Why a checklist
A checklist prevents the most common ordering mistake: ordering a battery that does not match the device, because the variant was not named, the specification was not checked, or the confirmation was skipped for speed. A battery that does not match costs time and money to return or replace, and it leaves the device without power in the meantime, so the few minutes a checklist takes are well spent.
This article collects the compatibility steps from across this site into one checklist, so a buyer can work through it before ordering, without hunting through many pages. It does not add new steps, and it does not change any model page's specification: it collects what the guides and model pages already say, in order.
Step 1: Name the exact variant
Name the exact device variant, including the model number and any further identifiers the device carries, such as a serial or configuration code. A brand or a screen size alone is not enough, because variants differ within a product line, and a battery that serves one variant may not serve another. A seller who is given only a brand cannot confirm compatibility, and a buyer who accepts a battery on that basis is taking a risk.
List every variant in the order, if ordering in bulk, with the quantity for each, so the quotation and the compatibility check cover all of them, not just one. A bulk order that assumes one battery serves all variants risks a large number of unusable batteries.
Step 2: Check the specification table
Check the model page's specification table against the variant: voltage, capacity, energy where stated, fit, connectors, and any further figures the page states. All must match together, because a battery that matches on voltage but not on fit will not serve, and a battery that fits but does not match electrically will not serve either.
Do not check a single figure, and do not assume a figure for a model that does not state one: ask in the inquiry, and check the answer against the model page. Units matter, and a figure without its unit cannot be compared, while a figure with the wrong unit cannot be trusted.
Step 3: Read the compatibility statement with attribution
Read the model page's compatibility statement, and note that it is the company profile's own statement, quoted with attribution, not a statement by the equipment maker, and it does not imply authorisation. A listing that says a battery serves a particular device means the company profile lists it for that device, and it should be confirmed, not taken as a guarantee.
If the variant is not listed on any model page, ask in the inquiry, naming the exact variant, rather than assuming a model will serve it. An unlisted variant is a question for the inquiry, where the seller can check it, not a gap to be filled by guessing.
Step 4: Check charging and temperature
Check the charging figures and the temperature ranges, where stated, against the use and the conditions: a battery that needs hours to charge must be charged well before it is needed, and a battery used outside its stated temperature ranges may not perform as expected. Do not assume a charging figure or a temperature range for a model that does not state one.
A charger should also be checked: its input, output, power, and the battery types it serves, against the batteries and the workflow. A charger with the right output but the wrong input cannot be powered, and a charger with too few slots cannot serve a team.
Step 5: Check the market and the certificates
Check the market the battery will be sold into, and ask for the certificates that apply to that market, by name, with documents attached, because certificates differ by market and by model, and a certificate for one model does not cover another. A claim that a product is certified, without naming the certificate, cannot be checked, and should not be relied on.
This site does not list certificate numbers, issuers, or validity dates, because those details are confirmed per model in the inquiry, with documents attached. A buyer who needs a specific certificate should name it in the inquiry, and should check the document against the model and the market.
Step 6: Confirm in the inquiry, before payment
Confirm in the inquiry, naming the model, the exact variants, the quantities, and the market, and ask for the specification for the exact model, the minimum order quantity, the lead time with its meaning, the warranty terms, and the certificates that apply to the market, by name, with documents attached. Do not pay before these have been confirmed for the exact models in the order.
The confirmation step is the buyer's protection against a mismatched battery, a missing certificate, or a misunderstood term, and it should never be skipped for speed. A seller who answers the checklist fully is a seller who has checked the order, and a buyer who asks it has done the work that prevents a costly mistake.
The checklist in short
Name the exact variant, check the specification table, read the compatibility statement with attribution, check charging and temperature, check the market and the certificates, and confirm in the inquiry, before payment. Six steps, in order, each taking a few minutes, together preventing the most common ordering mistake.
Keep this checklist with the order, and refer to it for every order, not just the first, because variants, markets, and models change, and a checklist that is used once and forgotten will not prevent the next mistake. The inquiry page explains how to write the inquiry, step by step.
A note on sources and confirmation
The model specifications and compatibility statements referred to in this article come from the company profile's official product pages, as presented on this site's model and category pages. Compatibility statements are the company profile's own statements, quoted with attribution, and they are not statements by the equipment makers, nor do they imply authorisation, endorsement, or original manufacture. A specification stated for one model is not carried to another model, and a figure stated for one model should not be assumed for any other.
Figures that are not stated on a model page — a price, a minimum order quantity, a lead time, a warranty period, or a certificate for a specific model and market — are confirmed per order in the inquiry, and this article does not invent them. A buyer who needs any of those should ask for it by name, for the exact model and the exact equipment variant it must serve, with documents attached where documents are what is needed, so the answer is specific rather than general.
Before ordering, name the model, the exact equipment variant it must serve, the quantity you have in mind, and the market you sell into, in the inquiry. Ask for the specification for the exact model, the minimum order quantity, the lead time with its meaning, the warranty terms, and the certificates that apply to your market, by name, with documents attached. Do not pay before these have been confirmed for the exact models in the order, because payment removes the leverage to resolve an unconfirmed item, and a confirmed order is the only basis for a safe purchase.
