  1. 12″+16″ 2-in-1 Brushless Cordless Chainsaw Compatible with Milwaukee M18

    12"+16" 2-in-1 Brushless Cordless Chainsaw Compatible with Milwaukee M18

    Best Versatile 2-in-1 Chainsaw for Flexible Cutting

    View on Amazon

    This chainsaw stands out for its dual-length design, allowing users to switch between 12-inch and 16-inch chains, making it highly adaptable for pruning, firewood, or larger cuts. The brushless motor provides longer runtime compared to brushed alternatives, such as the Brushless Electric Chainsaw for Milwaukee M18 18V, but the need for separate batteries means added cost and complexity. Its automatic oiling and safety features like rapid-stop brake prioritize operator safety and reduce maintenance, yet the requirement for Milwaukee M18 batteries limits its immediate usability for those without the compatible system. Compared to simpler, single-length models, this offers greater flexibility but at a higher price and dependency on additional batteries.

    Pros:
    • Versatile 2-in-1 design with two chain lengths
    • High-efficiency brushless motor for longer runtime
    • Automatic lubrication system reduces maintenance
    • Fast safety stop for operator protection
    Cons:
    • Battery and charger not included, additional purchase required
    • Requires Milwaukee M18 batteries for operation

    Best for: Professionals or serious DIYers needing a multi-purpose chainsaw with adjustable length for diverse tasks.

    Not ideal for: Casual users or those on a tight budget who prefer an all-in-one solution without extra battery purchases.

    • Chainsaw Lengths:12 inch and 16 inch
    • Number of Chains:4
    • Motor Type:Brushless
    • Cutting Speed:44.3 ft/s
    • Lubrication:Automatic oiling system
    • Battery Compatibility:Milwaukee M18
    Our verdict
    “This model suits experienced users who need flexibility and already own Milwaukee M18 batteries, but it’s less convenient for casual or budget-conscious buyers.”
  2. EGO POWER+ 18-Inch Battery-Powered Chainsaw (Battery & Charger Not Included)

    EGO POWER+ 18-Inch Battery-Powered Chainsaw (Battery & Charger Not Included)

    Best Power and Safety Features in an 18-Inch Model

    View on Amazon

    The EGO POWER+ 18-Inch Chainsaw offers a robust 2500W motor and a long 18-inch bar, making it a strong choice for heavy-duty cutting compared to smaller or less powerful models like the ONEAND 18V 6-inch Cordless Pruning Chainsaw. Its compatibility with EGO’s 56V ARC Lithium batteries provides flexibility, but the fact that batteries and chargers are sold separately can be a drawback for those seeking an all-in-one kit. The inclusion of safety features such as a safety brake and an LED work light enhances usability in various conditions, though its weight and size may challenge extended use. Compared to the Brushless Electric Chainsaw for Milwaukee M18 18V, it offers higher power but at potentially higher cost and larger form factor.

    Pros:
    • Powerful 2500W brushless motor for efficient cutting
    • Compatible with all EGO 56V batteries for flexibility
    • Safety brake and LED work light for versatile use
    • Tool-free chain tensioning for quick adjustments
    Cons:
    • Battery and charger sold separately, increasing total cost
    • Relatively heavy, which may cause fatigue

    Best for: Homeowners or professionals needing a powerful, versatile chainsaw with safety features and existing EGO batteries.

    Not ideal for: Light-duty users or those preferring a lightweight, all-in-one package with included batteries.

    • Motor Power:2500W
    • Bar Length:18 inches
    • Chain Gauge:0.50 inch
    • Drive Links:62
    • Weather Resistance:IPX4-rated
    • Warranty:5 years
    Our verdict
    “Ideal for users who already own EGO batteries and need serious power, but less suitable for those seeking a ready-to-go kit without extra purchases.”
  3. SEESII Mini Chainsaw 6 Inch Brushless, Automatic Oiler

    SEESII Mini Chainsaw 6 Inch Brushless, Automatic Oiler

    Best Compact Chainsaw for Precision Pruning and DIY

    View on Amazon

    The SEESII Mini Chainsaw excels in tight spaces and detailed pruning thanks to its small 6-inch blade, outperforming bulkier models like the 24-inch chainsaw for Milwaukee M18 18V Batteries when portability is key. Its brushless motor delivers surprisingly good power for a mini tool, and the automatic oiling system minimizes maintenance. However, its limited 6-inch capacity restricts it to small branches and pruning, making it unsuitable for larger tasks. The requirement for Makita 18V batteries and limited runtime may also be a concern for heavy or prolonged work. Compared to larger chainsaws, it sacrifices power for maneuverability, which is ideal for light-duty jobs.

    Pros:
    • Compact and lightweight for easy handling
    • Powerful brushless motor for a small tool
    • Automatic oiling system reduces maintenance
    • Durable impact-resistant metal cover
    Cons:
    • Requires compatible Makita 18V batteries, which may be extra
    • Limited to 6-inch cuts, not suitable for heavy-duty tasks

    Best for: Home gardeners or DIY enthusiasts focusing on pruning and small cutting jobs in tight or delicate areas.

    Not ideal for: Users needing to cut firewood or perform larger-scale yard clearing, due to its limited size and capacity.

    • Motor Power:1000W
    • Chain Speed:7.8 m/s
    • Chain Diameter:6 inches
    • Battery Capacity:2 × 2000 mAh
    • Runtime:up to 60 minutes
    • Compatibility:Makita 18V batteries
    Our verdict
    “Perfect for precise pruning and small cutting tasks, but not designed for substantial or heavy-duty cutting jobs.”
  4. ONEAND 18V 6-inch Cordless Compact Pruning Chainsaw (Tool Only)

    ONEAND 18V 6-inch Cordless Compact Pruning Chainsaw (Tool Only)

    Best Lightweight Pruning Chainsaw for Landscapers

    View on Amazon

    The ONEAND 18V 6-inch Chainsaw is designed specifically for pruning and small landscape projects, excelling in ease of use and portability. Its compact size and 6-inch blade make it more maneuverable than larger units like the EGO 18-Inch Chainsaw, though it sacrifices capacity for convenience. The tool-only design means users must have compatible batteries on hand, which could add to the overall cost if they lack existing Makita batteries. Its lightweight construction makes it ideal for quick, repetitive pruning but limits it to lighter tasks. Compared with larger models, it’s more about agility than raw power, and performance depends on the quality of the batteries used.

    Pros:
    • Lightweight and easy to handle
    • Cordless for maximum portability
    • Ideal for pruning and detailed trimming
    • Tool-only design allows flexibility with existing batteries
    Cons:
    • Limited to pruning, not suitable for heavy-duty cutting
    • Battery not included, additional purchase required

    Best for: Landscapers or homeowners who need a nimble, easy-to-handle pruning saw for small branches and trimming.

    Not ideal for: Users needing to cut larger branches or do firewood processing, due to its small size and limited capacity.

    • Voltage:18V
    • Blade Length:6 inches
    • Type:Cordless
    • Package:Tool only
    Our verdict
    “Best suited for quick, precise pruning in landscaping, but not for larger or more demanding cutting projects.”
  5. Brushless Electric Chainsaw 12″ Cordless Tool for Milwaukee M18 18V Battery

    Brushless Electric Chainsaw 12" Cordless Tool for Milwaukee M18 18V Battery

    Best Compact Power Chain for Milwaukee M18 Users

    View on Amazon

    The Brushless Electric Chainsaw for Milwaukee M18 18V offers a compact 12-inch blade with a powerful copper brushless motor, making it a solid choice for users already invested in Milwaukee’s ecosystem. Its 13 m/s chain speed rivals larger models, delivering quick cuts in a lightweight 5 lbs frame. Tool-free chain tensioning adds convenience, and the automatic oiler prolongs chain life. Compared to the 12″+16″ 2-in-1 Chainsaw, this model is less versatile but more straightforward, with fewer parts to manage. The main tradeoff is that it doesn’t include a battery or charger, which may increase total costs for new users. It’s best for those who want a dedicated, reliable tool within Milwaukee’s 18V system.

    Pros:
    • Powerful 1000W copper brushless motor
    • Lightweight (5 lbs) for easy handling
    • Quick chain tension adjustment without tools
    • Includes chains, gloves, storage bag, and protective cover
    Cons:
    • Battery and charger not included, additional expense
    • Limited to Milwaukee M18 18V batteries only

    Best for: Milwaukee M18 users seeking a compact, high-powered chainsaw for quick trimming and branch cutting.

    Not ideal for: Buyers without Milwaukee batteries or those needing a larger or more versatile tool for bigger jobs.

    • Motor:1000W pure copper brushless
    • Blade Length:12 inches
    • Chain Speed:13 m/s
    • Weight:5 lbs
    • Includes:2 chains, gloves, storage bag
    Our verdict
    “This chainsaw is a great fit for Milwaukee users wanting a compact, powerful option for light to medium tasks, but it’s less suitable for those without existing batteries or larger projects.”
  6. Mini Cordless Chainsaw Compatible with Milwaukee M18 18V Battery, 6 & 8 Inch Brushless Electric Chainsaw

    Mini Cordless Chainsaw Compatible with Milwaukee M18 18V Battery, 6 & 8 Inch Brushless Electric Chainsaw

    Best for Compact, Versatile Cutting Tasks

    View on Amazon
    This mini chainsaw stands out for its compatibility with Milwaukee M18 18V batteries, offering a cost-effective solution for users who already own M18 tools. Its lightweight design and multiple chains make it highly versatile for pruning and small cutting jobs. Compared to larger models like the Milwaukee 12-inch, this tool excels in maneuverability but isn’t suited for heavy-duty tasks. The brushless motor ensures efficient cuts, but the absence of an included battery and oil lubrication means additional purchases. Its compact size makes it ideal for tight spaces, though the limited cutting capacity restricts its use to lighter jobs. Overall, this pick makes the most sense for homeowners or professionals who need a portable, easy-to-handle saw for occasional pruning.
    Pros:
    • Compatible with existing Milwaukee M18 18V batteries, reducing extra costs
    • Includes multiple chains and guide bars for varied tasks
    • Lightweight and ergonomic for easy handling
    Cons:
    • Battery and oil lubrication not included, requiring additional purchases
    • Limited to small cutting tasks, not for heavy-duty use

    Best for: Homeowners or landscapers who want a lightweight, versatile chainsaw compatible with their existing Milwaukee M18 batteries

    Not ideal for: Heavy-duty contractors needing a saw for large tree felling or demanding construction projects, due to its small size and limited power

    • Battery Compatibility:Milwaukee M18 18V Batteries
    • Power:1200W
    • Chains:2 x 6-inch, 2 x 8-inch
    • Weight:2.7 lbs (tool only)
    • Motor:Brushless all-copper motor
    • No-load Speed:36 ft/s
    Our verdict
    “This chainsaw is best suited for users needing a compact, versatile tool for pruning and small cuts, especially those already invested in Milwaukee M18 batteries.”
  7. Makita XCU11Z 18V LXT Lithium-Ion Brushless Cordless 14-Inch Chain Saw, Tool Only

    Makita XCU11Z 18V LXT Lithium-Ion Brushless Cordless 14-Inch Chain Saw, Tool Only

    Best for Power and Precision in Cutting and Trimming

    View on Amazon
    The Makita XCU11Z offers a 14-inch guide bar, making it more capable for mid-sized cutting tasks than smaller saws like the RYOBI 8-inch. Its brushless motor delivers high torque with minimal noise and zero emissions, rivaling gas-powered models but with the convenience of cordless operation. Unlike the Milwaukee mini, this saw is better suited for demanding outdoor projects, though the need for compatible 18V LXT batteries and the higher price point may be a hurdle for some. Its tool-less chain adjustments and large oil window contribute to easier maintenance, but the absence of included batteries means additional investments. This model makes sense for professional landscapers or serious DIYers seeking a balance between power and portability.
    Pros:
    • High cutting speed and torque comparable to gas chainsaws
    • Tool-less chain adjustments simplify maintenance
    • Low noise and zero emissions for outdoor use
    Cons:
    • Batteries and charger are sold separately, increasing total cost
    • Higher price point than smaller, less powerful models

    Best for: Professionals or advanced DIYers needing a portable, high-performance chainsaw for medium-sized outdoor projects

    Not ideal for: Occasional users or those on a tight budget, as it requires separate battery purchases and has a higher upfront cost

    • Battery Voltage:18V
    • Guide Bar Length:14 inches
    • Cutting Speed:0-1,520 FPM
    • Battery Type:Lithium-Ion
    • Motor Type:Brushless
    • Application:Cutting and trimming outdoor wood
    Our verdict
    “This chainsaw works best for users needing a powerful, portable saw for demanding outdoor tasks who are willing to invest in high-quality batteries.”
  8. Cordless Mini Chainsaw 6 Inch for Makita 18V LXT (No Battery)

    Cordless Mini Chainsaw 6 Inch for Makita 18V LXT (No Battery)

    Best for Small, Precise Cutting and Pruning

    View on Amazon
    This 6-inch mini chainsaw is perfect for delicate pruning and small wood-cutting tasks, especially given its compatibility with Makita’s 18V batteries. Its compact size and lightweight design make it easy to control, especially for users who prefer one-handed operation. Compared with larger models like the Makita 14-inch, this saw sacrifices power for maneuverability, but safety features such as safety locks and anti-slip handles add to its appeal. The absence of a battery and its limited capacity mean it’s not suitable for heavy or prolonged use. This saw makes the most sense for homeowners or gardeners needing a portable, precise tool for trimming branches or small logs.
    Pros:
    • Compatible with Makita 18V batteries, offering flexibility
    • Lightweight and easy to handle, ideal for one-handed tasks
    • Efficient brushless motor for faster cuts
    Cons:
    • Battery not included, requiring separate purchase
    • Limited to small cutting tasks due to 6-inch blade

    Best for: Home gardeners or landscape professionals needing a lightweight, precise pruning tool

    Not ideal for: Users seeking a heavy-duty chainsaw for large logs or frequent, demanding use, due to its small blade and limited power

    • Compatibility:Makita 18V batteries
    • Blade Length:6 inches
    • Motor Type:Brushless
    • Battery Included:No
    • Safety Features:Security lock, safety baffles, anti-cut gloves
    • Included Accessories:Guide chains (x2), screwdriver, chainsaw file
    Our verdict
    “This mini chainsaw is best suited for those needing precise, light-duty pruning with the convenience of Makita’s battery system.”
  9. 12 Inch Cordless Chainsaw for Milwaukee M18 18V Batteries (Battery NOT Included) with 2 Replacement Chains

    12 Inch Cordless Chainsaw for Milwaukee M18 18V Batteries (Battery NOT Included) with 2 Replacement Chains

    Best for Larger Capacity, Heavy-Duty Outdoor Cutting

    View on Amazon
    The Milwaukee 12-inch chainsaw offers a robust brushless motor that handles bigger cutting jobs than the mini options, making it ideal for outdoor projects like felling small trees or clearing brush. Its inclusion of two replacement chains and an automatic oiling system enhances convenience and uptime. Compared to the smaller 6-inch Makita, this saw provides a longer bar for larger cuts but requires a larger investment and separate batteries, similar to the Makita 14-inch but with a focus on power. Its automatic features make maintenance easier, yet the need for additional batteries and the limited capacity (12-inch cut) restricts its use for very large trees. This model suits professional users or serious DIYers who prioritize power and capacity.
    Pros:
    • Powerful brushless motor for efficient cutting
    • Includes two replacement chains for extended use
    • Automatic chain tensioning and oiling for ease of operation
    Cons:
    • Batteries and charger sold separately, adding to cost
    • Limited to 12-inch capacity, not for very large trees

    Best for: Outdoor enthusiasts or professionals needing a powerful, medium-sized chainsaw for demanding tasks

    Not ideal for: Casual users or those limited by budget, since it requires separate batteries and is more expensive

    • Battery Compatibility:Milwaukee M18 18V Batteries
    • Chain Length:12 inches
    • Motor Type:Brushless
    • Includes:2 replacement chains
    • Oiling System:Automatic
    • Battery Included:No
    Our verdict
    “This chainsaw is ideal for users looking for a powerful, mid-sized outdoor saw who are prepared to invest in compatible batteries.”
  10. RYOBI 18V ONE+ 8-Inch Brushless Pruning Chainsaw Kit with Battery and Charger

    RYOBI 18V ONE+ 8-Inch Brushless Pruning Chainsaw Kit with Battery and Charger

    Best for Light Pruning and Branch Trimming

    View on Amazon
    The RYOBI 8-inch chainsaw is tailored for pruning and light limbing, with a brushless motor delivering cuts up to three times faster than traditional models. Its compact design allows access in tight spaces, making it a favorite for trimming branches or small logs. Compared with the Makita mini, this saw offers a slightly larger bar and the convenience of an included battery and charger, though it’s primarily designed for lighter tasks. Its limited capacity—up to 6-inch branches—means it’s not suitable for larger logs or heavy-duty cutting. This makes it perfect for homeowners or gardeners who want a quick, easy solution for routine pruning, especially those who prefer a ready-to-use package.
    Pros:
    • Includes battery and charger, offering ready-to-use convenience
    • Fast cutting with 3X faster speed than traditional models
    • Compact design for tight space access
    Cons:
    • Limited to branches up to 6 inches in diameter
    • Battery life may fluctuate with heavy use

    Best for: Homeowners or gardeners seeking a fast, lightweight saw for pruning and small branches

    Not ideal for: Users needing a saw for thick logs or large tree felling, due to its small bar and limited power

    • Voltage:18V
    • Bar Length:8 inches
    • Motor Type:Brushless
    • Battery Life:Over 65 cuts per charge
    • Application:Pruning and light limbing
    Our verdict
    “This chainsaw makes an excellent choice for light pruning and trimming tasks, especially for users who want a complete, ready-to-go kit.”

Factors to Consider When Choosing Chainsaw Battery 18v

Choosing the right 18V chainsaw battery involves more than just capacity. Several factors influence how well a battery will perform in your tools, affecting runtime, power delivery, and ease of use. Knowing what to prioritize can help you avoid common pitfalls, such as buying a battery that’s too small for your workload or incompatible with your chainsaw. Here are key considerations to keep in mind:

Battery Capacity and Runtime

Higher capacity batteries typically last longer, allowing for extended cutting sessions without frequent recharges. However, larger batteries tend to be heavier, which can impact maneuverability, especially during prolonged use. If your tasks involve quick pruning or light trimming, a smaller capacity battery might suffice, saving weight and cost. For heavy-duty cutting, investing in a larger capacity ensures you won’t be caught short mid-job, but be prepared for increased weight and price.

Compatibility and Brand Ecosystem

Most 18V batteries are designed to work with specific brands like Milwaukee, Makita, or RYOBI. Sticking within a brand ecosystem often provides better performance and easier compatibility with existing tools. Mixing brands can lead to compatibility issues, reduced performance, or voided warranties. Confirm that your chainsaw and batteries are compatible to avoid investing in batteries that won’t fit or deliver optimal power.

Weight and Ergonomics

Weight impacts user fatigue, especially during extended use. Compact, lightweight batteries are easier to handle but may deliver less runtime or power. Conversely, heavier batteries can support more demanding tasks but may cause fatigue. Consider your typical workload: for small pruning jobs or tight spaces, lighter batteries are preferable. For larger projects, a more substantial battery with better power output might be worth the extra weight.

Additional Features and Accessories

Features like automatic oilers, quick-charging capabilities, and included chains or safety features can enhance usability. Some batteries come with built-in LED indicators for remaining capacity, which help prevent unexpected power loss. Investing in kits that include batteries and chargers may offer better value, but check if the included accessories match your needs. Remember, more features often mean higher cost, so prioritize those that add real value for your specific tasks.

Cost and Value

Prices for 18V chainsaw batteries vary widely based on capacity, brand, and features. Cheaper batteries might save money upfront but could compromise runtime or durability over time. Premium batteries tend to last longer, charge faster, and perform more consistently, especially under demanding use. Balance your budget against your needs; for occasional light work, a less expensive option may suffice, but for frequent or heavy-duty use, investing in a higher-quality battery can save money in the long run.

Frequently Asked Questions

Can I use a different brand’s 18V battery with my chainsaw?

Using a battery from a different brand usually isn’t recommended unless it explicitly states compatibility. Most brands design their batteries and tools to work within specific ecosystems, ensuring optimal performance and safety. Attempting to fit a non-compatible battery can lead to poor power delivery, damage to the tool, or safety hazards. Always verify compatibility before trying to mix different brands or models.

How long does a fully charged 18V chainsaw battery last for cutting?

The runtime depends heavily on the battery’s capacity and the type of work. A typical 18V battery ranges from 2 to 5 amp-hours, offering anywhere from 15 minutes to over an hour of continuous cutting for light tasks. For heavier cuts or larger trees, expect shorter runtimes per charge. Always consider your workload size and choose a battery with sufficient capacity to avoid frequent recharges.

Is it worth buying an extra battery for my chainsaw?

Adding a second battery can significantly improve productivity, especially during large projects. It allows you to swap batteries when one runs out, minimizing downtime. For frequent or heavy-duty use, investing in an extra battery often pays off by maintaining steady work flow. However, if you only do occasional or light pruning, a single high-capacity battery might be enough.

Are brushless motors better than brushed ones for chainsaws?

Yes, brushless motors generally offer better efficiency, longer lifespan, and more consistent power output compared to brushed motors. They generate less heat, which improves durability, and often provide smoother operation. When paired with quality batteries, brushless chainsaws tend to perform better over time, especially under demanding conditions. This makes them a worthwhile investment for serious users.

What should I do if my battery doesn’t hold a charge?

If your 18V battery no longer holds a charge or discharges quickly, it might be aging or damaged. First, check if the charger and connections are functioning properly. If the battery is old or has been heavily used, replacing it may be the best option. Proper storage—keeping batteries in a cool, dry place—and avoiding complete discharges can extend their lifespan. If issues persist, consult the manufacturer or consider a warranty replacement.

Conclusion

For casual users or light pruning, a compact, affordable battery like the one included with the RYOBI 18V chainsaw offers excellent value and ease of use. Serious landscapers or those tackling larger projects should consider the Makita XCU11Z for its robust runtime and power, making it the best overall choice. Budget-conscious buyers can opt for dependable batteries from brands like Milwaukee or RYOBI, which balance performance and cost. Premium users seeking maximum durability and performance will find investing in higher-capacity batteries or kits with fast-charging features worthwhile. Ultimately, your specific needs—whether light maintenance or heavy-duty work—should guide your choice in this versatile category.
