    It does what it’s supposed to do with a bit of a struggle getting the battery in and out.

    An additional battery for my growing collection of Greenworks Garden Tools. Battery life when fully charged excellent, occasionally a little difficult to eject from charging unit.

    Just had a spare battery delivered. It charges quickly and fits the charger and equipment I already had. Thought it was a tad expensive though! What more can be said?

    La batteria pienamente efficace. Resta uno strano problema quando, scarica, la metto nel carica batteria. Succede che non la legge. La spia luminosa che segnala la messa in carica….rimane fissa. Nulla di grave. Ma…con un distanziale da ca.1 mm. ( cartone o plastica rigida ) fra le lamelle della batteria, si risolve il problema. Probabile che entrino in gioco gli incastri del tagliaerba e gli incastri del carica batteria. Occorre ingegnarsi. Saluto tutti.

    Bought the strimmer, hedge trimmer and 3 batteries for my gardening business last month and am delighted with them all. Got a very good deal on the hedge trimmer and one battery in a flash sale on Amazon Primer Day. The strimmer is quite powerful and cuts down over grown weeds and grass easily. As has been said in other reviews, the 2a batteries last about 20 mins which is good enough if only strimming a garden border. Very light and have had no issues with aching arms, shoulders, fingers or vibration in hands which I had with the petrol strimmer. (I’m 64) The batteries charge in an hour which is just enough time for me to get one charged up at lunch ready for the afternoon jobs. When using, just make sure you only use enough power required to strim the grass and not use full power unless necessary and you’ll get maximum time from it. Hedge trimmer seems no different from my Ryobi 18v trimmer I must admit.

    Easy to slot into the housing on the lawn mower.
    Got a second battery as one fully powered one just doesn’t make it to the end of lawn.

    The battery provided with Greenworks lawnmower is poor – lasted only 20 minutes, so needed an extra one. Such a better price on Amazon compared to directly buying from Greenworks & lasts longer than the original.

    Good product but costly. Especially combined with charger. Main product cannot work without battery and charger. Package should Be clearly advertised as necessary for trimmer/ chainsaw to work as it is not included.

    I use this product to power the Greenworks Garden Cart, which I use for poo picking in my horses field. Great power range on gradients with full load. Not been left without power yet. Been using it for approx 4 weeks.

    Although slightly different in appearance/finish, the battery does the job for which it was intended. Thanks folks.

    Good product nice that it shows you how much charge is on the battery just wish they where a bit cheaper as I could with a 2nd one

    Although these batteries have a good run time it’s a good policy to have a spare that’s fully charged and ready to go when the battery in use runs down. The battery I replaced was three years old, so presumably that’s there life span.

    Best battery for your greenworks tools. I do own five. Some tools do drain the battery faster than others, so a chain saw is best used with a 4ah battery than a 2ah.

    Golden Review Award: 2 From Our UsersHo comprato questa batteria a supporto di quella in dotazione della mia motosega. Mi sono accorto quando arrivato il pacco, che questa batteria grande il doppio di quella che avevo, duplicando il tempo di taglio con la motosega.
    Ottimo prodotto, si carica anche molto velocemente.

    Golden Review Award: 8 From Our UsersIch habe den Akku als Zweitakku fr meinen Duramaxx Mher von Obi gekauft (DD40LM46SP). Im direkten Vergleich zum Obi-Akku wirk dieser etwas hochwertiger in der Optik, allerdings ist das ja eher nebenschlich. Meines Wissens ist Duramaxx ein Lizenzprodukt von Greenworks, prinzipiell sollten die Modelle untereinander also kompatibel sein.
    Von der Leistung bin ich bis jetzt sehr zufrieden: knapp 400m2 MIT Radantrieb ist fr einen 4Ah-Akku meiner Meinung nach echt in Ordnung, jetzt muss sich die Langzeitqualitt (Ladeverhslten, Leistungsabgabe, Anzahl der Ladezyklen…) zeigen.
    Mit dem normalen Duramaxx-Ladegert bentigt der Akku ca. 3-4h, bis er vollstndig wieder aufgeladen ist, dass sollte man bedenken, bevor man grere Rasenflchen am Stck mhen mchte.

    Fazit: funktioniert mit dem Duramaxx-Mher ohne Probleme, leistungsmssig ist der Akku klasse. Mit knapp 140 Euro ist das Teil natrlich relativ teuer (wie es Akkus in dieser Leistungsklasse eben sind), Qualitt, Verarbeitung und Leistung berzeugen aber.

    Ich hoffe, diese Rezension ist fr Ihre Kaufentscheidung hilfreich
