We bought a greenworks mower and wanted to have an extra battery on hand. Had to wait a bit for this to be available le but well worth it. Works great and charges restively quickly. Runs a long time. Very pleased with our mower and the replacement battery.

What a miserable experience with a miserable company. We've had four batteries now, and all have failed within 2-4 months. Greenworks will not stand by their 3-year warranty. That is complete b.s. My husband is chatting with their customer service who only offered a 10% discount to purchase a new $180 battery. This attempt to save the planet has turned into a nightmare.

I just bought a Greenworks mower and bought the extra battery thinking I would need it. I have a fairly good size front and back yards. And to boot the mower is self propelled and I was able to mow both the front and back yards before it stopped! Amazing! It has great battery life and easy to use.

Battery arrived, tried to charge it but the charger flashed red that it was defective. I called Greenworks customer service and they sent me a new one, no questions asked and at no cost to me. Good customer service!

I'm a big Greenworks 40max fan. I have a lot of the units in their line... pretty much everything but a mower (not a fan of that power up/power down depending on grass thickness feature). I've had a couple of 4ah batteries and a 2ah for a few years now. Perfect performance, no issues (although I agree they are a bit hard to pry out of a few of the tools I use them with). This 5ah is PERFECT for my brushless blower. Of everything I have (tiller, small string trimmer, heavy duty string trimmer, air compressor, 16" chainsaw, which is AWESOME, hedge trimmer, also awesome, pole saw, and probably a couple I'm forgetting), the blower is the only battery hog. The battery use of each of these is VERY different, and that might be the cause of various reviews that go from 'lasts forever' to 'runs down quick;y' in all the Greenworks battery reviews.With my blower set on the turbo setting, which results in about 80% of the performance of a medium powered gas blower, you will only get about 12 or so minutes at full turbo blast setting and about 20 minutes on full/regular with the 4ah. As a comparison, I get almost a summer's worth of string trimming from a single charge on the smaller 2ah.Just gave the 5ah a run at full turbo power with the blower (it's again the powerful brushless model). Wonderful. I cranked it for 15 minutes on turbo and still had two lights.Very happy with the purchase and the whole line of productsl. Getting a significant price deal on the lightning offer on prime day didn't hurt either.For context, my yard is normal city size, with a lot of edging and blowing to do (deep lot with 140 foot driveway), so I say that I'm right about in the middle of the range for urban/suburban lawns. Plenty of power and battery life for everything I want to do, and now have meaningfully more time with the blower for the Fall leaf cleanup.
