8 Best Ryobi Battery 40v 2026 in the United States

The RYOBI 40-Volt Lithium-Ion Cordless Attachment Capable String Trimmer is a versatile garden tool that stands out for its compatibility with various attachments, enabling users to save time and space. The 4.0 Ah battery ensures decent run time and is a significant strength, along with the included 90-minute charger, which is fairly quick in recharging the battery.

The adjustable cutting width from 13 to 15 inches is another highlight, offering flexibility based on the task at hand. The variable speed trigger is a useful feature for controlling cutting speed, and the Reel-easy bump-feed string head simplifies reloading of the string, enhancing user convenience. Weighing 13.77 pounds, it is relatively easy to handle for a battery-powered trimmer. However, its weight could be a drawback for some users, particularly during extended use.

The requirement for assembly might also be a slight inconvenience for those who prefer ready-to-use tools. This trimmer is best suited for users seeking a reliable and versatile tool for their yard that can handle various tasks through attachment capabilities, particularly those who appreciate the convenience of cordless operation.

The RYOBI 16-inch 40-Volt brushless cordless chainsaw is a solid choice for homeowners or hobbyists looking for a lightweight and easy-to-use tool. Weighing about 11.4 pounds, it’s lighter than many gas-powered chainsaws, making it easier to handle during tasks like trimming trees or cutting firewood. The 40-volt battery system offers decent power with a 1.2 horsepower motor, which should be enough for medium-duty cutting jobs. However, the product is sold as 'tool only,' so you will need to buy the battery and charger separately, which adds to the initial cost. Ryobi’s 40V batteries usually provide good runtime and reasonable charging speed, especially if you already own compatible batteries from other Ryobi tools.

This chainsaw features a 16-inch chain length, a common size that balances cutting capacity and control for everyday yard work. Durability appears reliable, supported by positive customer reviews averaging 4.4 out of 5 stars, though it’s best suited for occasional use rather than heavy professional logging. Ryobi typically offers standard coverage for their power tools, which offers some peace of mind.

If you’re looking for a quieter, low-maintenance alternative to gas chainsaws and already have or plan to invest in Ryobi 40V batteries, this model can be a convenient and efficient option. Just be prepared for the extra purchase of batteries and charger if this is your first Ryobi cordless tool.

The Ryobi OP4030 40V 3Ah Battery Pack is designed for use with Ryobi 40V power tools, offering a reliable 3.0 amp-hour lithium-ion capacity. This capacity provides a decent runtime for a range of cordless tools, making it a good choice if you need moderate power for tasks like yard work or small home projects. Weighing about 3.1 pounds, the battery is relatively lightweight, which helps keep your tools easier to handle during extended use.

Compatibility-wise, it works with popular Ryobi chargers like the OP400 and OP401 (though these chargers are sold separately), and it replaces older models OP4015 and OP4026, so it fits well within Ryobi’s existing ecosystem. Customers generally rate this battery positively for its good performance and consistent power delivery.

This battery is a solid pick if you already use Ryobi 40V tools and want a dependable, moderately powered replacement or spare battery. Be sure to check your charger compatibility and consider how often you’ll need to recharge during your projects.
