Rechargeable Battery Manufacturer in Shenzhen

Rechargeable batteries, chargers and fans from a Shenzhen manufacturer

Shenzhen Doublepow Energy Technology Co., Ltd. describes itself as a company working in the research and development, manufacture, sales and service of rechargeable batteries, battery chargers and consumer electronics. The company profile states that the company was founded in 2012 and is based in Shenzhen, Guangdong, near Hong Kong. Those two sentences carry the whole opening claim of this site, and both are attributed to the company profile rather than presented as independently verified facts. Everything after this paragraph is organised to help a trade buyer move from that opening statement to a shortlist, and then to an enquiry that asks the supplier to confirm the details this site deliberately does not invent.

The company website organises its range into four top families: cylindrical batteries, energy storage batteries, battery chargers and fans and other hot sellers. This site follows that organisation. Within the cylindrical family there are six sub-families on the company website: 1.2V nickel batteries, 1.5V lithium ion batteries, 3.2V lithium iron phosphate batteries, 3.7V lithium ion batteries, dry batteries and cylindrical USB rechargeable batteries. Charger listings number thirty-nine titles, the 3.7V lithium family numbers twenty-four titles, the fan and hot-seller family numbers nineteen titles and the 1.2V nickel family numbers nineteen titles. Those counts are listing-title counts from the company website, not a promise that every title is a separate stocked product, and titles that repeat or carry a discontinued marking are handled exactly as published, as explained on the relevant pages.

How buyers usually narrow a rechargeable battery shortlist

Start with the size family, because size decides whether a battery fits the device at all. AA and AAA are the familiar consumer sizes; 18650, 21700 and 26650 are cylindrical sizes that appear in torches, power tools, portable power and other equipment that takes a cylindrical cell. A buyer who starts from a device manual or an existing battery should match the size family first and treat everything else as a second step.

Next, separate the chemistry family from the size family. The listings on this site name nickel families at 1.2V, lithium families at 1.5V and 3.7V, a lithium iron phosphate family at 3.2V, and dry battery families that include alkaline and carbon titles. Chemistry families differ in how they are charged and in what charger they need, so a buyer should never assume that two batteries of the same size can share a charger. The charger pages on this site therefore sit beside the battery pages rather than inside them, and the enquiry checklist asks the buyer to confirm charger fit before ordering.

Then read the listing title for what it actually says, and notice what it does not say. A listing title on this site is a title as published on the company website. It names a model, a size family or a form such as a folding head, and sometimes a figure in its wording. This site transcribes that wording and does not turn it into a specification table, a performance promise or a compatibility promise. If a title names a charging route such as USB or Type-C, that wording is reported as title wording only. The specification behind any title must be confirmed with the supplier before an order is placed, and the enquiry box at the foot of every page lists the questions to ask.

Finally, think about the use before the purchase. A battery for a remote control, a battery for a torch and a battery for a camping fan are different buying decisions even when the size family is the same, because the charger, the quantity and the way the product will be stored all differ. The guide pages on this site walk through those decisions one at a time, and the fan pages separate desk use, clip-on use, handheld use and outdoor use for the same reason.

How an enquiry moves forward

The company service page describes its service in seven steps, in this order: enquiry and communication, product design, sampling, batch production, quality inspection, export handling, and onward sale by the customer. This site reports that sequence as the company published it. It is a description of a service flow, not a delivery promise for any single listing, and the time each step takes must be confirmed for the listing in question.

The company profile also describes services beyond manufacture: custom production under the buyer's own brand arrangements, mould making with its own and partner factories, testing reports for compliance certificates, support for factory audits, and after-sales warranty support described on the company service page as worldwide. Each of those is reported here as a company-profile statement. A buyer who needs any of them should ask for it by name in the enquiry and ask what evidence the supplier can provide, rather than assuming it is included in a battery price.

A practical enquiry therefore has two halves: the product half and the confirmation half. The product half names the size family, the listing title exactly as published, the quantity range and, for chargers, the plug style. The confirmation half asks the supplier to confirm the full specification, the quantity terms and the lead time before payment. The box at the foot of every page repeats that checklist so that it is available wherever a buyer lands.

Certifications, stated plainly

The company website names CE, ROHS, SGS, UN38.3 and MSDS, and describes its factory as holding ISO 9001:2008 certification, with the year exactly as published. This site repeats those names and adds only the standard trade wording: certificates are available upon request. No certificate number, issuing body or validity date is published here, and the ISO year is not updated to a newer edition. A buyer who needs a certificate for a specific market should ask for it by name and check it against the requirements of that market.

Separately, the company's marketplace storefront is recorded as a Verified Multispecialty Supplier, verified by SGS, with nine years of operation and a Guangdong location. That is a storefront verification record, not a product certificate, and this site keeps the two statements apart rather than merging them into a single claim.

Send this, and ask these three questions

If you are ready to enquire, send the battery size family, the listing title exactly as published on this site, your quantity range and, where relevant, your charger plug style. Then ask three questions before you order: please confirm the full specification for this listing; please confirm the quantity terms that apply to my order; and please confirm the lead time. Contact: Manager Geely Zhang, telephone +8615975606040, email [email protected]. The full address is Room 401, Building 2, Area C, Longquan Information Technology Park, Dalang Street, Longhua District, Shenzhen City, Guangdong Province, China.

What to send with your enquiry

To get a useful answer first time, please include the following in your message. Every item on this list is a question for the supplier to confirm, not a claim made on this page.

• The battery size family you need (for example AA, AAA, 18650, 21700 or 26650) and the listing title exactly as published on this site.
• Your quantity range, so the supplier can confirm the quantity terms that apply to your order.
• For chargers, the plug style and the battery sizes the charger must serve.
• For fans, where the fan will be used — desk, clip-on, handheld or outdoor — and whether it must run while charging.
• Three questions to ask before you order: please confirm the full specification, please confirm the quantity terms, and please confirm the lead time for this listing.

Planning reference for quantity and lead time

Orders in this trade are commonly discussed in the low thousands of pieces for standard cells, and lead times are commonly measured in weeks once a specification has been agreed. Those are trade planning figures, not this company's published policy: the company's own website does not publish a minimum order quantity or a lead time. Before you place an order, please confirm the quantity terms and the lead time that apply to your listing, in writing, and please do not treat this paragraph as a price or delivery promise.

Prices are not published on this site. Please ask for a quotation against the exact listing title, and please confirm the specification, the quantity terms and the lead time before payment.
