Milwaukee 12V Kit, 4.0Ah Batteries and Charger for M12 Tools - Pack of 2

Each battery in the set is a 12V M12 lithium‑ion cell rated at 4Ah, designed for extended runtime across Milwaukee’s M12 tool lineup.

These batteries use Milwaukee’s M12 interface, so they’re compatible with the entire M12 tool system. The included charger is designed to recharge the two batteries provided in the kit and works with other M12 batteries as well.

Charge times vary by charger and battery state, but with two 4Ah packs, you can typically expect a full recharge in about 60–90 minutes per battery under normal conditions using the included charger. You can rotate batteries so one charges while you work with the other.

With the tool powered off, align the battery with the tool’s battery port and slide it in until you hear a click indicating a secure connection. Ensure the connection is fully seated before use.

Handle with care: avoid exposing to moisture, extreme heat, or direct flame; don’t attempt to open or modify the cells; store in a cool, dry place; keep away from children; use the charger provided or approved Milwaukee chargers to maintain safe charging.

Yes. The kit’s two 4Ah batteries allow you to swap one in use while the other charges, helping minimize downtime on ongoing projects.

This kit is ideal for portable, light- to moderate-duty tasks where a compact, lightweight power source is advantageous—such as woodworking, small framing, DIY fixes, cable routing, and on-site light maintenance.

Practice good battery hygiene: avoid complete discharge unless necessary, store batteries around 40% charged for long-term storage, keep terminals clean and dry, use at moderate temperatures, and periodically cycle batteries (full charge/discharge) to calibrate the gauge.

Compared to other two‑battery 12V kits offered on Fepy, the M12NRG-402 provides two 4Ah packs and a charger, delivering solid runtime for mid-range tasks. For longer runtimes, you might consider higher-capacity 6–8Ah packs if available, or kits that include faster chargers. See related listings on Fepy for alternatives such as two‑pack 4Ah kits or higher‑capacity options.
