Best Greenworks 40V 16 in Cordless Electric
As an Amazon Associate we earn from qualifying purchases.
If you searched for best greenworks 40v 16 in cordless electric, the product in this listing is a chainsaw, not a mower or trimmer. It is the Greenworks 40V 16-inch cordless electric chainsaw, model CS40L02. The Amazon listing sells it as tool only and says the battery and charger are not included, so a 40V battery and charger must be bought separately before the saw can run. This page covers what the listing says, what it leaves unstated, and the cutting jobs it is described for.
Quick answer
- The listing describes a 16-inch, battery-powered chainsaw, model CS40L02, with a mechanical chain brake and an automatic oiler.
- The saw is listed as tool only. The battery and charger are not included. The included items are the chainsaw, a scabbard and the operator’s manual.
- Its one runtime figure is a cut count, not a time: up to 100 cuts on 4×4 lumber on a single charge, with no battery size named.
- Buy it only if you already have a 40V battery and charger and you need a 16-inch saw for limbing, firewood and storm cleanup.

What the listed features do
The listing’s bullets describe a short list of features. The mechanical chain brake is described as adding safety and reducing the risk of injury. The automatic oiler delivers chain lubrication, which the listing says increases productivity. Pro style tensioning is described as making bar and chain maintenance easier. Push button start replaces a pull cord, and the listing says the saw has no starter rope.
The listing also says the brushless motor gives “2x more torque,” and that it provides more power and longer runtimes. Those are comparative claims. The listing does not name the baseline it compares against, so treat the 2x figure as the listing’s claim, not as a number you can compare with another saw from this page.
Taken together, most of the listed features are about convenience and chain care. The one safety feature the listing names is the chain brake, which is why the safety section below matters more than the feature list.
Who it suits
This saw suits a homeowner who already has a 40V battery and charger and wants a 16-inch cordless saw for limbing, cutting firewood and clearing storm debris. The listing’s highlight line names five uses: tree felling, firewood cutting, storm cleanup, limbing and pruning. Whether the saw is right for felling depends on the trunk sizes you work with, and the listing does not give those.
It also suits someone who wants to avoid fuel mixing, a carburetor and starter ropes. The listing says the saw has no gas, no carburetor, no spark plug and no starter rope, and that it starts with a push button. Those features are about convenience and upkeep. They do not change the kickback hazard described in the safety section below.
It also fits a yard where most of the work is at or below waist height. The listing says the saw has an automatic oiler and pro style tensioning, which it presents as easier bar and chain care. Those are the listing’s own words. It does not describe a chain maintenance schedule, so read the operator’s manual before the first cut.
Skip it if
Skip this listing if you need a saw that arrives ready to run. The listing says tool only, and the battery and charger are not among the included items. Add a battery and charger to your plan before you decide.
Skip it if most of your cutting is overhead. Penn State Extension advises against cutting above shoulder height, so for high limbs compare pole saws first.
Skip it if you need a runtime you can plan around. The listing’s cut count is tied to 4×4 lumber and no battery size, so it cannot be turned into a time or a cut count for your own work.
Skip it if a written warranty matters to your purchase. The listing does not state one.
Safe use before you start
A chainsaw is a different tool from a trimmer or a mower, and its main hazard is kickback. Oklahoma State University Extension explains that kickback occurs when the rotating chain hits a solid object or the chain is pinched in a cut. Its advice for storm cleanup applies to any saw: make sure the chain brake is on, and keep both hands on the saw.
Penn State Extension calls kickback a leading cause of chainsaw-related injuries. It says a chainsaw should be equipped with safety features such as a chain brake, throttle lock and anti-vibration systems. The listing names a mechanical chain brake. It does not say whether the saw has a throttle lock or an anti-vibration system, so read the full product page or ask the seller before you buy.
Penn State Extension also advises against cutting above shoulder height, because overhead cutting raises the risk of kickback and recoil. If most of your cuts are overhead, compare the EGO Power+ and Autubin pole saws and the Seesii and EGO Power+ pole saws before you settle on a chainsaw.
The same Penn State publication says a dull chain requires more force to cut and is more likely to cause kickbacks. The listing says the automatic oiler delivers chain lubrication. It does not say how the chain is sharpened or how often, so plan on the operator’s manual for chain care.
Oklahoma State University Extension recommends eye protection such as goggles or safety glasses with wrap-around lenses. Extension’s agricultural safety site recommends a full-face shield, or safety goggles or glasses with side shields, to protect the face from flying wood chips, twigs and sawdust. It also recommends holding the saw firmly with both hands using an encircling grip. The listing does not mention eye or face protection, so plan to bring your own.
The agricultural safety site describes a chain brake as a device that, when activated, stops the saw’s chain immediately if kickback occurs, and says that reduces the risk of injury. The same page describes chain brakes as a feature of gas chainsaws. Ask the seller how the brake on this battery saw engages before you buy.
What the listing does not say
The battery and charger are not included. The listing says tool only, and its included items are the chainsaw, the scabbard and the operator’s manual. Any battery and charger you run this saw with must be bought or already owned.
The listing gives no battery capacity, no battery model number and no runtime in minutes. Its cut count is a claim for 4×4 lumber, with no battery size named, so it does not tell you how long a battery lasts in your yard.
The listing does not state a warranty, a maximum trunk or limb diameter, a chain pitch, a bar model or a chain gauge. Its highlight line names tree felling, firewood cutting, storm cleanup, limbing and pruning as uses, but the bullets do not say what size of wood the saw handles.
The listing does not say whether the chain is a low-kickback design. Extension’s agricultural safety site says most consumer chainsaws are equipped with low-kickback chains or chains designed to have reduced kickback energy. That describes the category, not this model, so the listing is still silent on it. The horsepower field reads 3.6 with no unit or comparison given.
Before you buy: a short checklist
- Confirm you own a 40V battery and charger, or add them to the total cost of the saw.
- Ask the seller for the battery model number and capacity, since the listing names neither.
- Measure the thickest log or limb you plan to cut. The listing gives no diameter limit.
- Check whether the saw has a throttle lock and an anti-vibration system, since the listing names neither.
- Plan how you will cut high limbs, because overhead cutting carries the kickback risk described above.
- Keep the operator’s manual with the saw and follow its chain maintenance steps.
How we chose
This post covers one product: the Greenworks 40V 16-inch cordless electric chainsaw, ASIN B093GDNSCS, model CS40L02. It fits the keyword because the listing is a 16-inch, cordless, electric Greenworks 40V tool.
We kept this listing because it is a single saw with a full set of stated fields, including model number, chain length, weight and included items. We did not rank it against other chainsaws, and this post does not say it is the best option for any job.
The listing details come from a saved copy of the Amazon page, read on 2026-10-23. Only the title, bullets and specification fields from that copy are used. The safety points come from two university extension pages and one agricultural safety page, all opened on 2026-10-22. Every sourced fact here is tied to a quote from the saved listing or an opened page, and where a source is general, the post says so.
What we could not verify
We could not open the manufacturer’s pages for model CS40L02. The site refused the request, so the warranty, the battery platform, the runtime basis and the design of the chain brake are not confirmed beyond the listing.
We could not confirm which battery and charger the listing expects for this saw, or how long one charge lasts with a named battery.
The extension pages cover chainsaw safety in general. They do not describe this model’s controls, and they do not give a cutting capacity for it.
FAQ
Does the Greenworks 40V 16 inch chainsaw come with a battery?
No. The listing says tool only, and its included items are the chainsaw, a scabbard and the operator’s manual. Plan to use or buy a 40V battery and charger separately.
How long does one charge last?
Nothing in the listing converts its cut count into a time. The only figure is a number of cuts on 4×4 lumber, and the battery size behind that figure is not named.
Is a 16-inch chainsaw good for storm cleanup?
The listing names storm cleanup, limbing, firewood cutting, tree felling and pruning as uses. It does not state a maximum diameter, so check the size of the largest pieces you plan to cut before you buy.
Does this saw have a chain brake?
The listing describes a mechanical chain brake for added safety and reduced risk of injury. Oklahoma State University Extension says to make sure the chain brake is on and to keep both hands on the saw.
Is a battery chainsaw safer than a gas chainsaw?
The listing says the saw has no gas, carburetor, spark plug or starter rope. It does not compare its safety with gas models. Penn State Extension calls kickback a leading cause of chainsaw-related injuries, and that hazard applies to saws of any power source.
Should I use it for overhead limbs?
Penn State Extension advises against cutting above shoulder height, because overhead cutting increases the risk of kickback and recoil. For high limbs, compare pole saws before you buy a chainsaw.
Bottom line
Buy this saw only if you already own a 40V battery and charger and need a 16-inch cordless electric chainsaw for limbing, firewood and storm cleanup. Decision rule: if you do not already have a 40V battery and charger, skip this listing.
