I avoid battery-powered tools. They are wimpy, and the batteries will die in a
year or two.

You have a cellphone?

Sure, a simple one. I charge it about every other week, and I've
replaced the battery once. But it's not a power tool.

You're not going to get a horsepower or so out of a battery for long,
especially when the battery is two years old.

You're not going to get a "horsepower or so" out of a hand tool.
You're in the stationary tool realm at a HP (Craftsman HPs don't
count).

120 volts, 15 amps is 1800 watts. Lots of circular saws pull 13 amps,
1560 watts.

Cordless circular saws (even small 6.5" ones) are close to useless.

Not so. I have a DeWalt that's quite nice on plywood and such. I
also have an older Makita that's great for cedar siding. It sure as
hell beats a 10lb. corded monster when you're trying to trim a piece
of siding, 15' up a ladder on the side of the house. ;-)

I've got a Hitachi one that came in a kit- cut up few ~2" branches
that were felled by an ice storm and it was already dying.

A circular saw used on a tree? You must be suicidal. Cutting a 2"
diameter branch with a 6" saw? You *have* to be! Haven't you ever
heard of a chain saw, or even a reciprocating saw? ;-)

Aren't trees still made out of wood?

Yes, and fingers are still made of skin and bone; much softer than
even wood. Circular saws are very dangerous things when used by a
someone with no respect for them. They are *not* designed for this
sort of thing.

and a chainsaw is safer?
