Greenworks 40V Battery. Original Greenworks 4Ah Powerful Lithium-Ion Battery for All Greenworks 40V Garden and Power Tools. Fast Charging, 3-Stage Level Control. 2 Year Warranty G40B4

Much better battery as I don't have to charge up so often, the smaller one I was charging all the time I can use this one and don't worry about getting it stuck in field while sorting horses as battery lasts a good 30 mins more....

This battery does not charge but the delivery man was nice

Charged well and holds charge for over hour with jet wash … good battery so far

This battery looks very similar to the first iteration of this item, and it is also rated at 1600W like its predecessor. It lasts as long as my other older 40v 40mAh batteries do in the same tasks. But its too big to allow my Greenworks lawnmower battery compartment cover to close over this new battery. This may allow excess dust into the battery compartment, with unknown consequences. This makes me reconsider whether its wise to buy any further Greenworks tools.

I bought multiple products and was looking forward to using them. however battery was complete disappointment . did not charge. the sellers refuse to return or replace . Now I have to return all machines some of it even unopened. what a shame. Have not had similar issues with other battery operated machine

Had problem with first battery, this very quickly resolved.

Habe den Akku als Ersatz für meinen alten Rasenmäher gekauft. Passt hervorragend und hält auch länger her als der alte Akku

Avevo una batteria in dotazione, ne ho comprata un altra e riesco a tagliare agevolmente tutto il prato con tagliaerba e decespugliatore. Consiglio

PARFAIT

- Comprada para la motosierra de altura "Greenworks G40PSFK2", ha sido un acierto pleno. - La máquina trae una batería "G40B2", de 2.0 Ah y 1000 W, que se queda algo justa pasa algunas maderas y grosores. - Con esta batería, de 4.0 Ah y 1600 W, me he atrevido a cortar ramas de "roble" de unos 10 cm. de grosor y, el tiempo de uso de la carga es notablemente superior a la de 2.0 Ah. - En mi opinión, "imprescindible" para algunos trabajos.

Il tempo di ricarica con batteria totalmente scarica è stato poco più di un ora, mentre il tempo di lavoro è stato di circa 50 minuti. confermo quindi quanto letto nelle caratteristiche descrittive in fase di acquisto. la consegna era prevista dopo 21 giorni, mentre è stata effettivamente consegnata dopo 26 giorni dalla data di acquisto considerando che lo stesso giorno avevo acquistato contemporaneamente il decespugliatore, la batteria ed il caricabatteria, la batteria è arrivata circa 3 settimane dopo l'effettiva consegna del decespugliatore e caricabatteria
