The biggest lie in the gas chainsaw aisle is that you need a carburetor, a pull cord, and a cloud of blue smoke to get real work done. Battery technology has quietly passed the tipping point: a top-tier cordless saw now rips through a 10-inch oak log faster than a 40cc gas unit and does it without earplugs or a chiropractor visit. If you are still mixing fuel for light duty work, you are paying a tax in maintenance time and shoulder strain that no longer makes sense.
I’m Mohammad Maruf — the founder and writer behind Gardening Beyond. I’ve spent the last 15 years analyzing market data, comparing battery platform ecosystems, and studying aggregated owner feedback on over 4,000 power tool models to separate the genuinely capable saws from the overpriced toys.
This guide cuts through the voltage hype and delivers a precise, data-backed breakdown of the best battery chainsaw options available today so you can spend your money on cut quality, not marketing fiction.
How To Choose The Best Battery Chainsaw
A battery chainsaw is a platform purchase, not a single tool decision. The batteries you buy for the saw will likely power your trimmer, blower, and hedge cutter next season. There are three key specs that separate a well-engineered machine from a frustrating one.
Bar Length and Chain Speed
Bar length determines the maximum diameter of wood you can cut in one pass — a 14-inch bar handles an 8-inch log cleanly, while an 18-inch bar reaches through a 12-inch trunk. Chain speed, measured in feet per second, dictates how fast the cut proceeds. A high chain speed (above 70 ft/s) feels aggressive and smooth; a slow one binds easily and requires more downward pressure. For most homeowners, 14 to 16 inches with a 70+ ft/s chain speed is the sweet spot.
Battery Voltage and Amp-Hour Rating
Voltage determines the saw’s torque ceiling: 40V systems handle limbing and medium bucking, while 60V and 80V platforms compete directly with gas saws on large-diameter cuts. Amp-hours (Ah) determine runtime, but capacity comes with weight. A 5.0Ah battery adds roughly two pounds over a 2.5Ah pack. The best strategy is to start with a 4.0Ah or 5.0Ah pack and buy a second smaller battery for light trimming where weight matters more.
Chain Pitch, Gauge, and Tensioning System
The chain’s pitch (distance between drive links) and gauge (width of the drive link tang) determine how smoothly the saw cuts and how easily you can find replacement chains. Low-profile .043-inch gauge chains reduce kickback but dull faster on dirty wood. Tool-free tensioning is a must-have — you will adjust the chain several times per session as the metal heats and expands, and fumbling for a wrench in the middle of a cut is a productivity killer.

In-Depth Reviews
1. Husqvarna Power Axe 350i Cordless Electric Chainsaw
Husqvarna’s Power Axe 350i is an 18-inch, 40V brushless machine that delivers cutting power comparable to a 50cc gas saw. The X-Cut chain holds its edge noticeably longer than standard chains, and the Boost Mode button gives you a 25% torque increase on demand for buried cuts in dense hardwoods. At just 7.72 pounds, it feels dead-balanced in the hand, making overhead limbing far less fatiguing than any gas alternative.
Owner feedback consistently highlights the instant start and quiet operation — no pull cord, no earplugs needed for light work. The tool-free chain tensioning system uses a dial on the side, though a few users noted the plastic tensioner mechanism can deform if the chain pinches during a cut, requiring disassembly to reset. The included 7.5Ah battery delivers roughly 30 to 45 minutes of continuous heavy cutting, which is enough for a full morning of cleanup on a standard suburban lot.
Battery compatibility across the entire Husqvarna 40V handheld line is a genuine ecosystem advantage, but the 7.5Ah pack and charger are included in the kit, so you avoid the shock of the replacement cost upfront. For the homeowner who wants gas-level power without the fumes, altitude issues, or pull-start frustration, this is the most complete package on the market right now.
What works
- Boost Mode provides 25% more torque when needed
- X-Cut chain holds sharpness longer
- Extremely light at 7.72 lbs
What doesn’t
- Plastic chain tensioner can deform under pinch load
- Included charger is 1A (6-7 hr full charge)
- Replacement batteries are expensive
2. Makita XCU04PT1 36V (18V X2) LXT Brushless 16″ Chain Saw Kit
Makita’s XCU04PT1 uses two 18V LXT batteries in series to produce 36V of direct-drive torque, and the outer-rotor brushless motor delivers the equivalent of a 32cc gas saw. The kit includes four 5.0Ah batteries, effectively giving you two full pairs to rotate through a long workday without any charger wait. The variable-speed trigger and 0-3,940 FPM chain speed give excellent control for precise limbing cuts near a fence line or house siding.
User reports consistently praise the tool-less chain adjustment and the fully sealed oil system that doesn’t leak during transport. The 16-inch bar lets you buck through logs up to 12 inches in diameter with no second pass. Some owners noted that the included Oregon chain jumped the bar after 4 to 6 hours of use and damaged the drive sprocket, but a replacement Oregon R56 chain solved the issue permanently. At 22 pounds with batteries, it is the heaviest saw on this list, yet the balanced weight distribution makes it feel more manageable than the raw number suggests.
For anyone already invested in the Makita 18V LXT platform, this saw is the most intelligent upgrade you can make — you already own the batteries, and the 4-pack in the box extends your entire tool lineup’s runtime. The 3-year warranty on the tool, batteries, and charger adds a layer of long-term confidence that budget brands cannot match.
What works
- Four 5.0Ah batteries in the box
- No-leak oil system
- Equivalent power to 32cc gas saw
What doesn’t
- Heavy at 22 lbs with batteries

3. EGO Power+ CS1611 16″ Battery Chainsaw
The EGO Power+ CS1611 runs on a 56V ARC Lithium platform that delivers genuine 40cc gas-level performance. The 16-inch bar and low-kickback chain combine with a 20 m/s chain speed to make cuts that feel as aggressive as a Stihl MS 250. EGO claims up to 130 cuts on a 4×4 with the included 2.5Ah battery, and real-world users confirm that number holds true for green softwood — dropping to about 80 cuts on seasoned hardwood. The IPX4 weather-resistant construction means you can keep working through light rain without worrying about water ingress in the electronics.
Owner feedback consistently highlights the near-zero vibration at the handle. Multiple reviews mention that the saw causes none of the hand numbness or joint soreness that gas saws induce after 30 minutes of use. The tool-free chain tensioning system is straightforward, though a few users reported the chain derailing easily if a small twig gets caught between the bar and the chain. The included 2.5Ah battery is lighter than the larger packs, which keeps the total weight around 9 pounds and makes one-handed limb retrieval feasible.
The EGO ARC Lithium battery platform now spans over 70 tools, so this saw is a strategic entry point into an ecosystem that includes mowers, trimmers, blowers, and even snow throwers. The 5-year tool warranty and 3-year battery warranty are competitive, and the cut speed per dollar ratio is the highest in the 16-inch class.
What works
- Near-zero vibration for fatigue-free cutting
- IPX4 weather resistant
- Gas-equivalent cut speed
What doesn’t
- Chain derails on small debris
- Bar oil not included
- 2.5Ah battery is small for heavy use
4. Caterpillar DG631 60V Brushless 18″ Chainsaw
The Caterpillar DG631 brings 60V of grunt to the 18-inch class with a brushless 2.0 motor that generates 40% more power than standard brushless designs and an impressive 78.7 ft/s chain speed. That chain speed is faster than any other 18-inch battery saw in this lineup, translating to a smooth, almost effortless cut through 12-inch seasoned oak. The slimmer .043-gauge low-kickback chain reduces friction and improves efficiency, though it also means the chain wears faster when hitting dirt or sand-embedded bark.
Users frequently mention the saw’s light feel relative to its output. At 13.1 pounds with the 5Ah battery installed, it is nearly 3 pounds lighter than comparable 60V saws. The inertia chain brake and reduced-kickback bar nose provide a solid safety layer for less experienced operators. However, some owners reported that the supplied bar and chain suffer from soft metal burrs and kickback issues under heavy load, with several recommending an immediate upgrade to an Oregon 16-inch bar and chain for better durability. Battery longevity feedback is mixed — some users get a full hour of heavy cutting, while others experienced battery performance degradation after 10 to 15 charge cycles.
For the price, the DG631 is a genuine value play in the premium tier. It includes a 5Ah battery and 3A charger in the box, and the tool-free tensioning dial works reliably once you understand the click-index mechanism. If you need maximum bar length and chain speed without paying professional tool prices, the Cat delivers serious capability.
What works
- Highest chain speed in class at 78.7 ft/s
- Light for an 18-inch saw at 13.1 lbs
- Includes 5Ah battery and 3A charger
What doesn’t
- Stock bar and chain have durability issues
- Battery performance can degrade prematurely
- Oil cap threads prone to stripping
5. Milwaukee Electric Tools 2727-21HD 16″ Chainsaw Kit
The Milwaukee 2727-21HD is an undisputed beast in the cordless saw category, rated at a staggering 5.3 HP equivalent from its brushless motor and a 16-inch bar. This saw is built for the pro user who needs to limb and buck on a job site all day. The overload protection circuit prevents motor damage when the chain binds, and the saw powers right back up once the obstruction clears.
Owner feedback from arborists and general contractors is overwhelmingly positive, though the saw does have some quirks. The trigger safety design includes an awkward hole that some users find uncomfortable during extended cuts, and the battery placement makes the saw feel nose-heavy when held one-handed. The large 12.0 Ah battery is essential for serious work — the smaller 5.0 Ah pack overheats and shuts down under load. Some users report that the saw leaks bar oil when stored on its side, which is a minor annoyance for truck-bed storage.
For professionals already on the Milwaukee M18 platform, the 2727-21HD is the only logical choice. The kit includes the saw, a 12.0 Ah HD battery, and a rapid charger, but you will want a second 12.0 Ah battery for all-day production cutting. The 5-year warranty on materials and workmanship adds a layer of trust that commercial users demand.
What works
- 5.3 HP equivalent power is class-leading
- Overload protection prevents motor damage
- Matches gas saw performance on big wood
What doesn’t
- Leaks bar oil during storage
- 5.0 Ah battery overheats under heavy load
- Battery placement makes saw nose-heavy
6. SKIL PWR CORE 40 Brushless 14″ Chainsaw – CS4555-10
The SKIL PWR CORE 40 cuts faster than any other 40V competitor in this price tier, thanks to a digital brushless motor that delivers efficient high torque without the weight of a metal gearbox. The 14-inch bar is perfect for storm cleanup on suburban lots, handling branches up to 8 inches in diameter without bogging down. The included 2.5Ah battery charges from 0% to 30% in just 15 minutes using the Auto PWR Jump charger, which means a quick coffee break is enough to get back to cutting.
Owners consistently praise the tool-free chain tensioning dial and the auto-lubrication system that keeps friction low without manual intervention. The anti-kickback brake adds a needed safety layer, especially for users transitioning from gas saws who are used to the inertia shutoff. Battery runtime averages about an hour of mixed cutting, and a second battery solves the all-day session problem completely. Some users felt the plastic housing components felt less robust than metal-bodied saws, though no reported failures indicate any structural weakness under normal homeowner use.
The weather-resistant construction adds durability for damp conditions, and the SKIL PWR CORE 40 battery platform now includes over 20 tools, making this a smart entry point into an affordable ecosystem. For a homeowner who wants a reliable, low-maintenance saw that starts every time and handles 90% of yard cutting needs, the SKIL delivers a compelling value proposition.
What works
- Fastest cut speed in 40V class
- Auto PWR Jump charger (15 min to 30%)
- Tool-free chain tensioning works smoothly
What doesn’t
- Plastic housing feels less robust
- Battery lasts ~1 hour under load
- Lacks felling marks on the bar
7. Worx 40V 14″ Cordless Chainsaw Power Share – WG384
The Worx WG384 uses two 20V Power Share batteries in series to produce 40V of cutting power in a compact, lightweight package. At roughly 10.4 pounds with both batteries installed, it is one of the lightest 14-inch saws on the market, making it an excellent choice for users who lack upper body strength or need to make cuts in awkward positions. The automated chain tensioning system is a genuine time-saver — the saw self-adjusts tension during operation, eliminating the periodic manual tweaks required on most competitors.
Owner feedback highlights the saw’s ability to punch above its weight class. Multiple users have cut through 9-inch dense beech and 10-inch hardwood logs without the saw stalling, a testament to the brushless motor’s torque curve. The Quick Stop chain brake is aggressive and requires a deliberate pull to disengage, which is a safety plus but can frustrate new users who expect lighter resistance. The included battery level indicator on the saw body gives you a clear read of remaining charge before you start a cut, preventing mid-job dead battery surprises.
The Worx Power Share platform’s compatibility across 20V and 40V tools is a major ecosystem advantage, and the dual-battery design means you can share packs with all your other Worx tools without voltage mis-matches. Some users noted the chain feels thin and requires more frequent sharpening than standard 3/8-inch chains, and the chain popped off the bar more frequently on knotty wood. For a lightweight, agile saw that excels at limbing and small-diameter clean-up, the WG384 is a solid mid-range performer.
What works
- Very light at 10.4 lbs
- Automated chain tensioning
- Battery level indicator on saw
What doesn’t
- Chain feels thin and dulls quickly
- Chain pops off on knotty wood
- Chain brake requires hard pull
8. Greenworks 40V 12″ Cordless Compact Chainsaw – CS40B210
The Greenworks CS40B210 is the entry-level saw that refuses to act like one. The 40V 2.0Ah battery delivers up to 50 cuts on a 4×4 treated post, and the 12-inch low-recoil bar makes it ideal for pruning, storm cleanup, and camping trips where weight matters. At just 6 pounds, it is the lightest saw on this list by a wide margin, and the wrapped grip reduces hand fatigue during extended overhead cuts. The battery doubles as a USB power bank for charging phones or tablets, a thoughtful feature for off-grid use.
Owner feedback is overwhelmingly positive for light-duty use. Users consistently mention that the saw cuts straight, the chain stays on the rails during normal operation, and the dual safety start (lock button plus trigger) prevents accidental startups effectively. Battery runtime is about 40 to 60 minutes of mixed cutting, which is adequate for weekend pruning sessions. The tool-free auto-tensioning system works well, though a few users reported that the chain loosens quicker than expected and requires more frequent adjustment than larger saws.
The Greenworks 40V platform is one of the most widely available and affordable cordless ecosystems, with over 75 tools sharing the same battery. The 3-year warranty on both the tool and battery provides peace of mind for the price point. For a homeowner who needs a dedicated limbing saw or a lightweight backup for the truck, the CS40B210 is the smartest budget-friendly buy on the market.
What works
- Ultra-light at 6 lbs
- Battery doubles as USB power bank
- Excellent for tight spaces and ladder use
What doesn’t
- Chain loosens quickly under load
- 12-inch bar limits max cut diameter
- Not suitable for hard or dry wood
9. DEWALT 20V MAX 12″ Cordless Chainsaw – DCCS621P1
The DEWALT DCCS621P1 is a 12-inch compact saw built for the millions of users already on the 20V MAX platform. The high-efficiency brushless motor delivers up to 100 cuts per charge on a 4×4, a remarkable figure for a 20V saw that speaks to the drivetrain’s efficiency. The low-kickback bar and chain reduce the risk of dangerous reactive forces, and the lightweight design (under 13 pounds with battery) makes it easy to maneuver for precision cuts in construction and demolition applications.
User feedback is mixed but generally positive for its intended use case. Homeowners praise the long battery life and the ability to cut through 8-inch oak trees with a single 5.0Ah battery lasting through dozens of cuts. Professional users note that it is not a substitute for a 14- or 16-inch gas saw on heavy-duty tasks, but it excels at quick cuts on 2- to 4-inch limbs and construction lumber. The included DCB205 5.0Ah battery and charger get you started immediately, and the oil reservoir is generously sized, requiring fewer refills per session.
Some owners reported that the chain dulls quickly if it contacts dirt or sand, and the bar requires a sharpening-grade chain more frequently than premium aftermarket chains. The saw integrates perfectly with the entire DEWALT 20V MAX ecosystem, meaning your existing drill batteries work in a pinch. For a contractor who needs a lightweight saw for rough carpentry and occasional tree work, the DCCS621P1 is the most logical extension of the DEWALT platform.
What works
- Up to 100 cuts per charge on 4×4
- Works with 20V MAX platform batteries
- Large oil reservoir
What doesn’t
- Chain dulls quickly on dirt contact
- Not as powerful as 14-inch gas saws

Hardware & Specs Guide
Bar Length and Chain Gauge
Bar length determines the maximum diameter of wood you can cut in one pass. A 14-inch bar handles up to 8-inch logs; an 18-inch bar reaches 12-inch trunks. Chain gauge (.043 inch vs .050 inch) determines how wide the bar groove must be — the slimmer .043 gauge reduces kickback but wears faster. Most consumer saws use .043 gauge, while professional saws prefer .050 for durability. Always match replacement chain pitch and gauge exactly to the bar marking.
Brushless Motor and Voltage
Brushless motors are standard on every mid-range and premium battery chainsaw because they deliver 25-40% more torque than brushed motors while running cooler and lasting longer. Voltage is the primary torque determination: 40V systems are adequate for limbing and occasional bucking, 56V and 60V systems compete directly with 40cc gas saws, and 80V or 36V (18Vx2) systems match 50cc gas output for large-scale felling. Do not underestimate the value of a high-voltage system if you regularly cut wood over 10 inches in diameter.
