Great batteries. Purchased the 40v 4ah to replace the one that died this winter. That battery was purchased 9 years ago. The 40v 2ah I purchased at the same time is still working. If I even get half of that use from this new one I'd still be satisfied. All of the tools I bought at that times also still work flawlessly. Mower, edger, leaf blower, hedge trimmer and pole saw. 3 year warranty on their batteries is good.

I got this as an extra for my Greenworks leaf blower. The one that came with it has worked well but may be losing just a little capacity after 2 years of pretty regular use. Nice to have two for Fall cleanup.

Battery works well, takes a charge and operates the lawnmower. I hope it lasts! I ordered the 4 Ahr battery instead of a 5 Ahr battery, because it has a better record for lasting longer!

Buy the right battery for the right Greenworks product. NOT all 40 V batteries and Chargers work on all 40 V products. There are differences. Check with Greenworks and check Carefully. Be careful of off brands, with Greenworks tools. I have tried a couple thinking price was worth the risk... it was not. Both times the Batteries failed. Fortunately, I was able to return them for full credit but wasted a lot of time. At the time Greenworks was out of stock on the battery I needed and wanted, and I did not want to downsize to a lower capacity battery for a backup. Check online and make sure your product is listed for that battery before ordering and make sure they accept returns if it does not work on that product as advertised.

I have numerous Greenworks' implements: chain saws, pole saws, leaf blower, and weed whacker. The weed whacker (string trimmer) is the one implement that I typically use continuously for multiple hours. I have two 2ah Greenworks' batteries that last about 15 minutes from full charge to depletion. My one 4ah battery typically will run for about 40 minutes on a full charge. I wanted a second 4ah battery and after doing some research I decided on an authentic Greenworks' battery and not a "knock-off." My new 4ah battery has a similar run time of about 40 minutes. By alternating their use, the batteries will last longer than my body does. When I'm done I give both batteries a full charge and put them back on the shelf. Sometimes months will go by before my next use but the batteries have maintained a full charge. Very convenient, long lasting and worth the additional cost. Note: I use the 2ah batteries in the chain saws and leaf blower where they last plenty long enough for the given projects.

Je ne peux pas utilisé la batterie elle n’est même pas pareil à celle sur votre photo!!pas compatible avec les accessoires même si elle était suggérée !! Peut-être défectueuse ou incompatible mais Je ne peux pas la retourner avec la polique de retour donc j’ai déboursé presque 300$ avec les frais de livraison et douane pour absolument rien!!
