I have a gas saw and a battery powered one. While it is true that the battery saw doesn't last long, this is how it works for me. I'm an old (65+) man with fingers curling from arthritis. The battery saw can cut more tree down than I can haul away in the time it takes to recharge it. I think it has a 14 in bar, and I cut a Boxwood Maple (Acer negundo) thicker than that. It took me 2 days, but I found it works me less than the gas saw would have (and my ears didn't ring). For Harry Homeowner who doesn't cut firewood for a living, my Makita saw is becoming my new best friend.
