A cordless chainsaw is a portable, battery-powered alternative to gasoline-powered or corded electric chainsaws. Cordless chainsaws provide freedom of movement and convenience, allowing you to lift and maneuver the saw easily with one hand. However, cordless chainsaws have less power compared to gasoline models.

When selecting a cordless chainsaw, you’ll want to consider key factors like power, battery life, safety features, and ease of use to find the right fit for your cutting needs.

This guide will walk you through what to look for when choosing the best cordless chainsaw.

Battery Capacity

A cordless chainsaw is only as capable as its battery. Pay attention to the voltage and amp hour (Ah) rating to determine how long the chainsaw will run on a single charge. Higher voltage generally indicates more cutting power, while amp hours relate to runtime.

For occasional small jobs, a lower capacity battery around 20V to 40V and 2Ah to 4Ah may suffice. For frequent cutting sessions or thicker branches, look for a high capacity 40V to 80V battery with 6Ah or higher to handle the workload without frequent recharging.

Also consider the battery technology. Lithium-ion batteries provide sustained power output, are lightweight, and have no memory effect for optimal recharging. Brushless motors are also more efficient to extend runtime.

Bar Length

The bar length of a chainsaw determines the maximum diameter of material it can cut. Cordless chainsaw bars typically range from 10 inches to 16 inches.

Choose the shortest bar that still allows you to cut your intended branches or small trees to optimise portability, speed, and control. For example, a 10 inch bar can cut branches up to 10 inches thick.

Longer bars become heavy and are best for infrequent large cuts. Shorter bars tire the arms less but limit cut capacity. Get the right bar length suited to your expected tasks.

Power and Performance

While convenient, cordless chainsaws cannot match the raw power of gas chainsaws. However, models from reputable brands like Ego, Ryobi, Greenworks, or DeWalt now deliver suitable performance for common residential cutting needs.

Pay attention to the torque, chain speed, and cuts per charge ratings to gauge real-world cutting capability so you’re not frustrated or overwhelmed mid-job.

Higher power models may cost more but can blaze through projects other units would struggle with. Don’t underestimate your workload and buy more power than you expect to need for efficient, reliable cutting.

Safety Features

As power tools containing fast moving blades, chainsaws require adequate safety considerations. Here are key safety features to have:

Chain Brake: Stops the chain immediately if kickback occurs for added protection.

Low-Kickback Chain: Specially designed to reduce dangerous kickbacks when cutting.

Guards: Covers the top and sides of the bar when not sawing for safety.

Vibration Dampening: Reduces strain on your hands during extended use.

Don’t operate any chainsaw without protective eyewear, hearing protection, thick boots, and cut-resistant leg chaps or pants. Also maintain the chain regularly for optimal safety and performance.

Ease of Use

A final factor to weigh is the ergonomics and convenience features that can simplify operation:

Tool-free Chain Tensioning: Allows adjusting chain tension without additional tools for proper tautness.

Automatic Oiling System: Oils the chain continually to reduce wear and tear.

Compact Size: Choose a lightweight, balanced model for easy maneuverability in tight spots.

Battery & Charger Included: Opt for models including batteries and a charger for out-of-the-box functionality.

Brushless Motor: Provides high efficiency with less noise and vibration.

By carefully evaluating battery power, cutting capacity, safety protections, and ease of handling, you can select an optimal cordless chainsaw matched to your needs as a homeowner or professional.

Investing in the right model the first time prevents underpowered tools that compromise safety or become quickly obsolete. With a capable cordless chainsaw from a trusted brand, you can achieve clean, efficient cuts anywhere needed.
