A New Chainsaw, with a Hidden Cost

Santa Claus dropped off a new Husqvarna 120i battery-powered saw this year.

Santa Claus dropped off a new Husqvarna 120i battery-powered chain saw this year.
 
In back, that is a mid-1980s 49 cc “Rancher” saw, originally Dad’s firewood saw, but mine for some years now. It still works well. It has a 15-inch (38 cm) bar and weighs (without fuel) 13.2 lbs. (6 kg).

The battery-powered saw has a 14-inch (35 cm) bar and weighs 11 lbs. (5 kg). It is, however, longer overall because of the space needed for the battery. And lithium batteries require mining lithium by cutting down rain forests in the Philippines or wherever. Just search on "environmental cost of lithium mining" before you feel virtuous about foregoing gasoline.
 
It is supposed to run for 45 minutes or so before dying — I have not yet tested that part.
 
I cut up some small oak and pine for a test, no problem at all.
 
So this will be the saw for quick jobs, especially those close to the house, and it gives me a backup in case the gas-powered saw has a problem. And it is quiter, probably because the old saw's muffler is kind of rusted out.

Good Husqvarna quality — but not necessarily any more environmentally virtuous than burning gasoline. Californians, however, won't have any choice after 2024.  (I bet all the wildland firefighting sawyers wil hang onto their gas-powered saws as long as they can. Forty-five minutes is not very long on the fireline.)
