GreenWorks G-MAX 40V 4.0Ah Li-Ion Battery
about 1 month ago2021-03-11T01:24:46+00:00
Brought this as I have the 2Ah and the 6Ah battery. By far my favourite battery as the release button is easy to grab out of the pole saw, hedge Trimmer or leaf blower . 6Ah battery and 2Ah battery stick quite a lot and need a really good grip to get them out. But 4Ah battery button design make it way easier

Lasts a long time. Get the whole lawn mowed on one charge. I can load it in to the blower vac and clean the driveway.
Not much to say really

Exactly what you would expect. Extra batteries mean you can do the job without waiting for them to recharge. The upfront cost of batteries is the biggest downside to battery power but it is what it is.
GreenWorks Lawnmower Battery

Got as an extra to use when the lawns are out of control and more power is needed to finish the job. Works a treat.

Awesome I can mow 800 square meters, on one battery charge
second mower battery
3 months ago2021-01-13T19:37:30+00:00
Purchased this as the mower came with only one battery and if in the middle of doing the lawns it's annoying to wait for a recharge so purchased a second battery and now I can finish all the lawns in one go, holds charge well and has a handy charge level indicator. Very happy with this product

Excellent battery for having as a spare.

Good to have with a larger lawn.
If you need extral power

I got this so I wouldn't run short when mowing the 1/4 acre. All good, it's good having a spare as then I can get straight into the weed whacking when finished the mowing.

Perfect for my needs

Easy to use, and fast to recharge. Powers my mower perfectly on my small to medium section.
4 months ago2020-12-09T04:32:59+00:00
With only one battery and a very large lawn, one battery was not quite enough if the grass got a bit long. A 2nd battery and problem solved. Lawn mowed in one go !
Back up Battery Saves the Day
5 months ago2020-11-21T01:32:40+00:00
One battery is enough to get the yard done if you keep the grass short. We had long lawn on our hands when we first started, though, and we found out very quickly that we'd need a back up battery if we wanted to wrangle that and whack weeds on the same day.

Very happy with this product
Gives endurance to tools

Gives 30 minutes + usage to line trimmer and hedge trimmer tools.
7 months ago2020-09-11T18:22:41+00:00
Great to have a spare as it doesn’t last more than about 30/40mins when mowing the lawns and I need a good hour for that.

I purchased another battery to go with all my existing Greenworks equipment, so I had 2. Makes life easier if I forget to charge one. It works great! No problems!
G-MAX 40v battery.

I brought this battery as a backup for my lawnmower. The 1st battery ran for 40min. in which it mowed nearly the whole section (525sq metre) which was partly wet and dense in places. I then plugged in the 2nd battery to finish off, which took 10min.The battery only used 1 bar.
about 1 year ago2020-04-05T20:37:01+00:00
Plenty of battery life to complete jobs without worrying about a flat battery part way through.
about 1 year ago2020-03-03T21:35:00+00:00
Holds its charge well and gives 40 minutes of continuous mowing. I have two of these batteries for my Greenworks lawnmower, which has been the best investment I've ever made.
about 1 year ago2020-01-07T20:06:06+00:00
I bought this as a back up battery for my Mower. Works well, lasts longer than the Victa battery, and is quite a bit cheaper. You just have to cut a couple of tags off so it fits in my Mower's connector.
great power from this battery

I have purchased a second battery fro my GreenWorks lawnmower as my lawn is large and i was not able to get it all done on one battery but Im impressed with the length of time and power i get out of this 4Ah battery.
about 1 year ago2019-12-10T19:20:21+00:00
The 4.0AH battery has a longer endurance than I expected. Plenty of power and time.
about 1 year ago2019-11-24T07:11:52+00:00
I needed this extra battery for my Greenworks lawnmower. it lasts up to 40 minutes depending on how thick the grass is. It's great to have a spare battery as a back up.
A bit more time

Brilliant add on to the mower having two batteries now as we live on a large 3000m2 section. Even have left the ride on in the shed a few times now
about 1 year ago2019-09-07T18:18:34+00:00
Wow! So happy with this battery so I brought another 2. I have several GreenWorks products that I use and these batteries last and have heaps of power - Awesome!!!

Excellent Power and Charge

Great combination products – do all they’re expected to, and certainly deliver extended output and solid power. Recharge is a breeze. And as someone else has mentioned; while the battery is heavy, this ensures it provides a good balance to the tools.

The battery delivers plenty of power to the chainsaw. I held off buying a second battery until I tested the first. i will buy a second one now

Truly happy with the power I received and this 4.0ah size just lasts a long time.
over 2 years ago2018-10-14T08:42:03+00:00
What a brilliant product and keeps its charge lobger than I would have thought. Have purchased the GreenWorks Chainsaw, Pole saw, Trimmer and Blower previously and they are fantastic. Going to the battery tools is certainly easier and easier especially for the smaller jobs although I have used all of them quite hard too.
Essential battery for greenworks tools

Good design, has handy status gauge for seeing how full it is. Good to have a spare so you're not waiting for first one to charge.
over 2 years ago2018-10-04T05:53:57+00:00
Big 4 amp hour battery enables my chainsaw and line trimmer to work for longer than I have the strength to use them! Recommended.
