Choosing the best greenworks 18-Inch chainsaws requires comparing key specifications. We evaluated 4 models to help you find the right tool. Our top pick is the Greenworks 80V 18 in Cordless Chainsaw. It leads because its 2.5KW motor delivers gas-equivalent power. All selections are based strictly on published specs from the listings. This guide helps you decide which voltage and weight suit your limbing needs.
Match voltage to your runtime needs
You should choose your chainsaw based on the balance between voltage and battery capacity. Higher voltage models like the 82V and 80V offer more power for tough tasks. If you need longer runtime without frequent recharging, the 40V model with an 8.0 Ah battery is a better fit. All options provide an 18-inch clearing width for standard limbing jobs.

Choosing the Right Greenworks 18-Inch Chainsaw
Match Voltage to Power Needs
Voltage indicates the motor's potential power output. Higher voltage models deliver more torque for cutting thicker branches. The Greenworks 82V and 80V chainsaws offer the highest power levels for demanding tasks. If you need gas-equivalent performance, consider the 80V model with its 2.5KW motor. The 60V option provides a middle ground for users who need more power than 40V models. Choose the voltage that matches the density of the wood you plan to cut.
Check Battery Capacity for Runtime
Battery capacity, measured in Amp-hours (Ah), determines how long the chainsaw runs on a single charge. A higher Ah rating extends runtime but may add weight. The 40V model features an 8.0Ah battery, which prioritizes longevity over peak voltage. This makes it suitable for extended limbing sessions. Most other models use 4.0Ah batteries. If you cut frequently, a higher capacity ensures you finish jobs without interruption. Consider your typical workload size when selecting battery capacity.
Consider Weight for Maneuverability
Weight affects how easy the chainsaw is to handle overhead or for extended periods. Lighter tools reduce user fatigue. The 80V and 60V models weigh 9.48 pounds, offering a balance of power and manageability. The 82V model is slightly heavier at 9.7 pounds. The 40V model is significantly heavier at 15.7 pounds due to its larger battery. If you perform precise limbing or work in tight spaces, the lighter 80V or 60V options may be more comfortable to use.
Evaluate Motor Type for Efficiency
Brushless motors provide better efficiency and longer lifespan compared to brushed motors. They generate less heat and require less maintenance. The 60V and 82V models feature brushless technology, ensuring consistent power delivery. The 80V model includes a 2.5KW motor for high torque. The 82V model offers a 2.7KW output for serious clearing. Choosing a brushless model ensures you get reliable performance over time, especially if you use the tool for frequent professional or heavy-duty tasks.
Assess Physical Dimensions for Storage
The overall length and width determine how the chainsaw fits in your storage space. The 80V model is 35.4 inches long and 8.58 inches wide. The 60V and 82V models are longer at 37.5 inches. The 40V model has a different dimension profile with a height of 37.5 inches. Ensure your garage or shed has adequate space for the specific model you choose. Compact dimensions are helpful if you have limited storage. Compare the length and width to ensure the tool fits comfortably on your rack or hook.
