Milwaukee 48-11-1820 – Frequently Asked Questions

1) Is a 2.0Ah compact pack enough, or should I step up to a higher amp hour M18 battery?
At 2.0 amp hours / 36 watt hours, the 48-11-1820 is the compact end of the M18 line. It keeps weight and bulk down for drills, drivers, lights and work in tight overhead or ladder positions. For high-draw tools run all day (circular saws, grinders, rotary hammers) a higher capacity M18 pack gives longer runtime between charges. Many crews carry compacts for trim and fastening work and larger packs for cutting and demolition.
2) Will this M18 battery hold up in cold or hot weather on an outdoor jobsite?
Milwaukee's 48-11-1820 is built for all-weather performance and delivers fade-free power in extreme jobsite conditions. A temperature management system keeps the cells within their working temperature range, and individual cell monitoring controls charge and discharge to protect pack life.
3) What is the exact part number I should order for the Milwaukee M18 2.0Ah compact battery?
Order Milwaukee Tool 48-11-1820. That is the M18 REDLITHIUM 2.0Ah compact battery pack sold as a bare battery, so if you need charging capability you will also need an M18 compatible charger.
4) How do I check remaining charge on the Milwaukee M18 2.0Ah pack without putting it on a tool?
There is an onboard fuel gauge on the pack itself that displays remaining runtime, so you can check a pack in the van or on the shelf before you carry it up. Useful when you are staging several batteries for a service call.
5) What is REDLINK Intelligence on a Milwaukee M18 battery and does it matter for my tools?
REDLINK Intelligence is electronic communication between the tool, battery and charger. On the 48-11-1820 it manages output for optimized performance and shuts things down under overload, which protects the tool and the pack when a bit binds or a saw stalls. It works with the M18 tool and charger electronics, so you get that protection only on the M18 system.
