Keep it Clean

Dirt, dust, and debris can accumulate over time and affect the performance of your charger. To prevent this, I recommend wiping down the exterior of the charger with a clean, dry cloth regularly.

Debris such as sawdust or metal shavings can get caught in the charger’s ports and prevent it from working properly. To prevent this, I recommend using compressed air to blow out any debris that may be stuck in the ports. Be sure to unplug the charger before doing this.

Check the Voltage

If you notice that your charger is not working properly, it could be due to a voltage issue. Check the voltage of the outlet that you are using to ensure that it is within the charger’s voltage range. If the voltage is too high or too low, it can cause damage to the charger and prevent it from working properly.

Reset the Charger

If your charger is not working properly, try resetting it by unplugging it for a minute and plugging it back in. This can sometimes fix minor issues and get your charger working again.

Regular Maintenance

Regular maintenance can help extend the life of your charger. I recommend checking the charger for signs of rust or corrosion, and cleaning it as needed. If you notice any damage or issues with the charger, it is best to have it repaired by a professional.

When you plug in your Milwaukee M12 charger, the charger indicator lights will turn on. The number of lights that turn on will depend on the level of charge in the battery.
