In this video I put five BIG battery chainsaws—20 to 24 inch bars—through a real head-to-head to answer the question a lot of you have been asking: is there a true battery replacement for a 20-inch gas workhorse? We tested DeWalt 60V, EGO 56V, Greenworks Commercial 82V HOG (24”), Milwaukee M18 FUEL dual-battery, and Ryobi 40V HP. My goal here was to stress these platforms the way tree care, forestry, and serious property owners actually use them, not just make a couple of easy cuts and call it a day. We scored each saw across weight, noise, speed cutting, crosscut runtime, and a brutal milling “torture test,” plus features and ergonomics (price wasn’t included in the final score, but we did use it for best value). Greenworks HOG flat-out dominated speed cutting and crosscut runtime and earned the overall win—this is the closest thing here to a true gas saw replacement, but it’s also the heaviest, loudest, and most expensive. Ryobi shocked us with how competitive it was while being the lightest and took best value. Milwaukee wasn’t the fastest, but it showed serious endurance and efficiency in long, demanding cuts—especially milling—while EGO and DeWalt were solid if you’re already in their battery ecosystems, but they bogged down when pushed hard.
