Start with the device, not the battery
Every rechargeable battery purchase should start from the device it will power. Check the size the device takes, the voltage family it expects and the charger it already uses, before looking at any listing. A battery that is the right size but the wrong family, or the right family but charged the wrong way, is a failed purchase even if the price looked attractive. The device manual, the marking inside the battery compartment and the battery being replaced are the three sources that settle those questions, and they should be consulted before a shortlist is drawn up.
Where the device marking is worn or missing, the safest route is to enquire with the supplier using the old battery's size family and any wording printed on it, and to ask the supplier to confirm the match. Do not guess from a photograph or from a similar-looking listing. A short message with the size family and the device type will get a more reliable answer than a long message that guesses at a specification.
Size families, in plain language
Consumer sizes AA and AAA cover remote controls, clocks, small torches and toys. Cylindrical sizes 18650, 21700 and 26650 cover torches, portable power and equipment built around a cylindrical cell. Small cylindrical sizes such as 14500 and 16340 cover compact devices where a full-size cylindrical cell will not fit. Each size family is a physical commitment: a battery must fit the compartment, and a charger must accept the size. No figure in a listing title changes a physical fit.
Buyers who stock several sizes should keep the size families separate in their own records, even when ordering from one supplier. Mixing size families in a single order line is a common source of warehouse errors, and it makes later reordering harder. Order by size family, label by size family, and store by size family.
Chemistry families, and why they must not be mixed
The families on this site are 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 decides the voltage family and the charging route, so two batteries of the same size in different families are different products. A charger must be confirmed to suit the family being ordered; physical fit alone is not enough.
USB-charged titles add a further distinction: the charging route is built into the battery rather than supplied only by an external charger. That is convenient, but it means the buyer must confirm the charging route for the exact title, since titles differ in their wording and the published record does not expand those differences into specifications.
What a listing title proves, and what it does not
A listing title on this site is transcribed exactly as published on the company website. It proves that a listing with that wording exists. It does not prove a capacity, a voltage, a cycle count, a charging speed or a compatibility claim, even when the wording contains a figure. Figures inside titles are reported as title wording, not as confirmed specifications, and this site never turns a title into a specification table.
That restraint is deliberate. A buyer who treats title wording as a specification will eventually order on a misunderstanding, and the misunderstanding will surface only after delivery. The enquiry checklist at the foot of every page exists to close that gap before payment: please confirm the full specification, the quantity terms and the lead time for the exact title.
Quantity, lead time and price: ask, do not assume
Prices are not published on this site, and the company's own website does not publish a minimum order quantity or a lead time. For planning, 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, and they must be replaced by confirmed figures for your order.
A quotation should therefore be requested against an exact listing title, with the quantity range stated, and it should be read together with the confirmed specification and lead time. If any of those three is missing from the supplier's reply, ask for it before committing. A complete quotation is one that answers all three questions, not one that answers only the price.
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.
