I have been considering a battery powered hedge trimmer. The boss of the house has several box hedges in front of the house, that are only a foot or so high. She insists, that, they be trimmed round. No matter how careful I am, the cord on the trimmer
WILL eventually fall into the blade and get cut. I have spliced and re-work, so many cords that I probably could have paid for a battery powered trimmer.
@DesertRatTom I will agree to disagree with you on the Ryobi's. I find that they are more than adequate and reliable in a home shop/handyman environment. I would never use them in a professional capacity, but like them better then the DeWalt tools. Don't get me wrong, I like the DeWalts. I own a bunch of them. However, they are all packed away because I got tired of the overpriced, expensive batteries heading South every time you glanced at them sideways. I don't have that problem with my Ryobi LiIon batteries. Additionally, the Ryobi batteries seem to have longer run times, are more robust and less prone to damage and, at least subjectively, seem to be better balanced when in the tool(s). However, (hopefully) DeWalt has improved these shortcomings in the past decade. To each his own. I would love to pull my DeWalts back out of storage if only they would improve their power supply system.
As for the battery powered router. Why? I agree with Cherryville, unless you are a professional and don't always have access to an outlet, stick with a corded tool. The additional bulk is just not worth it. The cords on my routers never seem to be in my way. If they were, then there is probably something wrong with my set-up and I didn't think it through.
Gerard seems to have summed up the thoughts on the cordless router best. Unless you just have to have a unique tool, or have a specific need, I would pass on the router.
