I bought this about the middle of last year (2008). The battery lasts very well - I've got a small lawn at the front and a fair sized one at the back and I can do both of these on one charge, with little apparent depletion of the battery. (battery charge is indicated by several lights, 3 greens for the level of charge and red for depleted, and even after use, I've never seen it yet without the full number of lights on. It picks up really well too, leaves, odd twigs, etc are all taken up and put into the reasonably sized grass collector. When I've finished mowing I just plug it in in the shed, and leave it for a couple of hours. Job done, and a lot quicker than it used to be! I wouldn't go back to a corded or petrol one now, and if this one dies on me, I'll get another one of the same make!.
