Each pack is built for heavy-duty use, runs cooler, and performs in cold-weather climates. Milwaukee's REDLINK Intelligence protects the battery from overloads through total system communication between tool, battery, and charger, and discharge protection helps prevent cell damage. An integrated temperature management system and individual cell monitoring help maximize each battery's life, and an onboard fuel gauge shows remaining runtime. Both packs are fully compatible with all 200+ Milwaukee M18 solutions.\u003c\/p\u003e\n    \u003cp\u003eThis 2-pack makes sense for users running Milwaukee M18 tools in shops or jobsites where
