Greenworks 40V 2.5Ah Lithium-Ion Battery - Reliable Yard Power

In this review the Greenworks 40V 2.5Ah Lithium-Ion Battery is evaluated for homeowners and weekend landscapers who need a dependable, interchangeable power source for a range of cordless tools. The bottom line: it delivers consistent power and fast charging for most routine yard tasks, and its compatibility with 75+ tools makes it a practical single-battery solution for mowing, trimming, and small cleanup jobs. Battery life reports are mixed, but when it performs as expected it provides enough capacity to complete typical yard work without swapping packs.

Key Features

• 40V GMAX chemistry: Provides steady power for Greenworks cordless mowers, trimmers, and blowers so tools run at expected performance levels.
• 2.5Ah capacity: Offers a balance of runtime and weight that lets users complete average lawn jobs without a bulky pack.
• Fast charge behavior: Customers note the pack charges quickly and does not overheat, reducing downtime between tasks.
• Lightweight design: At about 0.93 kg packaged weight the battery is easy to handle, making swaps and storage simple.
• Broad compatibility: Works across 75+ Greenworks tools, allowing one battery to serve multiple yard machines.

Who It's For

This battery is best for homeowners with small to medium yards who already own Greenworks 40V tools or plan to buy several compatible tools and prefer a single rechargeable pack to rotate between mower, trimmer, and blower. It suits users who value quick charge times and a lightweight battery that does not add excessive heft to handheld tools.

Those with very large properties, heavy professional use, or who require consistently long runtimes may want higher capacity batteries or a backup pack, since a portion of users report declining capacity over time and mixed battery life experiences.
