Great battery system.
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.

Buy the real thing!
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.

Handy for long days in the garden
A must have if you've multiple Greenworks batteries and need to constantly rotate them when working in the garden. Takes about 45 minutes or so to charge up the 40v battery. The main criticism I have is around battery cooldown. It often treats freshly drained batteries as too hot to charge, but the fan on the device doesn't cool the batteries down particularly fast, so it can take a little while for the charger to actually begin on hotter summer days. Overall though it's been a great addition to the Greenworks arsenal and helped greatly in getting my grass cut without needing to stop and wait for the standard charger.

Good battery.
Charges pretty quickly and holds it. Using it on a hedge cutter and lasts well cutting through some dense foliage. Also fits the Greenworks chainsaw and a few other tools.

Greenwood's 40v battery
Lives up to my expectations. Gives me 35 minutes of HD strumming with my Greenwood's strimmer/brushcutter. Well pleased.

Greenworks Cordless Rotavator
We used it to rotavate our chicken run. It works quite adequately considering the soil was quite compacted after a cold wet winter with the chickens on it. Battery life not v impressive but it did have to work quite hard. Instructions to put rotavator together were pretty clear.
