Frequently Asked Questions

How long does a Milwaukee M18 battery take to charge?

Charge time depends on the charger and battery capacity. Milwaukee Super Charger (M18SC6) charges a 12.0Ah battery in approximately 60 minutes. Standard M18SC4 charger takes about 90 minutes for a 5.0Ah pack.

Can I charge a Milwaukee REDLITHIUM battery on any M18 charger?

Yes — all REDLITHIUM batteries are compatible with the full Milwaukee M18 charger range. The REDLITHIUM+ batteries require a Milwaukee REDLITHIUM USB charger or compatible M18 charger.

What does it mean when a Milwaukee battery gets warm during charging?

Some warmth during charging is normal. Excessive heat (too hot to touch) suggests a cell fault or charging outside the safe temperature range. Remove the battery and allow it to cool.
