Wearable bands curve, and the 150732 curves with them. At 1.5 x 7 x 32 mm, it is a small, slim curved cell designed to sit along a band or bracelet where a flat cell would leave dead space and press unevenly. The capacity is correspondingly small — 20 mAh — and this page is explicit about that trade: the curved shape buys fit and comfort, and it pays for them in energy. A wearable that needs days of runtime from a single charge will not get them from 20 mAh, and a wearable that sips power between brief active periods may find 20 mAh entirely adequate.
The listing's cycle life is stated as 300 times. For a wearable charged daily, that figure translates into roughly a year of daily cycling before capacity falls to the listing's end-of-life level, though real life depends on charge habits, temperature and depth of discharge. A wearable maker should plan for that horizon: either design for a replaceable cell, or accept a service-life limit, or choose a larger cell if the band allows it. The 300-times figure belongs to this listing and should not be quoted for other curved cells, which carry their own figures where stated.

Blank fields in the source listing are left blank here; no default value has been filled in. Prices on the company website are listed enquiry ranges for this listing, not confirmed transaction prices.
Commercially, this listing states a 10-piece minimum order, an enquiry range of $1.60–1.88 and a 7-work-day lead time, all for this listing only. That small minimum suits a fit test in the real band: confirm the curve radius against the band, confirm the cell sits without stress on the pouch, and measure runtime in the real device before committing to a band design around this cell. The listing's application field names toys and consumer electronics, while its title names wearables; this page treats the wearable use as the anchor, following the title, and does not extend the cell to applications the listing does not name.
The other curved listings differ substantially: the 302040 is a 200 mAh curved cell for wearables, and the 651458 is a 500 mAh curved cell listed for smart bracelets among other uses. A buyer choosing between curved cells should compare them on band geometry and runtime target, not on the shared word curved. If none of the three matches the band's radius and length, the custom route — custom curved shapes are part of the factory profile's custom capability — starts from the band drawing.
For an inquiry based on this cell, state the band's radius and available length, the device's average current and runtime target, the charging arrangement, and whether the cell must be replaceable. Those facts, with the 1.5 x 7 x 32 mm outline, are enough for the supplier to confirm fit and to say whether sampling this listing or designing a custom curve is the right next step.

How to place an inquiry, step by step
- Send the device facts. Tell us the device type, the available space (length, width and maximum thickness), the nominal voltage you need, the capacity or runtime you target, and the peak current if your device has motors, radios or heaters.
- Name the model or the shape. If a page on this site matches, quote its model number and listing details. If nothing matches, say so and describe the shape — flat, round, curved or ultra-thin — so the conversation starts on the custom route.
- Confirm documents and terms in writing. Ask for the certificate set for that exact model, confirm the minimum order, the listed enquiry price range and the lead time for that listing, and confirm payment and warranty terms before you pay. Terms stated for one model listing do not transfer to another model.
- Agree the sample step. Confirm whether the next step is a listed sample, an engineering sample for a custom shape, or a small trial order, and what test you will run on arrival — fit in the enclosure, runtime, or peak-current behaviour.
Send all of this in one message through the contact page: device type, space, voltage, capacity, peak current, model number if you have one, and the documents you need. That is the whole inquiry — one message, no account, no extra step.
What to send us now
Send one message with your device type, the space the battery must fit, the voltage and capacity you need, the peak current if it matters, and the model number if a page on this site already matches. Add the documents you need — certificates available upon request — and whether you need a listed model or a custom shape. Use the contact page and address it to the sales team by first name as published there. A specific message like that is what turns a catalogue of hundreds of models into a short, answerable question.
