FAQs
What is the main advantage of the BL4040F over the standard BL4040?
The BL4040F offers approximately 35% more power output due to its tabless cell technology and enhanced cooling system, allowing it to perform better under heavy load and run cooler.
Is the BL4040F battery water-resistant?
Yes, it features WetGuard/IPX4 water resistance, meaning it is protected against splashes and light water spray.
Can I use this battery with older Makita LXT tools?
No, the BL4040F is part of the XGT 40V max system and is only compatible with Makita XGT tools and chargers. It is not compatible with the LXT platform.
How do I check the remaining charge on the battery?
The battery has a 4-LED fuel gauge. Press the indicator button to view the remaining charge level.
What does 'tabless cell technology' mean for performance?
Tabless cell technology reduces internal resistance and improves heat dissipation, leading to higher peak power, less heat generation, and improved battery efficiency and longevity.
How does the cooling system work?
The battery features an integrated cooling system and uses cells designed to run cooler, which helps maintain peak performance during extended heavy-duty use and extends the overall lifespan of the battery.
What is the recommended operating temperature for charging?
It is recommended to charge the battery in temperatures between 0°C and 40°C (32°F and 104°F).
Troubleshooting
Battery not charging
Ensure the battery is correctly seated in the charger. Check if the charger is plugged in and the power outlet is working. Clean battery terminals and charger contacts with a dry cloth.
Tool not powering on with battery
Verify the battery is fully charged and properly locked into the tool. Check if the battery is compatible with the specific tool model. Ensure the battery contacts are clean on both the battery and the tool.
Reduced runtime or power
The battery may need recharging. If recently charged, ensure the tool is not running in an extreme temperature environment. Check for any obstructions in the tool that might be causing it to draw excessive power. Consider if the task demands more power than the battery can sustainably provide for extended periods.
Battery indicator lights not functioning
Ensure the battery is properly installed. If the issue persists, the battery may require service or replacement.
