Amazon is offering discounts across some Greenworks batteries, so you can stock up your arsenal for guaranteed power when you need it. Among the models we’re seeing, the most notable is the brand’s G-MAX 40V 5.0Ah Battery for $125.99 shipped, with the price also matching direct from Greenworks’ website. This upgraded model normally fetches $180 at full price, with two previous discounts in 2025 taking things lower than ever to this same rate. You’re getting another shot at the lowest price we have tracked on this model, helping you stock up while saving you $54 off the going rate.
Greenworks is one of the best beginner-friendly electric lawn care solutions to replace gas-guzzlers, especially considering that its batteries work across multiple tools and even EVs. For those with an arsenal of 40V tools and devices, this battery is the second-largest for that particular ecosystem, only beaten in capacity by its 8.0Ah counterpart. It comes designed with multiple protections against overheating, short circuiting, over voltage, over current, over discharging, over charging, and more – plus, there’s even an LED indicator that gives you at-a-glance battery levels.
Other Greenworks batteries seeing discounts:
- 40V 2.5Ah Battery: $68 (Reg. $100)
- 80V Gen 2 2.0Ah Battery: $149 (Reg. $160)
- 80V Gen 2 5.0Ah Battery: $240 (Reg. $300)
