Fast chargers are a feature on many of the cordless chainsaws. I thought about getting a spare battery for mine when I first bought it, but I don't need one. One charge lasts longer than I care to work without taking an iced tea break,..and it takes about 40 minutes to put a full charge in the battery
In other words, the battery doesn't hold me back at all. It cuts a *lot* on a full charge and I've never really ran the battery down to nothing. I might deplete it about 60% before I'm ready for a break if I'm feeling particularly motivated. By the time I'm ready to get back at it the battery has another full charge in it.
