Milwaukee 48-59-1812 Dual 12V/18V Battery Charger with Onboard Fuel Gauge

Flexible, on-site charging for 12V and 18V Milwaukee batteries

When your toolkit runs on both 12V and 18V Milwaukee packs, the 48-59-1812 charger delivers a versatile, jobsite-ready solution. It accepts one battery of each voltage in a single unit, letting you power two essential tools without swapping chargers mid-task.

Designed to simplify workflow, the unit automatically handles charging cycles so you don’t have to micromanage each pack. The integrated communication chip tracks how much energy the batteries have stored and dynamically adjusts output as they approach full, helping to conserve energy and prevent overprocessing when a battery is ready.

• Dual charging capability supports 18V and 12V Milwaukee lithium-ion packs, with room for one of each at a time.
• Sequential charging focuses on one battery after the other, ensuring each pack receives full charging power.
• Battery communication keeps you informed of charge status and reduces energy output as packs near full.
• Fast-acting charging delivers approximately 30 minutes for compact packs and around 60 minutes for extended-life packs.
• Indicator lights clearly show charging, full status, and maintenance needs, with an onboard fuel gauge for quick checks.

On the job, the combination of LED status indicators and the onboard fuel gauge provides a quick snapshot of how much charge remains, helping you plan tool usage and battery swaps. The charger’s compact footprint is designed for busy vehicles and crowded workspaces, so you can keep moving between tasks while staying within reach of your power source.

In short, this Milwaukee charger is built to support versatile tool setups, promote safer charging, and help you manage battery life more proactively on site. While results can vary by battery type and usage pattern, many users report smoother workflow with fewer interruptions when managing mixed voltages through a single charger.
