at 20°C—that’s better than the old silver oxide cells for long-term storage, and operating range goes from -20°C to +60°C, so it’ll survive a hot car or a cold shiping truck.

One thing that catches people off guard is the capasity—it’s about 45mAh, which sounds low, but for a watch that draws microamps, that’s three to five years of steady use, and we’ve got the SGS and CE certs (the COA comes with the shipment).

Also, the 11.0mm diameter and 3.0mm height are tight tolerances—better than some no-name imports—so if your customer’s watch has a snug compartment, this won’t rattle or short out, though it’s not great for high-drain devices like key fobs or laser pointers, just keep it in watches.

We’ve been handling these for over a decade, and the daily production is north of 1.3 million pieces, so lead time is rarely an issue—free samples are avaliable if you want to test fitment before committing to a run.
For OEM packaging, the MOQ is 10,000 pieces. If you just want your brand on standard packaging, that drops to 5,000 pieces.
Yes, free samples are available. Just cover the shipping cost, and we'll send them out so you can test the fit and performance.
They come with SGS, CE, RoHS, ISO9001, and ISO14001 certifications, so you're covered for quality and environmental standards.
Shelf life is 10 years when stored at 20°C. Keep them in a cool, dry place between -20°C and 45°C for best results.
Absolutely. We offer packaging customization including hang tags, blister cards, and cartons. Just let us know what you need for your retail setup.
