They throw them out once something does go wrong, that's why! they are basically a bloated cordless drill on wheels!
I'd be really interested how the cordless LI ON battery powered chainsaws do. I think for backyard use, they would be fine, only thing is infrequent use is not good for the batteries. That's where an electric chainsaw is probably best.
