Reselling power tools from auctions: test the tool, the battery, and the kit before you list

Reselling · 9 min read

General information only, not financial, legal, or safety advice. Resale results vary and no income or profit is promised or guaranteed. Tool testing involves powered equipment and lithium-ion batteries — follow the manufacturer instructions for the specific model, and do not test or sell a tool or battery that shows damage.

Power tools look like the easiest auction flip on the shelf. The brands are familiar, the buyers are easy to picture, and a cordless drill seems to explain itself. The margin, though, is rarely decided by the tool body alone. It is decided by three things the catalog photo cannot show: whether the exact model is clear of recalls, whether the tool runs cleanly under a real check, and whether the battery and charger in the box turn the listing into a usable kit or leave the buyer shopping for the expensive half of the product. A reseller who lists first and learns those answers from buyer messages has the order backwards. The bench comes first, and the listing is simply the bench record written for a buyer.

A power tool is three products in one box

Think of every cordless tool lot as three separate products sharing a case. The first is the tool itself: motor, chuck or blade mount, gearbox, switches, guards, and housing. The second is the energy system: battery packs and the charger that serves them. The third is the platform — the battery family the tool belongs to. That third product is not a detail. DEWALT, for example, documents its 20V MAX batteries as compatible with all 20V MAX tools and chargers, and sells starter kits that bundle a battery with a charger separately from tool-only products where the battery and charger are sold separately. A buyer who already owns packs on that platform can use a bare tool the day it arrives. A buyer who does not owns an ornament until more money is spent. The same physical drill is therefore a complete purchase for one buyer and half a purchase for another, and the listing has to say clearly which one is on offer.

That split is also why auction lots of tools disappoint in both directions. A lot described as a drill kit may contain a sound tool, a charger, and a battery with badly degraded capacity — degraded capacity is common in used cordless tools, according to used-tool evaluation guidance. Another lot described loosely as a bare tool may include a working charger and a healthy pack that were simply never photographed together. Neither fact is visible at bidding time, which is exactly why the pre-listing routine below starts with identification, not photography.

Step zero: identity and recall status before any test

Before a battery goes on a charger, record the brand, the exact model number from the tool's label, the battery model, and the charger model. If the label is missing or illegible, that is information too: an unidentifiable tool cannot be recall-checked properly, cannot be matched to its platform with confidence, and should be priced and described accordingly — or not listed at all. A legible model number is what lets a seller (and later, a buyer) verify the tool against manufacturer information instead of guessing from the shape of the housing.

The recall check comes next, and in Canada it is not a courtesy step. Health Canada recall notices state that the Canada Consumer Product Safety Act prohibits recalled products from being redistributed, sold, or even given away in Canada. That prohibition covers the friendly options a reseller might reach for — there is no compliant version of listing a recalled chainsaw cheaply, adding it to a bundle, or giving it away with another purchase. The US Consumer Product Safety Commission's resellers guide makes the same point from the other side of the border: before reselling any electrical product, check for recalls. For a Canadian seller the practical routine is short: search the exact model (and the battery and charger models, which can be recalled separately) against Health Canada's recall database, follow the recall's stated remedy if there is one, and keep a note of the check with the item's record. A tool that fails this gate does not get tested for sale. It leaves the inventory through the recall remedy or proper disposal, and its cost is recorded as a loss on the lot — which is useful sourcing information, not just a bad day.

The bench routine, in order

Run the same routine on every tool, in the same order, and write the result down before the listing is drafted. Consistency is the point: a routine that changes with mood produces listings that claim different things for the same condition. On the sourcing runs behind this site, the standing rule is that items are checked before a buyer ever sees them, because an unhappy buyer costs more than the minutes a check takes.

1. Inspect cold, before power. Work through the housing, cord or battery contacts, guards, and controls. Look for cracked housings, corrosion, damaged guards, and signs of overheating such as discoloured plastics. On corded tools, examine the full length of the cord and the plug: the CPSC resellers guide says equipment with frayed or damaged cords or plugs should be discarded, not repaired with tape and optimism. Check that guards move and return as they should, and that switches and interlocks are present and operate mechanically.
2. Check the moving parts by hand. Rotate chucks, arbors, and shafts manually and feel for play, binding, roughness, or grinding in bearings and gears. A drill chuck that wobbles or a saw arbor with side play is telling the same story a powered test would, without the risk of running a damaged tool.
3. Power up safely. The CPSC guide advises caution when powering devices to assess them for resale, including plugging into a GFCI-protected receptacle — and if the GFCI trips, disposing of the product rather than listing it. Run the tool briefly at each speed setting, operate the variable-speed trigger and any reverse or clutch settings, and listen. The run should sound smooth and consistent; grinding, rattling, irregular speeds, excessive vibration, smoke, or a burning smell each end the test and the listing plan for that tool in its current state.
4. Test under light load where it is safe to do so. A drill that spins freely but stalls driving an ordinary screw into scrap wood, or a saw that bogs immediately in soft material, has not passed in any sense a buyer would accept. Used-tool refurbishment guidance sequences the work the same way: verify identity and platform, clean housings and contacts, test the batteries, address worn parts, and finish with a load test. Keep the load modest and appropriate to the tool — the goal is evidence, not a stress contest.
5. Test the battery and charger as their own items. Charge each pack on its matching charger, watch for abnormal heat during charging, check any fuel gauge (DEWALT's 20V MAX packs, for instance, carry a 3-LED fuel gauge showing state of charge), then run the pack in the tool and note how it behaves. Record the result per pack, not per lot: one strong pack and one weak pack is a common lot outcome and the listing must not average them.
6. Decide, grade, and record. Write the outcome into the item record in plain language — what was checked, what passed, what did not, and what is included. That record becomes the listing text, the answer file for buyer questions, and the evidence if a buyer dispute ever needs one.

Success looks like this: every tool on the shelf has a one-line bench record a stranger could re-run and get the same result — identity confirmed, recall check dated, function and load result noted, each battery's result noted separately, and a listing decision that follows from the record rather than from hope.

The battery is a system, not an accessory

Lithium-ion tool batteries deserve their own paragraph because they carry both the value and the risk in a cordless lot. Health Canada's battery-safety guidance for larger lithium-ion products — a category that explicitly includes power tools and circular saws — warns that fires in these products can be severe and hard to extinguish, and gives rules that map directly onto resale decisions. Use the original battery and charger that came with the device, and contact the manufacturer or retailer for a replacement rather than substituting an unknown pack. Never modify or tamper with a battery, and never use a damaged or modified one: packs that are worn out or show signs of damage should be disposed of, following municipal guidance for safe battery disposal. Chargers should carry a Canadian certification mark such as CSA, cUL, or cETL.

Translated into bench rules: a swollen, cracked, leaking, or heat-damaged pack is not a discount item, it is a disposal item, and it never ships. A pack that will not take a charge, or gets unusually hot while charging, gets the same treatment. A pack that charges normally, shows a sensible fuel-gauge reading, and runs the tool under light load is a tested pack, and the listing can say exactly that — charged, run in the tool, and observed — without claiming a capacity percentage that was never measured. Note also the voltage language on the label when describing a platform: DEWALT states that its 20V MAX figure is the maximum initial battery voltage measured without a workload, with a nominal voltage of 18. Copying the platform name accurately, rather than inflating it, is spec verification in its simplest form — the listing repeats what the manufacturer documents, nothing more.

Bare tool, complete kit, parts, or no listing: the decision table

Two of these rows deserve emphasis. The bare-tool row is not a failure: because platform batteries are shared across a whole tool family, a tested bare tool is a complete purchase for the large group of buyers already on that platform, and used-tool guidance confirms that platform compatibility, the presence of an original charger, the number of usable batteries, and documented history are precisely the things that drive resale value. The kit row earns its premium from verification, not from throwing items in a box — a kit whose battery was charged and run in the tool is a different product from a kit assembled by proximity. And the parts row has a hard boundary: parts language is honest only when the listing leads with the failure. A tool that does not run, listed with the word "untested" by a seller who did test it, is the kind of mismatch that follows a seller's account for a long time.

Listing language that matches the bench record

The listing is the bench record translated, and the translation rule is strict: the listing may claim only what the routine actually checked. "Tested" should name the test — powered on, run at all speeds, drove screws into scrap pine, battery charged and run in the tool — rather than float as a general promise. Cosmetic condition gets the same treatment. On the runs behind this site, the companion rule is that items must match what the listing says: if a housing is scuffed, the scuff is mentioned or clearly visible in the photos, not cropped out of the frame. Photograph the model label, the battery contacts, the charger, and every included accessory laid out together; for shipped listings, evaluation guidance for remote buyers suggests a short video of the tool running under load answers the question a distant buyer most wants answered. Finally, weigh the finished kit before choosing a channel. Heavy corded tools and multi-battery kits often belong in local pickup, where the buyer can also see the tool run; lighter cordless tools travel better. That is a routing decision to make from the scale and the bench record, not after a shipping quote surprises both sides.

FAQ

Can a recalled power tool be sold cheaply, or given away with another item? No. Health Canada's recall notices state that the Canada Consumer Product Safety Act prohibits recalled products from being redistributed, sold, or even given away in Canada. Follow the recall remedy or dispose of the item properly, and record the loss against the lot.

Is "untested" an acceptable description for an auction tool? Only when it is literally true, and it caps the price at parts-level expectations. If the tool was powered and checked, the listing should say what was checked. If it genuinely cannot be tested — no compatible battery exists on hand, for example — say that specifically, and price it as untested rather than implying it probably works.

Should a weak battery be included in a kit to make it look complete? No. A pack that will not hold a useful charge makes a kit worse, not better, because the buyer discovers it immediately. Sell the tool bare, keep a genuinely tested spare pack for a future lot on the same platform, and dispose of damaged or swollen packs through municipal battery disposal — never ship them.

Does a bare tool sell? Yes, to buyers already on the platform — battery families are shared across many tools from the same maker, which is why manufacturers sell tool-only versions at retail. The listing's job is to name the platform and required battery clearly so the right buyers find it and everyone else scrolls past.

General information only, not financial, legal, or safety advice. Verify a specific tool's recall status and manufacturer instructions before testing or listing it; fee schedules, platform lineups, and recall notices change.
