Inspect Your Battery
- Remove the battery from the tool and inspect the contacts for dirt, corrosion, or damage.
- Clean contacts with a dry cloth or a soft brush if dirty.
- Look for swelling, cracks, or other physical damage — if present, replace the battery.
Test with a Different Charger
If possible, use another compatible charger to see if the battery charges. If it does, your original charger may be faulty. If not, the issue may lie with the battery or the tool’s charging port.
Reset and Recondition the Battery
- Fully discharge the battery using the tool or by running it down safely.
- Recharge it fully using the original charger.
- Repeat this cycle 2-3 times to help restore battery capacity.
Consider Replacement
If after these steps your battery still won’t charge, it may be time to replace it. Check for compatible Milwaukee batteries such as the Milwaukee 48-11-1850R 5.0 Ah XC or the REDLITHIUM HIGH Output XC 6.0Ah Battery Pack, which provide reliable power and performance.
