FAQs
Is this battery compatible with older Makita 18V LXT tools?
No, this 40V XGT battery is only compatible with Makita XGT 40V tools and chargers. It is not backward compatible with the 18V LXT system.
How do I check the remaining charge on the battery?
The battery features a fuel gauge with 4 green LEDs. Press the button on the battery to illuminate the LEDs and see the remaining charge level.
Can I use this battery in wet conditions?
Yes, the battery has WetGuard/IPX4 water resistance, providing protection against moisture and splashes, making it suitable for damp environments.
What does 'tabless cell technology' mean for performance?
Tabless cell technology uses cells with lower internal resistance, which allows for higher peak power delivery, reduces heat generation, and improves overall efficiency and battery autonomy.
How does the cooling system work?
The integrated cooling system actively manages battery temperature during operation and charging, preventing overheating and allowing for sustained high performance under heavy loads.
What is the warranty period for this battery?
Warranty information can vary by region and retailer. Please refer to your product documentation or the retailer's warranty policy for specific details.
Can I leave the battery on the charger indefinitely?
While XGT chargers are designed for smart charging, it is generally recommended to remove the battery once fully charged to prolong its overall lifespan. Avoid long-term storage on the charger.
Troubleshooting
Battery not recognized by the tool
Ensure the battery is correctly inserted and locked into place. Check if the tool's battery contacts and the battery's terminals are clean. Try a different XGT tool to rule out a tool-specific issue.
Battery charges slowly or not at all
Verify that the charger is properly connected to a working power outlet. Clean the battery and charger terminals. Ensure the battery is within the optimal charging temperature range (avoid charging in extreme heat or cold).
Reduced runtime or power output
The battery may need to be recharged. If the issue persists after a full charge, the battery's lifespan may be nearing its end, or there might be an internal fault. Ensure you are using the correct XGT charger for optimal charging.
LED indicator flashing erratically
This may indicate an error or fault condition. Consult the tool or charger manual for specific LED flashing codes. If unresolved, contact Makita service.
