803040 LiPo battery: 3.7 V, 1000 mAh, for GPS and portable devices
One listing, stated exactly: 3.7 V, 1000 mAh, 8.0 x 30 x 40 mm, with the certificate set, minimum order, enquiry price range and lead time shown below belonging to this listing alone.

This is the 1000 mAh listing of the 803040, and the distinction matters because the same model number appears in other listings with different capacities and terms. One other listing states 450 mAh with a different certificate set, price range and lead time; another states 1000 mAh without the size and certificate detail shown here. A buyer who orders an 803040 without naming the capacity and the listing will quite possibly receive the wrong record's terms, so this page exists to pin the conversation to one listing: 3.7 V, 1000 mAh, 8.0 x 30 x 40 mm, with UL, KC, CE and RoHS markings plus MSDS documentation as listed.
At 1000 mAh in an 8.0 x 30 x 40 mm outline, this cell suits compact portable devices where the cavity is roughly credit-card sized in footprint and 8 mm thick. GPS trackers are the named anchor application, and the size-to-capacity balance fits that use: a tracker needs enough energy for days of standby with periodic transmission, in a housing that must stay small enough to mount discreetly. MP4 players, small digital products and portable electronic devices share the same shape constraint, which is why they appear alongside GPS in the listing's application list.

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.
The certificate set on this listing — UL, KC, CE and RoHS, with MSDS — should be confirmed for the destination market before ordering, because a certificate set that satisfies one market may not satisfy another, and certificates are available upon request for this exact model. Ask for the documents by model number and capacity, and confirm that the set you receive matches the listing rather than a neighbouring listing's set. That check costs one message and prevents a compliance surprise at import.
Commercially, this listing is unusually accessible: a minimum order of 1 piece, an enquiry range of $1.10–1.50 and a 7-day lead time, all for this listing only. Those terms make sampling straightforward, but they do not transfer to other 803040 listings or to other models, and the enquiry range is a listed range, not a confirmed transaction price. Confirm the price, lead time, payment terms and warranty in writing for this listing before payment, and confirm whether the supply is from stock or made to order, since that distinction changes the real lead time.
For a GPS tracker inquiry based on this cell, state the tracker's cavity dimensions against the 8.0 x 30 x 40 mm outline, the tracker's average and peak currents, the reporting interval and the operating environment. With those facts, the runtime question becomes a calculation and the fit question becomes a measurement, and the supplier can confirm whether this listing — rather than a larger or smaller cell — is the right starting point for samples.

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.
