Greenworks PRO 80V 4.0Ah Lithium-Ion Battery ((Genuine Greenworks Battery / 75+ Compatible Tools)

Likes: Fair price, good performance, no cords, no gas. Dislikes: Charge time Currently using the 4 AH battery in the 80V Greenworks Pro leaf blower. Also have the 80V String Trimmer and expect awesome performance with that tool next spring. Leaf blower runtime with 4 AH battery: 35 minutes (at 85 degrees F outside temp) Used the "boost" button for maybe 60 seconds total. Comparison: Using 2.5 AH 80V battery, same conditions, got 17 minutes run time. On a 40 degree F day, 2.5 AH battery ran 23 minutes so expect even more run time from the 4 amp battery as the temps drop again. The 2.5 AH battery runs for 30-40 minutes in warmer weather with the string trimmer, depending on how thick the weeds are. I expect 60-70 runtime with the 4 AH battery on the string trimmer. Charge time 4 AH: From fully depleted to full charge, about 50-55 minutes. The 2.5 AH charges in about 25 minutes for comparison. I actually think that's a better runtime to charge time ratio. I just purchased a second 2.5 AH battery because the runtime to charge time ratio is better. I might have to swap them frequently, but there will always be one fully charged by the time one runs out. You might think that sounds like a hassle but compare swapping a battery to mixing oil and fuel, pull starts, or dragging a cord around the yard. You will not be disappointed with Greenworks 80V batteries.

Very happy with this battery purchase. It definitely has much more power storage than the original 80V 2.0 Ah batteries and works really well. Fits the original charger without any problem and pops into our lawnmower without any issue. (The cover still closes). Be aware though that it is definitely a few inches longer than the original batteries. This could affect balance on certain shoulder/hand held items such as weed eaters. For lawnmowers and snowblowers though it's definitely a great upgrade.

We have a 40V push mower and bought this as a replacement battery. I was concerned when it arrived as it is longer than their standard 80V battery. It still fits inside the battery holder of the mower just fine and we are looking forward to the extra capacity of this battery. Went with the Greenworks name brand battery after reading some the disappointed reviews of the after market batteries. This is a great battery for stationary equipment like the mower. It is also quite a bit heavier so I don't think I would use it in a tool you have to carry like a weed wacker or blower.

I use this as a backup battery for the Greenworks Leaf Blower 80V/ 170MPH/ 730CFM which I can’t review here bc I didn’t buy it on Amazon. But the blower and battery are awesome. I got the blower as a Costco special that came with the battery and charger and then bought this to have charging while I use the other one. I have no less than 20 mature white oak trees on half an acre and this pair has cut my yard work in half in terms of time and labor. The blower will move anything you need, wet or dry; leaves, sticks, cats, raccoons, small children. I think this battery actually lasts longer than the one the leaf blower came with from Costco even though the specs said it has a shorter run time. As for the people complaining that the blower was too heavy with the battery, idk what they’re on about unless they’re 5’ tall or elderly. I’m a 5’9 woman not in the best shape and I can carry that thing around for hours. My moms purse weighed more and I used to have to pack that around for her in the mall. Anyway, very happy with the battery. 5 stars.
