Greenworks Battery 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.

Very long lasting charge! As you'd expect. Quite heavy in use but the charge seems to last forever. I finish my hedge cutting long before the battery runs out. There's usually slightly less than half charge left after cutting my hedges that are 110' long by 6' 6" high and the other 60' long by 6' 6" high. Definitely along laster in use. Also it holds its charge well over several months, seemingly without losing any charge!I haven't run the battery anywhere near flat and have only needed to top up the charge which hasn't been a problem. I think it's expensive and heavyish in use, hence only 4 stars.

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.

The battery fits 2 of the power tools I have, so only the 1 battery was purchased

very good

I bought this along with the "Greenworks Tools 51cm (20'') 40V Lithium-Ion Cordless Battery Long Reach Hedge Trimmer"It does what it's designed to do, it powers the whole 40v GMax range of power tools.It's had plenty of use and seems very reliable so far, it keeps running at full power right up until it goes flat (no power fade).The runtime is approx 60 mins and the charge time is also 60 mins.

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.
