Your comments here about how problematic battery powered electric outdoor power equipment can be are dead right. It will be a sad day when the ICE is gone, but like it or not folks the ICE's days are numbered. For so many reasons, but mainly b/c emissions controls and safety regs have made ICE machines consumers hate. I say its mostly b/c of fuel and quality of build issues that make starting difficult to impossible (For example my camping generator) when left for a few weeks.
As a consumer whose been using ICE equipment for 50 years, I'd say that anything with an ICE made in the last 10 years will break down, and be way more expensive to repair, if it can be repaired at all, than it would have been 20 years ago. Everyone I know shops at Lowz, Home Despot, Walferts, et all. They buy cheap junk because they think they can't afford better, or "why spend more when it's just going to break anyway". Even "expensive" zero turns fall into this. They then tire of repairs, especially rebuilding an ICE carb or fuel system after it's been sitting for 3 months. They hate dealing with fuel preservatives like Stabil and especially forgetting to use it when it won't start.
Even I love how quiet and easy to use my electric corded chain saw is, and its 15 years old. And sure in a few years (if we are lucky) these newfangled batteries will have to be replaced.... but more likely in 5 years there will be a new, smaller, lighter and faster, cooler (sales pitch) replacement. So yeah, we are a disposable society, but people throw throw their $800 phones away every 3-5 years, so why not their electric lawn mower?
As for me, I will be using my newish Craftsman walk behind and 20 year old all steel MTD Yardman Yardbug Rider for as long as I can get parts. Maybe my relatives will have to pull me and my dying hands off of the Yardbug, but more likely they will pull my dead body out of my SeaHunt boat with its 2006 2 Stroke Yamaha engine that sends up a cloud of smoke every morning I go out fishing.
If you are in the business, you all better find a way to sell or be using all this electrical stuff, or get out of the business.. because that's all there's going to be in 10 years. Nobody's going to be fixing anything but the most expensive equipment anymore. Think IPhone. Ugh.
