Frequently Asked Questions
What does a flashing red light on a Makita charger mean?
A slow flashing red light typically indicates a temperature hold — the battery is too hot or cold. A rapid flashing red light indicates an abnormal battery (defective cells or over-discharged pack).
Can a Makita charger go bad?
Yes — Makita chargers can fail, especially if used in wet conditions or dropped. Test with a known-good battery. If the charger rejects all batteries, it needs replacement.
Is the Makita Star Protection charger error the same as a standard error?
Makita Star Protection batteries and chargers communicate more advanced data including cell voltage and temperature. Error lights on Star Protection chargers may indicate more specific battery health information than older models.
