The short answer: if a chainsaw comes out a handful of weekends a year for storm branches and hedge overgrowth, buy a 10–12 inch saw on whatever battery platform you already own — DeWalt, Makita, or Milwaukee — and stop there. If you’re working through a cord or more of firewood a season, the tool-platform saws run out of both power and battery capacity fast enough that a dedicated 16-inch saw on Ego’s 56V system or Stihl’s AP platform pays for itself in fewer battery swaps alone. The dividing line isn’t bar length or brand loyalty; it’s whether your woodpile is measured in armloads or in cords.

I’ve gone through more cheap chains than I can count on my own gas saw, usually because I let the tip touch dirt once too often, so when someone asks whether a battery chainsaw is worth switching to, the question that matters isn’t the saw itself. It’s what gives out underneath it, and when. Fall is when a chainsaw in most garages gets used — storm branches down, the hedge line that got away from you all summer, a stack of rounds that need splitting before the cold really sets in — and none of that tells you which specific saw to buy. What tells you something is what other owners report failing, and what the maker on the box actually promises to fix when it does.
The Part That Gives Out First, Saw by Saw
None of these six saws has cut a log at this desk. What follows is pulled from ownership reviews, retailer review pages, and the tool forums where people complain when something quits — named source by source, not averaged into a vague “some owners report.”
DeWalt’s DCCS620B shows up with the most granular data: a two-year ownership review at Tools Territory lists a chain that dulls quickly, chain tension that loosens during normal operation and needs frequent re-adjustment, an oil-fill cap that flexes and is genuinely hard to remove, and battery runtime that noticeably drops off well before the pack dies outright. None of that is catastrophic — it’s the profile of a saw that needs more fussing than the box implies, not one that breaks.
Milwaukee’s 2727-21HD draws a sharper complaint. A Tool Craze review and its comment thread carry multiple reports that the chain “falls off constantly with anything other than light use,” and one commenter traces the mechanism: the plastic hex inserts backing the chain-tension studs strip out under heat, so the studs spin freely and the chain can no longer be tensioned properly. Separate commenters on the same thread report oil leaking from the reservoir during storage, which the original review’s own claim of “very good at not leaking” doesn’t mention. Two different failure modes, both pointing at the tensioning hardware rather than the motor.
Stihl’s MSA 220 C-B is the outlier in the other direction. A two-year ownership review at Tool Box Buzz reports the tool-free tensioning system has “held up exceptionally well,” with no chain slack and no bar movement over two years of regular use — the same failure DeWalt and Milwaukee owners describe, absent here. The one recurring maintenance item is the chain-tensioner wheel clogging with sawdust and oil residue and needing periodic cleaning to keep working smoothly. A reader comment on that same review raised a general concern about motor longevity, which the reviewer hadn’t experienced firsthand — worth flagging as unconfirmed rather than dropping.
Makita’s XCU03Z produces a genuinely different kind of complaint. TechGearLab’s review doesn’t flag a wearing part at all — the recurring owner irritation is that the electronic power button has to be pressed before every single cut, and that running on two 18V batteries instead of one is an extra thing to track and charge unless you’re already deep in the Makita 18V LXT ecosystem. That’s a design complaint, not a durability one, and it’s useful precisely because it’s different: not every “problem” on this list is a part wearing out.
Ego’s CS1604 turns up a specific oiler complaint on a Hearth.com forum thread: full reservoir, clear oiling hole, no oil reaching the bar when the saw runs. It’s one documented case rather than a pattern I can quantify, but it lines up with the general shape of complaints across this whole list — the auto-oiling and tensioning systems are where these saws misbehave, far more often than the motor itself.
Greenworks’ 80V platform gets the most self-correcting thread of the six. On a Garage Journal forum thread, an owner burned through four chains with links seizing from heat, and other members talked him through the cause: cutting too close to dirt and running cheap aftermarket chains, not a flaw in the saw. “Dirt equals instant death for a chain” is how one poster put it, and the fix — keep the wood off the ground, buy Oregon or Stihl replacement chain instead of the cheapest option on Amazon — applies to every saw on this page, not just this one. Separately, Pro Tool Reviews flags runtime, not durability, as the platform’s real limitation on bigger jobs.
Line them up and a pattern falls out: on two separate brands, the chain-tensioning hardware is the first thing owners report giving them trouble, well ahead of the motor. Stihl’s saw is the exception that held that system together for two full years in an independent test. And at least one of the “failures” here — Greenworks’ seized chains — turned out to be a chain-quality and technique problem that would happen on any brand’s saw, which is a fact worth knowing before you blame the tool.
The Saw for Occasional Yard Cleanup
If the saw comes out a few times a year for storm branches and hedge overgrowth, you’re not chasing runtime — you’re chasing convenience. A 10–12 inch bar on a battery platform you already own means no second charging station and no orphan battery gathering dust in a drawer.
DeWalt DCCS620B
DeWalt’s 20V MAX XR Compact 12-inch saw is still current on dewalt.com, sold bare (no battery or charger) and listed around $189 at Home Depot, which also carries 3,749 customer reviews on that listing — a real sample size for a tool this specific. It runs on any DeWalt 20V MAX battery, so if a drill or impact driver already lives in the garage, this is close to a free add-on. Skip it if you’re starting a battery platform from scratch, or if you’re the kind of owner who won’t re-check chain tension mid-job — the Tools Territory review above says it drifts.
Makita XCU03Z
Makita’s XCU03Z pairs a 14-inch bar with a 36V setup built from two 18V LXT batteries, confirmed on Makita’s own product page, and it typically lists near $200 as a bare tool at authorized dealers. The longer bar buys more reach than the DeWalt or the Milwaukee below without stepping up to a dedicated outdoor-power platform. Skip it if carrying and charging two batteries for one tool sounds like a hassle rather than a feature — that’s the complaint that shows up most, not a broken part.
Milwaukee 2727-21HD
Milwaukee’s M18 FUEL 16-inch saw ships as a kit with a 12.0Ah High Output battery, confirmed on Milwaukee’s own site, and runs about $499 at Home Depot, where it carries 5,189 reviews. That’s the largest bar in this occasional-use group, which pushes it toward firewood-capable territory if you already own M18 batteries. Skip it if you’re buying into M18 from zero just for this saw — at full kit price it’s the most expensive tool here, and the chain-tension complaints above are worth reading before you commit.
The Saw for Regular Firewood Cutting
Cut a cord or more a season and the math changes: you need more battery capacity and more torque than a tool-platform saw is built to deliver, and the saws below run on dedicated outdoor-power batteries rather than a shared drill platform.
Ego Power+ CS1604
Ego’s 16-inch saw runs on the 56V ARC Lithium platform and is still listed at Lowe’s. The kit ships with a 5.0Ah battery, and Ego’s own product page rates it for up to 250 cuts through a 4×4 on that battery — a figure worth knowing because some older buying guides understate it. The battery also crosses over to Ego’s mowers and blowers. Skip it if the oiler complaint above worries you enough to want a saw with a longer independent track record — it’s one report, not a pattern, but it’s the only oiler-specific complaint I found on any saw in this piece.
Greenworks 80V Platform
Greenworks’ 80V chainsaw line, including the 18-inch GCS80420, is still a current listing at greenworkstools.com, though specific kit configurations have cycled in and out of stock this season — check current availability before assuming a specific bundle is sitting on the shelf. It’s the longest bar of the group here, which matters if you’re regularly bucking rounds thicker than 12 inches. Skip it if you can’t commit to buying real replacement chain (Oregon or Stihl, not the cheapest option on Amazon) and keeping the tip out of dirt — the Garage Journal thread above is a clean example of what happens when you don’t.
Stihl MSA 220 C-B
Stihl’s AP-system saw is still listed at stihlusa.com, sold through dealers rather than big-box retail, with the battery and charger priced separately from the saw itself. It’s also the only saw here with an independent two-year ownership review reporting the tensioning system held up without the chain-slack or bar-movement complaints that show up on two other brands in this piece. Skip it if you want to walk into a big-box store and walk out with everything in one box — Stihl’s dealer-only model is the tradeoff for that reliability record.
One thing worth saying plainly before naming any winner: none of the six recalls I checked applied to the saws above. Milwaukee’s chain-brake recall covers only its 12- and 14-inch top-handle models (2826-series), not the 2727-21HD. DeWalt’s 2022 recall was the corded DWCS600, not the cordless DCCS620B. Stihl’s most recent chainsaw recall was the MSA 300 C-O, not the MSA 220 C-B. All three checks came back clean as of this writing.
What Six Warranties Promise, and What They Quietly Don’t
A warranty length looks like a simple number until you read what it excludes, and every maker here excludes the exact parts most likely to fail first.
| Brand | Tool warranty (consumer use) | Battery warranty (consumer use) | What’s named as excluded |
|---|---|---|---|
| DeWalt | 3 years | 3 years | “Part failure due to normal wear or tool abuse” — not itemized by part |
| Makita | 3 years | 3 years | Defects in materials/workmanship only; exclusions not itemized in the published policy |
| Milwaukee | 5 years | 3 years (current RedLithium HD/High Output packs) | Drops, weather exposure, unauthorized repair — not itemized by part |
| Ego | 5 years | 3–4 years depending on pack (extendable to 5 with registration) | Explicitly names “chain bars, saw chains” as Routine Maintenance Parts — 90 days only |
| Greenworks | 3 years (standard line) | 3 years | “Routine maintenance items such as lubricants, blade sharpening,” and normal wear |
| Stihl | 3 years | 5 years (AP-system battery) | Normal wear, improper maintenance/storage, non-dealer parts or repair |
Two things stand out once the fine print sits side by side. First, Ego is the only one of the six that writes “saw chains” and “chain bars” into its warranty document by name, capping them at 90 days as Routine Maintenance Parts — per Ego’s own warranty policy. Every other brand here leans on a vaguer “normal wear” clause that almost certainly means the same thing in practice, but only Ego says so in writing, which makes it easier to know what you’re agreeing to before something wears out. Second, Stihl is the only brand that covers its battery longer than its tool — five years on the AP-system pack against three on the saw itself, per Stihl’s published warranty policy — which is backwards from how the other five brands split it, and worth knowing if the battery is the more expensive half of your purchase.
None of this changes the practical takeaway: a chain and a bar are consumables everywhere, full stop. Budget $15–$25 for a replacement chain and $30–$60 for a bar regardless of which of these six you buy, because no warranty on this list is going to cover either one past the return window.
How Long Should You Expect a Cordless Chainsaw Battery to Last?
Manufacturers commonly rate consumer-grade lithium-ion batteries for 300 to 500 charge cycles before capacity noticeably fades, per Battery University’s widely cited reference figures. Run the saw hard every weekend through a full season and that’s roughly two to three years before you notice the runtime dropping off — which lines up with the Tools Territory review above, where the DeWalt owner’s two-year-old battery ran noticeably shorter than it did new. Tool-platform batteries (DeWalt, Makita, Milwaukee) tend to be the cheapest to replace when that day comes, since the same pack usually powers three or four other tools already in the garage. Standalone outdoor-power batteries (Ego, Stihl) cost more per replacement, but they’re also not being drained by a drill and an impact driver on the same afternoon, which can stretch the practical cycle count out a bit further.
Bar Length, Firewood, and the Rest of What People Ask
Bar length isn’t a bigger-is-better spec — it’s a match-it-to-the-wood-you-cut spec. A 12-inch bar handles pruning and branch cleanup up to roughly 10 inches across and stays lighter and easier to control than a longer saw. A 14–16 inch bar comfortably handles firewood-sized rounds (10–14 inches) and gives enough reach to buck a log from one side instead of flipping it and cutting twice. An 18-inch bar like Greenworks’ is overkill for yard cleanup but earns its weight on anything thicker than about 12 inches. The rule of thumb that holds up: pick a bar roughly 2 inches longer than the widest log you cut regularly, since cutting a 14-inch log with a 12-inch bar means repositioning and cutting from both sides.
Can a cordless saw handle real firewood? Yes, but the 12-inch tool-platform saws above will drain a battery fast and bog down in hardwood if you lean on them for a full cord. That’s the argument for stepping up to the 16-inch Ego or Stihl, not bar length for its own sake.
Is a cordless saw safer than a gas one? Not inherently — a spinning chain and kickback risk are identical regardless of what powers the motor, and every saw here still needs a chain brake, eye and ear protection, and a chaps-and-gloves habit you don’t skip. What cordless genuinely removes is the pull-start ritual that tempts people to skip the safety check just to get the thing running, which is a real if modest edge, not a certification.
How often does the chain need sharpening? Every 2–3 hours of cutting, sooner if it touches dirt or a hidden nail in reclaimed lumber — the same interval regardless of brand or battery platform, since a chain doesn’t know what saw it’s bolted to.
Which One Wins
For most people doing fall cleanup and nothing more, the DeWalt DCCS620B is the easiest recommendation on this page — not because it’s flawless (the chain-tension drift is real, per the Tools Territory review), but because at $189 bare-tool on a battery platform most homeowners already own some piece of, there’s very little to lose by adding it to the garage. The saw I’d steer people away from here is the Milwaukee 2727-21HD at full kit price: $499 is a lot to spend on a saw with the most reported chain-tensioning complaints of the six, and it only makes sense if M18 batteries are already sitting in a drawer waiting for a job.
If firewood is the real job, Stihl’s MSA 220 C-B is the one saw here with an independent two-year track record that didn’t turn up the tensioning problems DeWalt and Milwaukee owners report — the tradeoff is buying through a dealer instead of a big-box aisle, and pricing the battery separately from the saw. By the second or third season, that reliability record is worth more than the convenience of a one-box checkout.
Other stuff that turns out to be relevant this time of year: our breakdown of cordless hedge trimmers for fall cleanup covers the tool most people reach for right alongside a chainsaw, and if warranty fine print is what decides your next tool purchase, our look at rolling tool chest coverage runs the same kind of read-the-policy exercise on a completely different category.
