Charger Displays a Faulty IndicatorUpdated 2 hours ago

Modern HiKOKI chargers may display flashing LEDs or fault indicators when a charging issue is detected.

Possible Causes

• Battery temperature outside normal operating range
• Internal battery fault
• Charger malfunction
• Damaged battery terminals

Resolution

• Remove the battery and allow it to cool or warm to room temperature.
• Reinsert the battery and monitor the charger indicators.
• Inspect terminals for contamination or damage.
• Test with another compatible battery if available.

If the fault indicator remains active, further investigation or replacement may be necessary.
