Milwaukee 48-59-1812 M12/M18 Multi-Voltage Charger with Onboard Fuel Gauge

Versatile charging for 12V and 18V Milwaukee batteries

On job sites that run a mix of 12V and 18V tools, the Milwaukee 48-59-1812 charger offers a flexible, compact solution. It supports one 12V pack and one 18V pack at the same time, letting you keep two essential tools powered without juggling multiple chargers. The sleek, low-profile design fits neatly on a bench or tool cart, reducing clutter and helping you move efficiently from task to task.

Smart charging with protection and efficiency

Inside this charger, an advanced battery communication system tracks how much energy has been delivered. As a battery approaches full charge, the charger subtly reduces output to help manage heat and conserve energy. An onboard fuel gauge and side LED indicators provide at-a-glance status, so you know when a battery is charging, full, or in need of maintenance. This combination of real-time monitoring and clear status signals supports safer operation and more predictable tool performance on the job.

• DUAL CHARGING: charges 18V and 12V Milwaukee batteries within a single unit.
• SEQUENTIAL CHARGING: each battery receives focused charging power in turn for reliable results.
• BATTERY COMMUNICATION: monitors charged energy and adjusts output to optimize efficiency.
• FAST ACTING: compact packs can be fully charged in about 30 minutes; extended-life packs in roughly 60 minutes.
• INDICATOR LIGHTS: clear signals show charging, full charge, or maintenance needs at a glance.

Real-world benefits on the job

Whether you’re wrapping up a framing phase or moving between tasks on a remodel, this charger helps you stay productive by reducing downtime between battery swaps. The dual-slot capability means you can plan a charging cadence that keeps your most-used tools ready to go. The unit ships in bulk packaging, which is convenient for teams, shops, or fleets that stock multiple sites.

• Two-battery capacity without extra gear, saving space on the jobsite.
• Clear status indicators help you time tool use and battery swaps more effectively.
