A few years ago, buying a chainsaw was a simple conversation: how big is the tree, and how much gas tank do you want? That is no longer true. Battery chainsaws have closed the gap on cutting power to the point where they handle the majority of homeowner cutting work without complaint. The old battery versus gas argument is now much more about your cutting style, your patience with maintenance, and how often you actually run a saw.
Here is how the two compare in the real world, where the gap still matters, and what each one actually costs you over five years of ownership.
The Quick Answer
Homeowner cutting under 10 inches: a battery chainsaw is almost always the smarter tool. It is instant to start, quiet, and has enough power for firewood, storm cleanup, and limbing.
Logs over 14 inches, or full days of cutting: a gas chainsaw still wins on raw endurance. Unlimited runtime and top-end cutting torque is hard to match on batteries.
Undecided, mixed use, or a cabin owner: a mid-range battery chainsaw with a spare battery handles more than most people expect. Rent or borrow a gas saw for the occasional large-log job.
How Chainsaw Power Actually Works
When people talk about chainsaw power, they usually mean one of two things: motor rating or actual cutting speed in wood. These are not the same number, and specs can mislead.
Motor power: CC vs Volts and Amp Hours
Gas chainsaws are rated by engine displacement in cubic centimeters. A 40cc saw is a typical homeowner size. A 60cc saw is professional. Battery chainsaws are rated by voltage (40V, 60V, 80V) and battery capacity in amp hours. Higher voltage and higher amp hours together roughly translate to more sustained cutting power and longer runtime.
Cutting speed in wood
The number that matters most in the shop is how fast the saw actually moves through a standard log. A modern high-voltage battery chainsaw cuts 8-inch seasoned hardwood at roughly the same pace as a 40cc gas saw. The Wild Badger 40V 16-inch cordless chainsaw, for example, runs a 7500 RPM brushless motor with chain speeds near 50 feet per second, which is enough to cut firewood-grade hardwood without lag. On very large logs (16 inches or more), a gas saw still pulls away because its engine does not sag under load the way a battery motor can when it nears its draw limit.
Bar length sets the job size
A chainsaw can cut wood up to roughly twice its bar length by working from both sides. A 16-inch bar comfortably handles logs up to about 30 inches. Battery chainsaws now ship with 12 to 18-inch bars. The Wild Badger lineup covers the common homeowner range with a 20V 12-inch compact saw for limbing and light work, and a 40V 16-inch cordless saw for firewood and storm cleanup. Gas saws commonly reach 18 to 24 inches, which is where the gap shows up for anyone dealing with big trees.
Battery Chainsaw: Strengths and Limits
A battery chainsaw is powered by a rechargeable lithium battery and an electric motor. It is instant on, has very little vibration, and needs almost no maintenance beyond chain tension and bar oil.
Where a battery chainsaw shines
- Start-stop work: limbing, pruning, and cleanup where you make one cut, walk, and cut again. No idle, no flooded carb, no wasted fuel.
- Urban and suburban use: quiet enough to run early morning without a complaint from the neighbors.
- Homeowner firewood: a single battery typically cuts 40 to 100 logs in the 6 to 10-inch range before needing a swap. A 4.0 Ah pack like the one that ships with the Wild Badger 40V cordless chainsaw covers a typical weekend firewood run comfortably.
- Storm cleanup: instant start on the day you need it, after the saw has been sitting for six months. Automatic lubrication and tool-free chain tensioning (both built into the Wild Badger 40V saw) remove the two most common reasons homeowners hesitate to reach for a chainsaw.
Where a battery chainsaw struggles
- Very long sessions: running a saw continuously for four hours means three or four batteries on rotation. Gas is still simpler.
- Very large logs: a 16 to 18-inch log pushes most homeowner battery saws near the limit of what they can hold torque on.
- Cold weather: battery capacity drops in freezing temperatures. Plan for roughly 20 to 30 percent less runtime.
Gas Chainsaw: Strengths and Limits
A gas chainsaw runs on a two-stroke engine burning pre-mixed fuel. It is louder, heavier, and more work to maintain, but it is also the tool that earned the chainsaw its reputation.
Where a gas chainsaw shines
- All-day cutting: refuel in under a minute, keep working. No charge cycles, no planning around battery count.
- Heavy timber: sustained torque on 16 to 24-inch logs without sag. Bucking up fallen oak or clearing a large blow-down is still gas territory.
- Remote use: a cabin, a back acre, or a farm with no convenient charging is still easier with a gas tank and a jerry can.
- Professional work: tree surgeons and loggers still largely run gas for raw cutting speed at the top end.
Where a gas chainsaw struggles
- Startup: a cold saw that has been sitting for a season is a coin flip. Carburetor gumming, old fuel, and fouled plugs are all common.
- Noise and vibration: 100+ dB at the operator, plus hand-arm vibration that can fatigue you in under an hour.
- Maintenance: fuel mix, carburetor, spark plug, air filter. A gas saw rewards regular attention and punishes neglect.
- Emissions and regulations: some states and cities now restrict or tax small two-stroke engines.
Total Cost Over 5 Years
The sticker price is only half the story. Once you add fuel, maintenance, and replacement parts, the five-year comparison often surprises homeowners.
| 5-Year Cost Category | Battery Chainsaw | Gas Chainsaw |
|---|---|---|
| Saw purchase | $180 to $320 | $180 to $400 |
| Battery (or fuel, 5 yr) | $120 spare + $40 replacement | $180 to $280 in fuel and oil |
| Chain and bar oil | $60 to $100 | $60 to $100 |
| Maintenance (carburetor, plug, filter) | $0 | $60 to $150 |
| Replacement chains | $40 to $80 | $40 to $80 |
| 5-year total (typical homeowner) | $440 to $640 | $520 to $1,010 |
For a homeowner using the saw a dozen times a year, battery usually comes out cheaper and simpler over five years. For a heavy user running a saw weekly, the fuel line in the gas column keeps growing, but so does the cost of battery replacements, which tends to equalize things.
Noise, Weight, and Maintenance
Noise
A battery chainsaw under load typically measures 85 to 95 dB at the operator. A gas chainsaw is regularly 100 to 110 dB. That difference matters: hearing protection is mandatory on gas and recommended on battery. For neighborhood cutting, battery is easier on everyone within earshot.
Weight
A 14 to 16-inch battery chainsaw with battery weighs 9 to 12 pounds. A comparable gas chainsaw is usually 10 to 13 pounds. The weight is similar, but gas saws often carry theirs higher at the head, which changes how the saw handles in a long cut.
Maintenance
Battery chainsaws need chain tension, chain sharpening, and bar oil. That is essentially the entire list. Gas chainsaws add fuel mixing, carburetor tuning, air filter cleaning, spark plug replacement, and muffler screen maintenance. For someone who cuts a few times a year, the gas maintenance list is the most common reason a saw fails to start when you need it.
Which Should You Buy?
Homeowner with a suburban yard and occasional storm cleanup
A battery chainsaw with a 12 to 16-inch bar is the right tool, and you will use it far more often because it is easy to grab. The Wild Badger 20V 12-inch cordless chainsaw is the natural fit for pruning, light firewood, and post-storm limbing. Step up to the Wild Badger 40V 16-inch cordless chainsaw if you want more bar length for bucking firewood or taking down small trees yourself.
Cabin owner or rural homeowner cutting seasonal firewood
A 40V battery chainsaw with a 16-inch bar and two batteries is now a realistic primary saw for this use case. Keep a gas saw as a backup for the rare 20-inch log. See the full lineup on the Wild Badger cordless chainsaw collection, and plan on adding a spare 40V battery so one pack can charge while the other is on the saw.
Heavy user or small acreage owner
If you cut every weekend and your trees are large, a gas chainsaw in the 50 to 60cc class still pays for itself in runtime. Pair it with a small battery saw for limbing and cleanup, where the battery unit is dramatically more comfortable. The Wild Badger 20V compact saw is the easier companion to keep near the woodpile for quick jobs.
Professional tree work
Gas still leads in this category, but top-tier battery saws are now seen on professional jobs for urban and noise-restricted sites.
Common Questions
Is a battery chainsaw powerful enough to cut firewood?
Yes, for firewood in the 4 to 12-inch range a modern 40V or 60V battery chainsaw handles it comfortably. An 80V battery saw extends the comfortable range to roughly 16 inches. Logs above that are still faster with a gas saw.
How long does a battery chainsaw run on one charge?
Expect 20 to 50 minutes of intermittent cutting on a full charge, depending on the battery size and the wood. That usually translates to 30 to 80 typical homeowner cuts. Continuous heavy cutting drops the runtime toward the low end.
Is gas still better for big trees?
For logs over 16 inches and for all-day cutting, yes. Gas chainsaws hold sustained torque better under heavy load and refuel faster than a battery can recharge. For most other work, the gap has closed.
Do battery chainsaws need bar oil?
Yes. Every chainsaw, gas or battery, needs bar and chain oil to lubricate the chain as it runs. The oil keeps the chain cool, reduces friction, and extends chain life. Skipping it damages the bar and chain quickly.
Are battery chainsaws safer than gas?
They are safer in small ways. Lower noise reduces fatigue, no fuel handling reduces fire and burn risk, and instant on-off is more predictable. The blade itself is the same danger in both tools. Kickback protection, chaps, and gloves matter regardless of power source.
The Bottom Line
Battery chainsaws are now the right choice for most homeowners. Quieter, cleaner, simpler, and powerful enough to handle the bulk of cutting work a typical property needs. Gas chainsaws still own the long-session and big-log categories, and they remain the standard for professional heavy cutting.
Pick the saw that matches your actual cutting pattern. A battery saw you grab once a month beats a gas saw you never get to start because the carb is gummed up. And a gas saw that clears an acre in an afternoon beats a battery saw that strands you halfway through on a dead pack. If battery is the right match for your property, compare the Wild Badger cordless chainsaw collection to match bar length and battery capacity to the work you actually do.
