The MILWAUKEE® M18 REDLITHIUM™ XC5.0 Starter Kit delivers up to 2.5X more runtime, 20% more power, and 2X more recharges than standard lithium-ion batteries. The lithium-ion battery pack features superior pack construction, electronics, and performance. The rechargeable battery also offers users 5.0 amp-hours of runtime. Each battery pack is durably built for heavy-duty use, runs cooler, and performs in climates below 0°F/-18°C. This protection routes water away from the electronics and out of the battery pack, extends the battery's run-time and life by minimizing heat, and prevents pack failures from vibration or drops. Built-in REDLINK™ Intelligence protects the battery from overloads, preventing users from damaging their cordless power tools in heavy-duty situations, while the discharge protection prevents cell damage. An integrated temperature management system and individual cell monitoring help to maximize the battery's life. In addition to the batteries, the starter kit includes the M18™ & M12™ Battery Charger.
