Battery Chainsaws

How Does a Battery-Powered Chainsaw Work? (+ Review of 5 TOP Rated Picks)

Chainsaws have long been termed noisy and complex tools that need gas mixing, manual starts, cord management (electric models), and complicated maintenance problems. But thanks to technological innovations in the realm of battery-powered tools, chainsaws have become quiet, easy to manage, and operate.

What You Need to Know about Using a Chainsaw

Although battery-powered chainsaws are incredibly user-friendly, you still need to give them the respect they deserve. A chainsaw is one of the most dangerous unlicensed tools, and if not handled properly, it can cause severe injuries. A battery-powered chainsaw is an ideal tool for use in your backyard for pruning, cutting firebricks, bucking, and even felling (with heavy-duty models). All you have to do is slide in the charged battery, put in some lubrication oil, take safety precautions, and you are good to go. We will discuss the safety and usage guide in detail later in this article.

A chainsaw is one of the most valuable tools you can have around the yard. Battery-powered chainsaws are now competing with their gas and electric counterparts and are giving them quite a run for their money. Cordless chainsaws are quiet, easy to set up, super-fast while cutting, eco-friendly, and easy to maintain. They are also cheap, and you can use the batteries in other tools of the same brand. So, all in all, it is a win-win situation for you.

Battery-Powered Chainsaw Anatomy

To understand the working of a battery-powered chainsaw in detail, you must familiarize yourself with the various parts and components of the tool.

Battery: It is the fuel system on which the saw runs. The battery is inserted on the top side in most of the models.

Saw Chain: It is the part that does all the cutting. The efficacy of your tool depends on how maintained and sharp the chain is. It is also the most lethal part of the saw.

Guide Bar: It is the part where the chain moves. The guide bar and the chain must be oiled to ensure a frictionless platform.

Front Hand Guard/Chain Brake: Chain brake or front handguard is the most crucial safety feature on the chainsaw. It is used to stop the chain from moving around the guide bar. If your hand slips while using the saw, it will touch the chain brake, and the saw will stop automatically.

Oil Reservoir Cap and Oil Window: Oil reservoir cap is the entry point for the oil container. It is the place where you refill the oil. The window on the oil reservoir tells about the remaining oil.

Trigger Switch and Trigger Lock: The trigger switch is used to speed up the saw when the blade is running. The trigger lock is a safety lock. When engaged, it prevents the blade from spinning.

Rear Handle and Rear Guard: As the name implies, the rear handle and guard help the user to hold the tool securely and reduce the chances of an accident.

Side Covers: All the parts inside the tool are protected with side covers. You will need to remove the side cover for cleaning/maintenance of the internal components.

Battery Chainsaw Buying Guide

You don’t buy a tool like a chainsaw every other day. A chainsaw is a long-term investment that comes in handy for various tasks. What’s the point of having a tool which isn’t versatile, and you can’t use it for multiple jobs?

Most homeowners are unaware of all the features that impact the performance and overall life of the tool. They check the battery life and make the purchase. A lot of features other than battery runtime are also important.    

We want you to purchase the best battery-powered chainsaw according to your needs. Therefore we have created this buying guide and listed all the critical features you would like to have in your chainsaw.

Features to Consider before Buying a Battery-Powered Chainsaw

Battery: All the chainsaws come with a lithium-ion battery. When going through the battery details, there are four main things to consider.

Capacity: The battery capacity is determined by the Amp-hour rating of the battery. The larger the rating, the more powerful the battery is. So, make sure you buy a chainsaw with maximum battery capacity if you want it to work for extended hours.

Runtime: Runtime is the measure of how much longer a battery will run. The runtime will vary according to the nature of the work you are doing with a saw. Some brands mention how many cuts a chainsaw will make on a particular wood with a full battery. Here you need to consider the nature of the work and then decide how much runtime you want.

Recharging Time: It is always best to have a chainsaw with a low recharging time. Lithium-ion batteries usually take less time to recharge than their predecessors (Ni-CAD batteries). The recharging time also depends on how powerful your charger is.

Voltage: Batteries are also measured in voltages. A battery with a high voltage rating is more powerful than a low voltage battery. Chainsaw batteries have different ratings, such as 18V, 20V, 60V, or even 80V. Some saws use multiple batteries, while others use one battery.

Motor Type: Another important feature to consider is the motor type. There are two types of motor; brushless and standard. A brushless motor is better than a standard motor because it creates less friction. This, in turn, keeps the tool cool and provides a better runtime.

Oiling System: The oiling system consists of the oil reservoir, cap, and viewing window. The best arrangement would be a large reservoir with a tool-less opening mechanism and a viewing window.

Chain and Guide Bar Length: The length of the chain will decide the maximum width of the wood you can cut the saw. Chainsaws come in various sizes starting from 12, 14, 16 and go up to 18 inches. 18-inch models are rare in cordless chainsaws, but you can find a few models like the Greenworks chainsaw reviewed above.

Speed Mechanism: Some high-end models offer variable speed controls. A pressure-sensitive speed control regulates the chain speed. A variable speed chainsaw is better than a single-speed chainsaw because it allows you to work on different woods.

Handles: All chainsaws have two handles. Metallic handles are better than plastic handles because they offer more grip and stability while cutting wood. It is better to go with a rubberized handle with grip marks because it feels comfortable to hold and doesn’t tire you much after a long job.

Blade Guard: The blade guard is a crucial part of a chainsaw. Your safety depends on it. All the saws come with a blade guard. What you need to do is to make sure that it is properly working before cutting some wood.

Weight: The weight of the machine also affects its workability. If you are a homeowner and need a chainsaw for minor applications, go for a lightweight model.  

Warranty: Try to buy a battery-powered chainsaw with a maximum warranty period. The battery/charger may malfunction anytime due to exposure to water or any other issues. Hence, it is better to have an extended warranty to cover up such issues.

Safety Tips and Usage Guide for a Chainsaw

A chainsaw is one of the most dangerous tools you’ll ever handle. When working with your own gas-powered or battery-operated chainsaw, you need to ensure that all the safety precautions are taken before you get to work. Here we will discuss some safety tips and the operational guide for chainsaws.

Safety Tips

  • Make sure you go through the user manual before you start cutting with your tool.
  • Make sure you remove the battery whenever doing maintenance on the saw. Unlike a gasoline saw, a battery-powered chainsaw doesn’t require pull starting. Hence, it is best to remove the battery as mishaps can happen at any time.  
  • Never operate your tool with one hand. No matter how lightweight it is. If you are using one hand and the tool kickbacks, the automatic chain brake will not be engaged, and you can injure yourself.
  • Make sure that the chain is tightened correctly and lubricated to prevent overheating and binding.
  • You must check the oil level before starting a job and randomly check the oil level in the reservoir if you are working for extended hours.
  • A hard hat, safety goggles/face shield, hearing protection are a must.
  • You must wear heavy-duty work gloves with an enhanced grip surface, work boots with steel toes, and chains saw safety chaps to keep your legs safe.

Usage Guide

  • Keep a steady grip on the saw. Wrap your thumbs and fingers around the handles and hold the tool firmly.
  • Hold your saw close to the body when working in confined spots for better grip and balance.
  • Stand with your feet shoulder-width apart. Make sure you are well-balanced and be prepared to handle the kickback jerk from the saw.
  • Never operate a chainsaw with a curved back. Bend your knees when working in a low position.
  • The chain must be switched off when moving to other working positions. You must always stop the blade before placing the saw at one side and never turn on the saw when it is on the ground.
  • Keep your work partners or other people away from the saw. Maintain a safe distance of 4-6 meters.    
  • Keep your GPS active and share the location with someone responsible if you are going out for tree felling along.
  • Make sure you learn to handle the saw in the right way to avoid kickback.
