Greenworks40V Battery. Original Greenworks 2Ah Powerful Lithium-Ion Battey for All Greenworks 40V Garden and Power Tools. Fast Charging, 3-Stage Charge Level Control. 2 Year Warranty G40B2

A well made battery that is consistent in output. I would however have liked to be able to purchase the 4Ahr. model since using it with my strimmer blade it only lasts for a few minutes.These are seemingly a little scarce at the moment, it means that for me to get 4Ahrs. I have to purchase two batteries so the cost jumps up considerably.Still with that said, the heat build up in them is less, and I suppose that will lead to a longer life span for the 2Ahrs. type.I did have a so called 5Ahr. copy of the battery that performed perfectly for three or four discharge and recharge cycles, then it died, shorted cell or cells internally, can I get a replacement no chance. In conclusion do not buy copies, they are rubbish and you have no actual warranty with them since to send the back to the supplier is at your cost and they then tell you that you have abused the battery.Stick to the real thing, you can be sure that the warranty is real, in the unlikely chance that you need it.

I purchased 2 of these batteries while they were on a special discounted price and a Greenworks G40UC4 40V Fast Charger. The reason I bought 2 batteries was to allow me to charge a battery while using the other. The batteries recharge fully using the fast charger in under 30 minutes while a larger 4ah would take 60 minutes but last longer and was more than twice the price. You do need to bare in mind that once the battery has been used it will not charge straight away as the charger recognises high temperature. The battery can be placed on the charger and the built in fan cools the battery in 15 mins before recharge starts.My only slight complaint is the time it takes the batteries to run out of charge. I also purchased the GD40LM46SP 40V Lawn Mower 46cm Self-Propelled on a special price from Amazon and the battery lasts 15 minutes if I cut and use the self drive. The mower by the way is brilliant (see my other review). I have a large sloping uneven garden so really I should have bought 3 batteries or a larger AH rated battery but that was costly. All in all a great system that I would highly recommend.

Purchased to stop the inevitable from happening- an expensive addition to an expensive hedge trimmer but ensures the inevitable battery running out is minimised.Unsure why on earth a second battery isn’t offered at a discounted price when purchasing a tool at this price point but I’ve come to learn that there a lot of things in life that I don’t understand.The test battery level button is handy to check the charge level.First I impression is that the battery is quite bulky (maybe the 40v need the space).

was hesitant about this but it is excellent

Earlier this year I bought the cordless leaf blower and 2 battery package on Amazon from the Green works page. Used the blower, loved it. After charging the batteries for the 2nd time, one of the batteries failed to work so I contacted Greenworks through amazon stating what the issue was along with the serial number of the non-serviceable battery. They sent me a reply saying they couldn't find the purchase or the item, despite buying it direct from them. I sent them an email direct through their website, with the Amazon purchase reference and the battery serial number again, no response and still no replacement battery (battery failed within 3 days of purchase).After so many months struggling with one battery I have purchased another battery at my expense because a replacement has not been sent.While I love the blower and would personally recommend it, if you don't mind shelling out more cash to replace a faulty item then buy one. If you want a replacement of anything faulty through customer service under consumer rights don't bother because it seems like they really don't care.

Good value for money. We now have two battery's, which means we do not get frustrated when the first one runs down. They last for a good time. Nice and chunky. Very positive fit into the machine. I think a very good product, at a reasonable price.

I already have two of these batteries, so no surprise that this one is as good. No complaints.

Reasonably good price. I use 2ah battery with my Greenworks cordless pressure washer which lasts for 8 minutes. However, the water flow lasts for 4 minutes when used non-stop. I have 6 of these batteries and this lasts for 48 minutes which is more than enough to clean 2 cars at once. The battery does get intensively hot after use, so best to put it in a cool place as it won't charge unless the heat reduces.
