Introduction to Makita Charger Lights
When you insert a Makita battery into the charger, the series of flashing and solid lights can seem confusing. These lights are designed to communicate the current status of the charging process or alert you to potential issues. Let’s explore what each indicator signifies to help you troubleshoot effectively.
Overview of Makita DC15SD and DC18RC Chargers
While this guide primarily discusses the Makita DC15SD model, similar principles apply to the DC18RC charger, which offers advanced features and different indicator signals.
Watch the Charger in Action
For a visual demonstration, check out our instructional video below that showcases the various lights and what they mean during different charging scenarios.
Makita DC15SD Charger Indicators
Flashing Green Light
This light appears when the charger is plugged into power but no battery is inserted. It indicates standby mode, ready to accept a battery for charging.
Solid Red Light
A steady red light signifies that the battery is actively being charged. Specifically, it indicates the battery charge level is below 80%, so the charger is working to replenish the power.
Solid Red and Green Lights
If both the red and green lights are illuminated simultaneously, the battery is between 80% and 99% charged. The charging process is ongoing, but the battery is nearing full capacity.
Solid Green Light
A continuous green light confirms that the battery has been fully charged to 100% and is ready for use.
Warning and Error Indicators
- Flashing Red Light: Indicates the battery is overheating. Remove the battery immediately to allow it to cool down before retrying.
- Both Lights Flashing: Signals a fault with the battery or charger, such as damage or incompatible components. Disconnect and inspect for issues.
Indicators for Makita DC18RC Charger
No Lights On
If no lights appear when the charger is plugged in, it likely isn’t receiving power. Ensure the charger is properly connected to a functional power outlet, and check the circuit breaker or fuse.
Flashing Green Light
A single flashing green light indicates the charger is in standby mode, ready to accept a battery for charging.
Solid Red Light
This indicates charging is underway, with the battery below 80%. The process is progressing normally, and a melody sound confirms the start and completion of charging.
Red and Green Lights Simultaneously
When both lights are solid, the battery is over 80%. You can choose to remove the battery now or wait until the green light indicates full charge.
Yellow Warning Lights
- Flashing Yellow: Represents a cooling issue, such as the cooling fan malfunctioning or dust clogging the vents. The battery may still charge but expect longer charging times.
- Solid Yellow and Red: The battery is conditionally charging, often due to high or low temperature, or the battery being fully charged or over-discharged. Charging may be delayed or take longer.
- Alternating Red and Green: Implies a defective battery. Remove and reinsert the battery or replace it if issues persist.
Common Troubleshooting Tips
- Ensure the charger is plugged into a working power outlet with no tripped circuit breakers.
- Check for blown fuses in the power plug and replace with a 13amp fuse if necessary.
- Clean dust from vents and cooling fans to prevent overheating or cooling issues.
- If the charger displays persistent error lights, consider professional repair or replacement.
