Step 2: Test with a Different Battery

If possible, try charging a different Milwaukee M18 battery with the same charger. If that battery charges normally, the issue is likely with your original battery.

Step 3: Inspect the Battery

  • Check for visible damage such as swelling, cracks, or corrosion on the terminals.
  • If damaged, replacing the battery is recommended for safety and reliability.

Step 4: Reset the System

Unplug the charger and remove the battery. Wait 10 seconds, then reconnect everything and try charging again. This can reset the circuitry and resolve minor faults.

Step 5: Consider Battery Age and Usage

If your batteries are several years old or have been heavily used, they may have reached the end of their lifespan. Upgrading to a new battery, such as the Milwaukee 48-11-1850R 5.0 Ah XC Extended Capacity Resistant Battery, might be necessary.
