Cordless tool batteries do not cross brands: a DeWalt 20V MAX pack fits DeWalt 20V MAX tools, a Milwaukee M18 pack fits M18 tools, and so on. Capacity is printed in amp-hours (Ah), and the price per amp-hour is the comparable figure: a two-pack of 5.0 Ah batteries is 10 Ah, and each brand’s page here works it out at today’s price. A starter kit adds a charger, so its price per amp-hour runs higher than a bare pack’s. DeWalt 20V MAX, Milwaukee M18, Makita 18V LXT, Ryobi 18V ONE+ and Craftsman V20 are all 18-volt batteries under the badge, so their amp-hours compare directly; EGO’s 56-volt and Greenworks’ 40-volt packs run garden tools and hold more energy per amp-hour. Each card names the seller, and a Milwaukee or Ryobi pack on Amazon is often a reseller’s rather than the brand’s.
