Battery Stihl Chainsaw Review: Why EGO Power+ Wins

If you search “battery Stihl chainsaw” long enough, you will eventually hit a wall: Stihl does not sell through Amazon. Their battery lineup, including the well-regarded MSA 220 C-B and the compact MSA 140 C-B, is available in the US only through authorized dealers. For some people that’s fine. For people who buy tools online, compare prices in a browser tab, and don’t want to drive forty minutes to a dealer who may or may not have what they want in stock, that wall is real. This review covers what I’d actually buy in that situation. The EGO POWER+ CS1804 18” Battery Powered Chainsaw sits in the same performance class as the mid-range Stihl battery saws, ships to your door, and fits into one of the most practical battery ecosystems available to residential buyers right now.

If you’re building out a cordless tool setup from scratch, the ecosystem question matters more than any single tool. I’ve written about this across several pieces in Battery & Cordless Tools, and the short version is: the battery you already own is often worth more than a marginal spec advantage from a competing brand.

Quick Verdict

The EGO CS1804 is the battery chainsaw I’d recommend to most people maintaining a residential property with trees. It cuts with real authority, the 56V platform is genuinely useful if you already own other EGO tools, and the 18-inch bar handles most of what comes up in routine property maintenance: downed limbs, firewood, deadwood removal, the occasional tree taken down in sections. It is not a logging saw. Anyone who needs to work a saw hard for hours at a stretch should be looking at gas. But for the work most of us actually do, this saw is sufficient, and it costs less to run than you’d expect.

At the time of writing, the tool-only version runs around $230 on Amazon, and the kit with a 5Ah battery and charger is currently around $350. The EGO POWER+ CS1804 is consistently in stock, which I mention only because Stihl battery inventory at dealers can be patchy.

Key Specs

The CS1804 runs on EGO’s 56V ARC Lithium platform. The bar is 18 inches. The brushless motor is rated to deliver power comparable to a 40cc gas engine, which is roughly in the same territory as Stihl’s MSA 220 C-B. Chain speed is 6,900 feet per minute at peak. The saw includes a 3-second chain brake (it stops the chain within 3 seconds of trigger release), a tool-integrated chain tensioning system, and an automatic bar oiler with a translucent window so you can actually see the oil level without guessing.

Weight with a 5Ah battery installed is around 12.5 lbs. That’s heavier than the Stihl MSA 140 C-B, which comes in closer to 10 lbs with battery, but comparable to the MSA 220 C-B with its larger battery.

The 56V battery platform is shared across EGO’s full lineup. If you already own the EGO Hedge Trimmer with Battery and Charger, you’re already in the ecosystem and that 5Ah battery will run this saw without any additional purchase for the battery itself.

Performance and Testing

I’ve run this saw through two full seasons on my property. The work has included bucking up a large silver maple that came down in a storm (trunk sections up to 22 inches in diameter), seasonal cleanup of oak and ash limbs, and some selective deadwood removal in a mixed wood edge that borders my back field.

Cutting Power

For the maple work, I was making crosscuts through 18 to 22-inch sections. The saw handled these without laboring, though I was making two passes on the wider sections and letting the saw do the work rather than forcing it. (I timed this on a few cuts: a clean 20-inch crosscut through seasoned maple took roughly 14 seconds. Make of that what you will.) Compared to the Husqvarna 435 gas saw I was running before, the EGO is slightly slower on large-diameter cuts but within a range that I’d call acceptable for occasional use rather than production work.

On smaller diameter cuts, 6 to 10 inches, the saw is fast and responsive. This is the majority of the work I actually do, and for that it performs without reservation.

Battery Runtime

With a 5Ah battery, I’m getting roughly 45 minutes of active cutting on lighter work, less on sustained cuts through hardwood. For a morning session of mixed cleanup, I typically run through one battery and have enough left on a second to finish what I started. EGO’s 7.5Ah battery extends this noticeably, currently around $130 separately, and if your sessions run long I’d buy it alongside the saw rather than waiting.

The charging time on the standard charger is around 50 minutes for a 5Ah battery. EGO’s Rapid Charger gets that down to around 40 minutes. Not transformative, but useful if you only have one battery and need to turn it around mid-day.

Handling

The saw balances reasonably well. I have an average grip size and I found the handle geometry comfortable for horizontal and overhead cuts. The chain brake is crisp and the trigger response feels controlled rather than hair-trigger. My one complaint about handling is the chain tensioning system: it requires a scrench (the combination tool is included), and on rival saws like the Greenworks 80V Pro CS80L, tool-free tensioning is standard. This is not a dealbreaker, but if you’re someone who adjusts chain tension in the field regularly, it will register as a minor irritation. Which I realize is a specific complaint, but there it is.

The bar oil system works well. I went through a season and a half before I ran into any oiling issues, and those were self-inflicted (I let the reservoir run dry). The translucent window is genuinely useful here.

Noise and Fumes

This is worth stating plainly: the difference in noise between this saw and a comparable gas saw is large. Gas chainsaws run at 100 to 110 decibels. The CS1804 runs around 97 decibels with hearing protection still advisable, but the character of the noise is different. No exhaust, no choke, no fuel smell. If you’re cutting near a neighbor’s property line or working in the early morning, the battery saw is the more considerate choice without giving up meaningful performance.

Pros and Cons

What works:

• 18-inch bar handles the realistic range of residential tree work
• Brushless motor delivers cutting performance that’s competitive with mid-range gas saws for non-commercial use
• 56V battery platform shared with EGO’s full tool lineup, which makes every additional EGO tool cheaper to buy tool-only
• Genuine 3-second chain brake with responsive trigger
• Quiet enough to use in residential settings without complaints
• Bar oil window is a small thing that saves real frustration

What doesn’t:

• Chain tensioning requires a tool. Tool-free would be better.
• Not suited to sustained professional use or production logging
• Heavier than the compact Stihl MSA 140 C-B class of saw
• Bar oil cap can be stiff when cold

Who It’s For

This saw is for the residential property owner who needs a capable chainsaw for seasonal and storm cleanup, firewood preparation in modest quantities, and occasional selective cutting. If you’ve ever avoided tackling a downed limb because dragging out a gas saw felt like more production than the job warranted, this saw solves that. It starts instantly, requires no fuel mixing, and the entry cost is manageable.

It also makes the most obvious sense if you’re already invested in the EGO 56V platform. If you own the EGO Pole Hedge Trimmer or are building out a cordless setup that includes a blower (I’ve covered the 40V end of the battery blower market in my 40V Cordless Leaf Blower review, though EGO runs at 56V), the CS1804 adds chainsaw capability without adding a second battery chemistry to your shelf.

It’s not for professional arborists, not for anyone who needs to run a saw for three continuous hours, and not for people who want the lightest possible bar for overhead limb work. The Stihl MSA 140 C-B at around 10 lbs with battery is meaningfully lighter if that’s the priority, though you’ll need to buy it through a dealer and it costs more.

For online buyers who want a serious battery chainsaw from a brand with wide distribution and strong parts availability, the CS1804 is the practical answer. You can find more context on how it fits into a broader cordless tool setup in my Battery & Cordless Tools coverage.

Frequently Asked Questions

Is the EGO CS1804 a good substitute for the Stihl MSA 220 C-B?

For residential use, yes. Both saws run on 56V-class battery systems and deliver comparable cutting performance on standard property maintenance tasks. The Stihl MSA 220 C-B has slightly better fit and finish and tool-free chain tensioning, but costs more and is only available through Stihl dealers in the US. If you buy online, the EGO CS1804 is the practical equivalent and the ecosystem depth is, if anything, better.

What battery does the EGO CS1804 use?

The 56V ARC Lithium battery platform, shared across EGO’s full lineup of outdoor power equipment. The kit version includes a 5Ah battery. EGO also makes 2.5Ah, 4Ah, 7.5Ah, and 10Ah batteries on the same platform. All are backward and forward compatible with any EGO 56V tool.

How long does the battery last per charge?

On lighter work, plan for 40 to 50 minutes of active cutting from a 5Ah battery. On sustained hardwood work, expect closer to 30 to 35 minutes. A 7.5Ah battery, currently around $130 separately, extends those times by roughly 50 percent. For a morning session, two 5Ah batteries will cover most residential cleanup tasks.

Can the EGO CS1804 cut through a full-sized tree?

The 18-inch bar will handle a tree up to approximately 32 inches in diameter by cutting from both sides. In practice, most homeowners are dealing with trees in the 12 to 20-inch range, and the saw handles those without difficulty. For a full tree takedown rather than limb and storm work, make sure you have two charged batteries and a plan for the job before you start.

Does the EGO CS1804 require any maintenance beyond chain sharpening?

Regular maintenance covers chain tension checks (the chain stretches with use, especially when new), bar oil refills, and occasional bar groove cleaning. The chain and bar should be replaced on the same schedule as a comparable gas saw. EGO recommends using bar and chain oil rated for outdoor power equipment. There’s no air filter to clean, no carburetor to adjust, and no fuel system to deal with, which is most of what drives gas saw maintenance time.
