    New model.
    Got this on Prime day for under $100 which is a great price. It is labeled as manufactured in November 2020 so it's fresh. I charged it up as soon as I got it with no problems. It is a new model and I don't know what has changed internally. The colors have changed a bit and the check battery button has changed position. It fits most of my devices but I was surprised to find the height has changed a small amount but enough to prevent the cover on my lawn mower from closing properly. This is the dual battery mower. It may fit other models. If you have no cover it will fit fine but just be aware of this minor issue. It works in my mower just the cover does not close completely

    One charge edged my grass(have a fence-effectively edging inside and outside the fence), used to trim my bushes, then the same battery to blow the drive, sidewalks, and front door. The battery was only down almost halfway. This battery held its charge over two weeks off the charger. I will buy again.

    This battery works great with the mower and chain saw, but will not work with the tiller model 27062A s/n GWV1720282 06/20/16. The new battery is too large and will not permit the green door to close. If the door won't close then the magnetic interlock prevents the tiller from running. I also have a new 40V 2.0A battery that causes the same issue. Please advise a solution.

    I bought an aftermarket type that said 6Ah and had good reviews.
    Beware of those as mine only ran the mower 5 minutes!
    I learned my lesson, now I will only buy Greenworks batteries.
    This one worked as expected for the time expected before needing recharging.

    My GreenWorks mower and edger came with 1 battery. I needed an extra battery, so a little over a year ago, I bought a generic battery for a lot cheaper than the GreenWorks battery. Now I now why it was cheaper. It stopped working barely over a year later. So, I bought a new GreenWorks battery and it works like a charm.

    This battery does not fit in the 5 AH charger or the lawnmower. Not returnable because it's a 'chemical'. Okay for the seller to ship, but not the purchaser. Very dissatisfied.
