When Should I Reset Milwaukee M18 Battery?

Here are a few situations where resetting your battery might be necessary:

Lights 1-4, Flashing Quickly

When the lights on your battery pack flash rapidly in a sequence from 1-4, it indicates that the current draw is too high for charging.

You should disconnect the battery from the charger.

Once you've ensured the current draw is appropriate, you can reset the battery.

Battery Not Charging

If your Milwaukee M18 battery is not charging properly, resetting it may help.

First, try cleaning the battery contacts and the charger contacts with a dry cloth.

If that doesn't work, try resetting the battery. Then, try charging the battery again.

Sudden Power Loss

The Milwaukee M18 battery has a smart feature to protect itself and last longer. It monitors power use and its own heat.

If the tool works too hard, it might turn itself off to prevent damage. Before turning off, the tool can buzz for 2-5 seconds as a warning.

Should you encounter this, either lighten your pressure or let go of the trigger. Should the tool halt, disengage the trigger for a quick reset.

Frequent power disruptions could lead to the battery shutting down entirely. To check, press the fuel gauge button.

A single blink from the lowest light means it needs resetting.

Place the battery on its charger to reset. The lights will quickly show the battery's charge level at shutdown, ranging from one to four lights.
