Our take on the DEWALT 12V MAX Oil-Resistant 5.0Ah Battery with Fuel Gauge - DCB126G

The DeWalt DCB126G is a 12V MAX lithium-ion battery pack rated at 5.0Ah, the largest capacity in DeWalt's 12V MAX line. Its glass-filled nylon housing is made to resist oil, grease and solvents, and a built-in LED fuel gauge shows charge level at a glance. It fits DeWalt 12V MAX tools and chargers that accept the 12V MAX slide pack. Against the standard 2.0Ah and 3.0Ah packs, it trades extra weight and bulk for longer runtime, so it suits users who run 12V tools hard rather than those counting grams.
