Is there a core charge on them like automotive lead-acid batteries? That could solve most of the problem.
I don't think buying a new battery six years is too bad. If I planned ahead I could have gotten free shipping and the battery cost $99. So about $16 per year and the electricity is virtually free. Probably not cheaper than a cheap gas mower if you do the maintenance yourself, but pretty economical with the bonus of zero emissions, zero maintenance and quiet and clean. No core charge on the Neuton lead-acid batteries. I still have the old one and have to figure out how to recycle it.
If they really are LiFePO4 then there is nothing really toxic in them.. mostly copper, aluminum and plastic. $88 on Ebay.. thats an incredible deal for my 1/4 scale Piper Cub http://www.ebay.com/itm/GREENWORKS-...019?pt=LH_DefaultDomain_0&hash=item2ebf676d23
Hmmmm...... Now I have no excuse not to go electric. I don't like the idea of fighting a cord and I don't have electricity ion my garage , but it looks like battery electric mowers have gotten serious. I will do some shopping.
A little under 3 pounds and it looks to be fairly compact, as well. They don't list length/width/height but the Torx screw heads give an approximate scale.
My Neuton is the smaller (14" deck) and has a 24V 10Ahr battery. It runs for about 1 hr so the electric motor is ~240W or about 1/3 HP. The one with the bigger deck and 36V battery is probably more like 1/2 HP I would guess. I would say that the 1/3 HP is about right for the 14" deck, as I have never had trouble cutting tall grass with it unless the battery was really low SOC. Greenworks battery seems wimpy. 40V 4 Ahr is only 160 Whr, whereas my battery has 240 Whr. Assuming the Greenworks motor is similar power, you will likely only get 30-40 minutes out of it. Also the Greenworks is driving a 19" deck so I am guessing that the motor is more powerful thus impacting run time even more. You should plan on purchasing a second set of batteries, 4 total if you need to mow for ~1hr. Since the Neutons are sold out for the year, I would suggest you look at this one: http://www.amazon.com/Black-Decker-...15&sr=1-3&keywords=neuton+electric+lawn+mower
The greenworks 19" lawnmower manual: http://www.powerequipmentdirect.com/manuals/25292OM.pdf looks good but does not say what chemistry they use.. still I think its LiFePO4 due to lower cost an made in China.. keep it charged to 100% all the time and top it off every month.
