The technology is here, just not marketable at a reasonable cost. Super capacitors, graphene technology all exist now. It's just too expensive for the masses at the moment. Just as lipo batteries replaced nimh and nicd batteries these newer technologies will replace the old. Just a matter of time. I'll always keep my old 2 strokes going as long ad I can get parts, but also see the feasibility of one day owning smaller battery powered equipment as well. And truth be told, stuff ain't made like it once was. By the time both batteries are shot in your cordless drill, the drill is about spanked as well. I only made the mistake of getting a new battery once, and shortly after the drill conked out. I dont forsee people getting motors and speed controllers replaced in electric equipment, batteries wont get rebuilt, and it wont be worth the cost of replacement to buy a new battery.
I also largely believe a lot of shops have done this to themselves. They dont want to fix saws, or other o,pe. Heck some of them dont even want to do warranty work. I've fixed plenty of equipment for the locals that live near me all with the same story. Took it to the dealer, they said just best to buy a new one. Let me go get the salesman. At work weve sent equipment to dealers to repair (for lack of time for me to do it) to get it back "fixed" and doesnt run any better than before the dealer touched it. It's a sad state of affairs however you choose to look at it.
