Yeah, your miter saw will run on a 2ah battery, but it’s going to put the battery through heck to do so. ![]() This is a big part of the reason certain tools should use batteries with a high amp-hour rating. Each cell in a battery has a limited amount of power that can be drawn from it at a time. What about the power claim? That takes some clarification. Is it all smoke and mirrors though? Can the PowerStack really do everything it claims? And how can a battery that’s rated at 20v and 1.7ah have 50% more power? Off the bat I can tell you that the PowerStack is lighter and smaller than a normal DeWalt battery, no doubt. As you can see below, there’s no wasted space between the cells. ![]() DeWalt is using flat cells – almost like a cell phone battery – instead. The more cells a battery has, the higher the amp-hours. Most batteries feature cylindrical power cells almost like a bunch of AA batteries arranged in the pack. How does all of that happen though? It’s all in the shape of the power cells inside the battery. The stats on the new DeWalt PowerTech 20v battery are impressive on paper 25% more compact, 15% lighter weight, 50% more power, and double the expected battery lifetime of their standard 2ah 20v battery. ![]() Modern batteries are more efficient, more intelligent, and more reliable than ever before… but the new PowerStack might render them all obsolete. I know it won’t be another 13 years before we run that sort of comparison again and the big reason is battery tech. This is the first time we’ve done a drill comparison since 2009, and not to spoil anything, but the drills of today absolutely run circles around the ones of yesteryear, and it’s not even close. The staff here at Popular Woodworking just wrapped up a 12v drill competition that will appear in the August issue of the magazine.
