GreenworksBattery G40B2 (Li-Ion 40 V 2 Ah Rechargeable Powerful Battery Suitable for All Devices of the 40 V Greenworks Tools Series)

I have previously written positive reviews on the Hedge cutter and Chainsaw which this battery powers. In both cases I have been very impressed; although the products may seem expensive once you factor in the cost of the battery, charger and appliance, they are very convenient and work extremely well. I have expressed some caution at their aftersales service in the unlikely event that a fault develops (as it did with my hedge cutter) but this was eventually resolved to my satisfaction and I remain supportive of this range.The battery is both unexciting and fundamental. Available in both 2Amp/H and 4Amp/H (which runs for roughly twice as long on one charge of course) they are expensive at first glance. Particularly when you then need a dedicated charger which is going to add a further £25 or so to the bill. But again, they do work well. They balance the weight of the tools nicely in use. And when I think that I'll not have to buy petrol and 2 stroke oil for my chainsaw and trimmer in the future, then maybe - just maybe - they'll eventually save me a large proportion of the initially seemingly high price. A bit easier to justify if you bear that in mind?

Really wish they were cheaper but great battery. Charges quickly and lasts just long enough to get the job done. I’ve used this in my chainsaw which is brill. Gave me well over 100 cuts and also in my mower which has enough juice in it to do my entire lawn. Easily 100 sq metres. I may measure it and put the actual size up later just so you guys know exactly what it’s capable of. It’s such a pleasure not dragging cables around with me when I’m working in the garden now. That alone is worth the venture into battery operated tools. Good stuff indeed.

I have this in conjunction with the 30cm chainsaw. Very easy to install in both the chainsaw and the recharging unit, and recharge is fast. Battery is a little underpowered to run the chainsaw as I only get about 30-40 logs from a single charge (and these were seasoned softwood, so easy to cut). The 4Ah battery would definitely have been a better buy. That said, a good product thus far.

I have Greenworks; lawnmower, scythe, strimmer, hedgecutter and blower. I have four, 40V rechargeable batteries, each can be fully charged in under two hours. These tools make gardening fun, useable by both males and females. I am surprised at the scope of these tools and highly recommend them. I have no complaints but recommend you buy at least two batteries.

very good

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 purchased this product and separate charger for the 30cm Greenworks Battery Chainsaw. It is a straight forward process to lock the battery into the charger. The battery charged the first time in just under three hours. It is a little fiddly to get it into the chainsaw housing but once done you'll know how to do it again. I cut branches and trunks of various diameters of up to 10 inches for two hours and saw that the power delivered to the chainsaw was as strong when I finished as when I started.This battery will also fit other Greenworks tools such as the lawnmower and hedge trimmer.

The Battery was on charge for all day and night. It Just goes Flat after using it for about ten Mins.Asked to return the Battery or Replace it So far only post it back to them.We are unable to leave house as we are high risk.Asked the company for advice and they so just return, We bought three different Gardening Equipment with the same make.It looks like we have to return all.Unless the company gets back to me and advice if we are charging the battery correctly.

Double l'autonomie de mon souffleur. Forcément plus lourds qu'une batterie moins puissante mais bien plus pratique !

E' un'ottima batteria, dura per circa mezz'ora ma si carica velocemente.C'è stato un ritardo nella consegna, non per colpa dalla ditta Greenworks Tools, bensì dalla dogana.Greenworks Tools si è comportata in modo professionale, rispondendo puntualmente alle mie domande e scusandosi per il ritardo, mi ha omaggiato un coupon che ho utilizzato per l'acquisto di un carica batteria.

Works great, no problem at all.Huge capacity and not heavy.

super mais dommage le prix assez cher !

La batteria è 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.
