Makita Power Tool Flashing Red and Green: How to Fix It

Q: Why does my Makita battery flash red and green?

Flashing red and green lights indicate the battery temperature is outside the safe charging range (either too hot above 104°F or too cold below 50°F). This is a safety feature to prevent battery damage.

Q: How long should I wait for a hot Makita battery to cool down?

Allow 30-60 minutes for a hot battery to cool to room temperature. Extremely hot batteries from heavy use may require longer cooling time before they can be safely charged.

Q: Can I charge my Makita battery in cold weather?

No, Makita batteries should not be charged when the temperature is below 50°F (10°C). Bring the battery to room temperature before attempting to charge it to avoid damage.

Q: What temperature range is safe for charging Makita batteries?

Makita batteries should be charged in temperatures between 50°F and 104°F (10°C to 40°C). Charging outside this range can damage the battery cells and reduce lifespan.

Q: Is it normal for Makita batteries to get hot during use?

Yes, batteries naturally heat up during heavy use. However, if a battery becomes too hot to handle comfortably, stop using the tool and allow the battery to cool before continuing work or charging.

Abstract

When your Makita power tool or charger displays flashing red and green lights, it indicates the battery temperature is outside the safe charging range - either too hot or too cold. This safety feature prevents damage to your battery and ensures optimal performance.
