EGO CS2000 vs CS1800: Which One Should You Buy?

Both are cordless chainsaws designed around the EGO 56V battery platform. They differ in guide bar length and drive link count, with the CS2000 running a 20-inch bar with 69 drive links and the CS1800 running an 18-inch bar with 62 drive links. This comparison covers both platforms, then three concrete examples from the listings we reviewed.

EGO CS2000 vs CS1800: Bar Length and Cutting Capacity

The most immediate distinction between the EGO CS2000 and the CS1800 is guide bar length. The CS2000 platform features a 20-inch bar designed for clearing large branches, cutting stumps and felling trees. That extra length allows you to work through larger rounds in fewer passes. In contrast, the CS1800 platform uses an 18-inch bar suited for moderate firewood bucking and limb cleanup.

Because guide bar length determines chain length, the two platforms use incompatible chains. Listings for the CS2000 side specify 69 drive links, while listings for the CS1800 side specify 62 drive links. Both share a 3/8-inch pitch and a 0.050-inch gauge, but the link count prevents swapping chains between them.

Chain Speed and Motor Output

Stated motor output and chain speed can help define cutting performance when both listings provide those figures. For the CS2000, the EGO listing states a brushless motor delivering power equivalent to a 55cc gas chainsaw, with chain speeds up to 25 m/s for clean cuts.

The reviewed CS1800 listing does not publish motor equivalent ratings or chain speeds for the CS1800 saw body, as it represents a replacement chain rather than a complete powerhead. Because our review relies strictly on what the listings state, the data leaves motor power and chain speed on the CS1800 side unstated rather than establishing a measured difference.

Chain Pitch, Gauge and Cutter Profiles

Both platforms use chains with a 3/8-inch pitch (specified as low profile on the replacement chain listings) and a 0.050-inch gauge. Across the reviewed listings, cutter specifications vary. The EGO CS2000 saw listing comes equipped with a full chisel tooth chain designed for taking down branches, stumps and tall trees. For replacement chains on the CS2000 side, the SawWorks example uses semi-chisel cutters made from German steel with Japanese chrome-plating, meeting the kickback performance requirements of ANSI B175.1-2012 and CSA Standard Z62.3.

On the CS1800 side, the reviewed AC1800 chain listing describes a low profile chain with low-kickback, low-backlash and low-vibration design, built from German steel with heat-treated rivets. Unlike the SawWorks listing, the AC1800 listing does not name ANSI or CSA standard certifications, and its spec table records chain type simply as Low Profile without specifying whether the cutters are semi-chisel or full chisel.

Battery Compatibility and Run Time

Both chainsaws run on the EGO 56V ARC Lithium battery system. The CS2000 listing indicates compatibility with all 56V ARC Lithium packs and recommends a 6.0Ah battery. According to the maker, a 6.0Ah battery delivers up to 135 cuts on 6×6 lumber on a single charge. The tool listing reviewed here is sold as a bare tool, meaning the battery and charger are available separately.

The CS1800 chain listing does not state run time or cuts per charge for the CS1800 powerhead. For anyone already invested in the EGO 56V ecosystem, batteries can be shared across outdoor power tools, but buyers starting fresh must account for battery and charger purchases.

Upkeep and Chain Maintenance

Maintaining both saws involves bar and chain care rather than engine tune-ups. Neither saw requires fuel mixing, spark plug changes or carburetor adjustments. Upkeep focuses on chain tensioning, bar oil management and keeping cutters sharp. The AC1800 chain listing notes automatic lubrication support to maintain bar and chain cooling.

The CS2000 bare tool weighs a listed 12.7 pounds and measures 39.76 x 11.22 x 12.6 inches, featuring a front LED work light and IPX4-rated weather resistance. The CS1800 saw weight is not stated in the reviewed listings. Safe handling requires full personal protective equipment: wear chainsaw chaps, a helmet with a face shield and hearing protection, non-slip gloves and sturdy boots. Never cut alone, and heed OSHA logging eTool safety practices.

Frequently Asked Questions

Which is better, the EGO CS2000 or CS1800?

Neither is universally better. The CS2000 platform provides a 20-inch bar with 69 drive links for cutting larger timber, and its saw listing specifies a 55cc gas equivalent motor and 25 m/s chain speed. The CS1800 platform uses an 18-inch bar with 62 drive links, making it the choice for mid-sized cutting where a 20-inch bar is unnecessary. The reviewed CS1800 listing leaves saw motor power and chain speed unstated.

Can the CS1800 use a 20-inch chain?

No. The CS1800 requires an 18-inch chain with 62 drive links in a 3/8-inch low profile pitch and 0.050-inch gauge. A 20-inch chain designed for the CS2000 uses 69 drive links and will not fit the 18-inch guide bar.

What batteries work with the EGO CS2000?

The CS2000 listing states compatibility with all EGO 56V ARC Lithium batteries. The maker recommends a 6.0Ah battery pack, which is rated for up to 135 cuts on 6×6 lumber per charge.

What safety gear is needed when operating these cordless chainsaws?

Always follow OSHA logging eTool safety guidelines by wearing chainsaw chaps, a forestry helmet with a face screen and hearing protection, heavy gloves and protective boots. Never cut alone, and maintain a secure stance to control against kickback.

Are the replacement chains for these saws low kickback?

The SawWorks 20-inch chain states compliance with ANSI B175.1-2012 and CSA Standard Z62.3 low-kickback requirements. The AC1800 chain listing describes a low-kickback, low-vibration design, though it does not cite a specific standard. The bare CS2000 saw includes a full chisel chain from the factory.
