Best Greenworks Batteries Review 2022

Greenworks has been producing outdoor power equipment and batteries since 2007. The company has quickly grown and now has offices around the world.

The company is known for its quality battery-powered tools and innovation. Greenworks batteries come in a range of sizes, and power ratings, from 24-volt to 80-volt. In this review, we look at two of their most popular varieties, the 40 volts, and the 80 volts ranges.

Greenworks Battery Buying Guide [4 Key Features]

Battery Size

The Greenworks lithium-ion batteries use the latest technology to pack the same power inside a smaller case. The same technology significantly reduces the weight of the battery, allowing you to work for longer. Ni-Cad batteries with similar power are much larger and heavier.


The higher the voltage rating, the more power, and torque the tool will have. Small electric screwdrivers are fine on 24 volt systems, but where more power is required, look at 40 or 80-volt power tools.


The amp-hour rating (Ah) is an indication of how long the battery will last. Using a power tool drawing 1 amp of current, a 2 Ah Greenworks battery will last approximately two hours. A 4Ah has more space available to store more energy, so it provides power to cordless tools for longer. 4Ah battery will provide power for twice as long as a 2Ah battery.

Charging time

There’s nothing worse than getting partway through a job and having a flat battery. You then have to wait while the battery recharges, which could take several hours for a large-capacity battery.

The charging time increases with the amp-hour capacity of the battery. Spare Greenworks batteries can be purchased in various sizes.

What is the difference between a 2.0 Ah battery and a 4.0 Ah battery?

The simple difference is that a 4Ah battery should last twice as long as a 4Ah battery. However, other factors may affect the runtime of the battery.

Can I use a 4ah battery instead of 2ah?

Yes, this is perfectly fine. So long as the battery has the same voltage rating, and is designed to fit, then it will increase the tool’s working time.

How long do Greenworks batteries last?

All rechargeable batteries have a finite working life, which will vary depending on how the battery is maintained. Greenworks batteries are built to high standards and come with a 2-year workmanship warranty. Greenworks batteries have a high charging cycle capacity, and most will last for up to 2,000 charges.

How long does Greenworks 40v battery last?

Many factors affect how long a Greenworks 40-volt battery will last. The main element is the amp-hour (Ah) capacity. For example, a power tool that uses 1 ampere of current, should run for around 2 hours with a 2Ah battery. With a 4Ah battery, it will last approximately 4 hours.

Are Greenworks 40v batteries interchangeable?

Yes, if they are designed for that particular tool. You can use any amp-hour rated 40-volt Greenworks battery if it was intended for that model of tool.

Is higher voltage better for cordless tools?

The short answer is yes. A higher battery voltage means the device has more power than a lower voltage tool. The higher voltage provides more torque and requires less current. This means the battery will work for longer. The trade-off is that larger batteries will be heavier.
