A couple months ago I picked up a Husqvarna Power Axe 350i Cordless Electric Chainsaw. It is a lightweight 18 inch chainsaw at Lowes for $349. I'll never go back to a gas saw. A full charge on the battery will power the saw about as long as a full tank of gas with a similar size ICE chainsaw. It saws with a slower rpm, but has a lot of torque. If you let the saw do the work you can easily cut through large oak rounds. I cut up a 14" diameter oak tree with no problems. A big benefit is you don't need any ear protection the saw is so quiet. Also, the saw only runs when you pull the trigger, so complete silence in between cuts. The battery takes about three hours to re-charge, so if you are going to cut for extended periods it won't work for you. At age 72 I find that one battery charge is enough cutting for me. If I still want to do some logging I'll drag the wood home and split and stack it.
