Best Battery Chainsaws in 2027

This saw leads our ranking. It lists 2000 W of power output, the top figure on the page, shared with the Seesii M16 Ace. Power output is how hard the motor can push the chain through wood. For storm cleanup and logs near the bar size, that headroom helps the chain keep its speed. The 16 in bar ties for the longest on the page.

Battery energy is 200 Wh, the highest of the models that list it. That is the fuel tank of a cordless saw, so more watt-hours means more cuts before you stop. The listing also gives a chain speed of 25 m/s and says the brushless motor gives power equal to a 50CC gas engine.

At 9.2 lb it is not light, but it is lighter than the 10.3 lb Seesii M16 Ace and the 10.36 lb Greenworks 20312. It has a chain brake and an automatic oiler. The listing also mentions side-access tensioning for easier bar and chain upkeep. The maker does not publish a warranty term.

Think of this as a pruning tool, not a firewood saw. It weighs 3.2 lb, the lightest on the page, so long trimming sessions are less tiring. The 8 in bar and 7.5 in max cutting diameter keep it to branches and small logs. Compared with the 16 in saws, it trades reach for easy handling. Large trees need a bigger saw.

Power output is 1000 W, half of the 2000 W top figure on the page. That is enough for light work at a short bar length. The listing says it comes with two 4000 mAh batteries, which means you can swap one in when the first runs down. The maker does not list battery energy in Wh.

It has an automatic oiler and a 2-year warranty. The specs do not list a chain brake, so check the listing for safety features before you buy. Listing extras include tool-free chain tensioning, a spare chain, gloves and goggles. It ranks second on our list, but its small size limits it as a main saw.

The M16 Ace ranks third. Its power output is 2000 W, level with the Greenworks 80V at the top of the page. With a 16 in bar, it suits firewood and storm cleanup. The listing compares its efficiency to a 42cc gas saw, which gives a rough feel for the size of job it targets.

Battery energy is 160 Wh, below the 200 Wh of the Greenworks 80V. That number is the amount of work stored per charge, so it sets how long you cut. The listing gives up to 90 minutes of runtime from two 40V 4.0Ah batteries and a fast charger. Those batteries fit 40V tools only, not 20V ones, so check what you already own.

Weight is 10.3 lb, a bit heavier than the 9.2 lb Greenworks 80V and the 9 lb EGO. It has a chain brake and an automatic oiler with a 150ml reservoir. Chain tension adjusts without tools. The listing notes a cutting speed of 34.8ft/s. The maker does not publish a warranty term.

At 9 lb, the EGO is the lightest of the four 16 in saws on this page. It ranks fourth on our list. Weight matters because you hold the saw through every cut. Less weight means less strain on your arms and back over a long afternoon of limbing and cleanup.

The maker does not publish power output for this model, so motor strength is harder to compare. Without that number, the gas-equivalent claim is the main hint of cutting strength. The listing calls it a 40CC gas equivalent with a chain speed of 20m/s. Battery energy is 140 Wh, below the 160 Wh and 200 Wh on the other 16 in saws that list it. The listing claims up to 130 cuts on a 4 × 4.

The warranty is 5 years, tied for the longest on the page with the Skil. It has a chain brake and an automatic oiler. The listing adds tool-free chain tensioning and IPX4 weather-resistant construction. Weather resistance helps if you cut outdoors in damp conditions.

This 40V saw lists 1500 W of power output, below the 2000 W of the two leaders but well above the 1000 W mini saws. It pairs that with a 16 in bar and 160 Wh of battery energy, the same as the Seesii M16 Ace. It ranks fifth on our list.

Be careful with the cutting claim. The listing says it handles trees and limbs up to 28 in across, which is far larger than its 16 in bar. A bar that size cannot cut through a 28 in trunk in one pass. Treat the 28 in figure as a stretch and plan around the bar length. Use the 16 in bar as your real limit.

Weight is 10.36 lb, the heaviest 16 in saw here, though not the heaviest overall. At that weight, expect fatigue during long overhead work. It has a chain brake and an automatic oiler, and the listing adds tool-free tensioning. The warranty is 3 years for tool and battery.
