When is an 18v battery a 20v battery?
In the 18v circular-saw review in the April/May issue of FHB, I noticed several photos of saws that had 20v batteries. How can it be a review of 18v tools when some saws had 20v batteries?

Associate editor Patrick McCombe replies: It’s marketing hype; those batteries are all 18v. They produce 20v when they’re fully charged, but this voltage drops off almost immediately in use.
