Model number 48-11-1855, this 5.0 amp-hour pack slots straight into any M18 tool or charger you already own.\u003c\/p\u003e\n\u003cp\u003eIt delivers 50% more power than the standard REDLITHIUM XC5.0, landing at PWR Level 3 on Milwaukee's REDLITHIUM Power scale. That translates to less bogging down on hammer drills, impact wrenches, and saws that pull hard current. The fuel gauge button has been reworked too — bigger feel, easier press, faster read — so checking charge state on the jobsite doesn't mean squinting or guessing.\u003c\/p\u003e\n\u003cp\u003eBuild quality got the same attention as output. The pack construction routes water away from the internal electronics and out of the housing, cuts down on heat buildup that shortens battery life, and is built to shrug off drops and vibration instead of failing from them. REDLINK Intelligence runs the show behind the scenes, keeping constant communication between tool, battery, and charger so the pack protects itself from overload without you thinking about it.\u003c\/p\u003e\n\u003cp\u003eBecause it's part of the M18 platform, this battery is fully compatible with 300+ M18 solutions — meaning it's not locked to one tool. Buy it once, run it across your whole M18 lineup.\u003c\/p\u003e\n\u003cp\u003eThis is the pack to reach for if you're running your M18 tools hard, every day, and you're tired of a standard XC5.0 losing steam before the job's done. It's a straightforward upgrade: same platform, more usable power.\u003c\/p\u003e\n\u003c\/div\u003e\u003c\/details\u003e\n\n\u003cdetails id=\"product-benefits\" class=\"acc\"\u003e\u003csummary\u003e\u003ch2\u003ePower That Doesn't Fade\u003c\/h2\u003e\u003c\/summary\u003e\u003cdiv class=\"acc-body\"\u003e\u003cdiv class=\"row\"\u003e\n\u003cdiv class=\"img\"\u003e\u003cimg src=\"https:\/\/www.milwaukeetool.com\/--\/web-images\/sc\/c0f42441677846faa21864591e91bdd8\" alt=\"Milwaukee 48-11-1855 M18 REDLITHIUM HIGH OUTPUT XC5 Battery pack rated PWR Level 3 on the M18 REDLITHIUM Power scale\" class=\"tnblock-img\"\u003e\u003c\/div\u003e\n\u003cdiv class=\"copy\"\u003e\n\u003cp\u003eStandard XC batteries can fade under high-draw tools right when you need consistent power the most.
