Milwaukee is among the top power tool brands globally, renowned for their high-tech and innovative products suitable for various projects, whether it’s home renovation, vehicle maintenance, or job site work. Despite their excellence, like any technology, issues or defects can occur, particularly regarding the batteries and chargers’ sensitivity.

Milwaukee has crafted remarkable battery systems and introduced several battery categories. These batteries work with diverse chargers, including their high-speed super chargers. These devices feature diagnostic light indications to report on battery status: a continuous red light signifies charging in progress, while a continuous green light denotes a full charge.
Yet, the charger also alerts you of potential issues, vital given how pricy Milwaukee batteries are. A fast flashing red light indicates that the battery is too hot or cold. Lithium-ion batteries must charge at optimal temperatures to prevent damage. However, if your charger is alternating red and green lights, this signals a different concern.

Flashing red and green: what it means and how to fix it
Your Milwaukee battery charger may flash red and green for a couple of reasons. The primary cause might be an incomplete connection of the battery in the charging bay. Both the battery and the charger have matching connection points that need alignment. To resolve this, take out the battery pack and properly seat it back in the charger, applying slight pressure if needed, but be cautious not to damage anything by forcing it in.

If reconnecting the battery doesn’t solve the issue and the charger continues flashing red and green, Milwaukee advises removing the battery, disconnecting the charger for at least two minutes, and inspecting the connectors for cleanliness. They recommend using compressed air or mild soap with a damp cloth, avoiding abrasive agents or solvents that may harm plastics and insulation. Ensure all parts are dry before attempting reconnection.
If the problem persists after these steps, the battery might be faulty. In this case, contacting a Milwaukee service center is advisable, particularly if your battery remains under Milwaukee’s warranty.
