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

Awesome! It worked great! I used it today. I did the job and still had 2 bars left on my battery. Easy to use. Speed of charging is great. It fit in my 80 Volt green works lawn mower just fine. It was compatible. Weight is not too heavy. Very highly recommend! I love it!

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.

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.

Holds a charge very well and it was a great price

This battery was great for the first year, then it started to not hold the charge, and after 1.5 years it won't charge at all. We're extremely disappointed that we spent so much on a battery for only a year of expected functioning and then having to purchase a new battery after such a short period of time. We love our mower, but it is definitely getting too pricey if we have to purchase a new battery every year. We'll be rethinking our lawn mower choice, ugh! I'd only purchase this if you are ok with knowing you'll get a year out of it and will need to purchase one every year.

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.

I received this product on Dec 7, 2020. I was very excited as I had purchased a Pro 80V Green Works cordless lawn mower, Pro 80V 18 in cordless chainsaw, Pro 80V 16 inch cordless string trimmer, and Pro 80V cordless blower and two batteries a normal Pro 80V 2.0 A and the larger Pro 80V 4.0 A. I had thus sunk a lot of money in the green revolution and was excited about the equipment. As it was winter already, I have only used the blower. It worked great even if the batteries didn't last too long. I used the 4.0 A mostly because I got a good 30 minutes of max blowing with it. With the snow coming a week before Christmas, I put the battery and its charger in the heated basement (it had been upstairs and always indoors before) charged the batteries and then left them next to the charger. With spring coming in, I went to get the batteries to do some yard work and went to verify the charge on the 80V 4 A. There was no charge so I plugged it in. A red light started flashing. I retried a few times but got the same flashing light. I put in the other battery and it immediately got a solid green light. The battery remained fully charged. I consulted the operating manual and plugged in the 80V 4A, got a red flashing light, so removed it and waited a minute and retried. I still got a red flashing light. I then removed the battery and then the plug to the charger for one minute as indicated in the manual and then plugged it back in and inserted the battery. I received the same red flashing light. The manual notes that if this happens, the battery is defective. I was pretty upset with this since the battery was over $150 and it had been used no more than 10 times. I called Green Works warranty department and Nicole immediately picked up the phone, which is great given that customer service has gone out the window with Covid. Nicole said the battery could be replaced if I sent it in, but I wouldn't receive a replacement UNTIL AFTER THE END OF MAY SINCE Green Works HAS NO 80V 4 A BATTERIES. I was in disbelief. How is it that a company that sells only battery operated equipment has no batteries? I asked Nicole if there were any other options, and she said I could try with Amazon but otherwise they could do nothing. How am I supposed to mow my lawn for two months without a battery? (I could use the small battery but that would give me about 15 minutes or less of mowing time, not too practical). Nicole seemed not too concerned that I had spent $1000+ dollars on Green Works equipment that I have actually never even used yet other than the blower and that I wouldn't be able to use until sometime in June this summer because I wouldn't have a battery. I can't communicate to you the frustration I felt at that point. You would think a smaller company trying to make a reputation in the increasingly competitive battery operated outdoor/lawn equipment space would want to keep a new customer happy. But no, that didn't seem to be a priority. Fortunately, Amazon has a much better understanding of customer service than Green Works. They immediately answered my call, apologized that the equipment I had received was defective, and have shipped me a new battery that I will receive in a couple of days. Moreover, they will pay for the old battery to be returned unlike Green Works which was requiring that the customer shoulder this expense. I perhaps foolishly made the plunge into the Green Works ecosystem. I had hoped that they would be a company that stood by their products and would figure out a way to help a new customer like me actually use my equipment. I thought they would be a bit more apologetic too that their battery had only lasted 10 uses. That is after all rather pathetic. I really wanted to love this company, but unfortunately, I wouldn't recommend using this company until they get their house in order. It is one thing to sell defective products, but it is quite another to provide your customer no viable solution other than let someone else deal with the problem when they've sold you a defective product.

The Greenworks PRO 80V 4.0 Ah Lithium Ion Battery is a great upgrade if you’re using Greenworks 80V tools. Right out of the box it holds a strong charge, and I was able to get through multiple yard tasks without needing to recharge. It delivers solid, consistent power throughout the whole charge, even when using demanding tools like the blower and mower.

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.

Greenworks Pro quality. Not cheap but definitely a good quality. Use this in all my tools: mower, snow shovel, pole saw, chainsaw, blower. 80V is good power and 4ah makes it last longer. A bit heavier than the 2ah which was to be expected. Would buy again, but would love to see this fall on special at some point.

excellent battery .. gives a much longer use before it needs to be recharged than a 2.0 AH battery..much heavier than a 2.0 AH.. Only downside of this is using it in leaf blower

Bought this battery because the battery that came the snow thrower keeps running out of power clearing my double wide driveway. I have to recharge it at least up to 3 times to clear the driveway. So far this battery has cleared up to 3 inches of snow on a single charge. It ran out of power when the snow was 4 inches deep and I had about 5 minutes worth left to go.
