Battery Makita 18V 3.0 Ah Lithium-Ion LXT BL1830B

Contents of the Makita 18V LXT Battery

This product offers you a lightweight, high-performance battery for comfortable and optimal use of your Makita 18V cordless tools.

Makita 18V LXT 3.0 Ah Lithium-Ion Battery- Lightweight compact battery designed to offer an optimal balance between reliable autonomy and operational comfort with a reduced weight of only 450g, equipped with a 4-level LED indicator to monitor the state of charge, an intelligent electronic protection system against overload, overheating and over-discharge, with a robust compact construction resistant to the daily conditions of demanding professional and DIY use.

Advantages of the Makita 18V LXT 3.0 Ah Battery

Exceptional Lightness and ComfortThe ultra-light weight of just 450g, compared to high-capacity 5.0 Ah (660g) or 6.0 Ah (760g) batteries, significantly reduces fatigue during extended use, which is particularly critical for work at height, ceiling installations, overhead work, or applications requiring precise, repetitive handling of compact tools. This exceptional lightness considerably improves the balance and maneuverability of your Makita compact tools, optimizing precision, comfort, and operational efficiency for all-day use without excessive arm, wrist, or shoulder fatigue.

Reliable and Suitable AutonomyThe 3.0 Ah battery capacity offers reliable runtime perfectly suited to Makita compact tools and light to medium daily applications: approximately 450 to 550 holes in hardwood with a compact drill/driver, or 90 to 120 cuts in 2x4 lumber with a jigsaw. This capacity represents the optimal balance for users who prioritize lightweight performance without compromising on the runtime needed to complete most daily tasks without frequent recharging, maximizing operational comfort and efficiency.

Ultra-Fast ChargingOne of the major advantages of the 3.0 Ah capacity is its exceptionally fast charging time of just 30 to 45 minutes with a Makita rapid charger, significantly faster than the high-capacity 5.0 Ah (45-60 minutes) or 6.0 Ah (55-70 minutes) batteries. This ultra-fast charging allows for more frequent and flexible battery rotations, minimizing downtime even when you only have one or two batteries, which is particularly beneficial for DIY enthusiasts or small professional teams.

First Use

1. Initial Inspection- Unpack your Makita 18V LXT 3.0 Ah battery and visually inspect it to ensure no damage has occurred during transport. Check that the compact electrical contacts are clean and free of dust or debris that could affect the connection.
2. Initial Full Charge- Before first use, fully charge the battery for approximately 45 minutes with a compatible Makita 18V charger. This initial fast charge optimizes the capacity and lifespan of your compact lithium-ion battery.
3. Functionality Test- Insert the battery into a compatible 18V LXT tool until you hear the locking click. Press the LED indicator button to check the charge level and confirm that all four lights illuminate, indicating a full charge.
4. Comfort Rating- Note the remarkable lightness of only 450g and the optimal balance of your tool equipped with the 3.0 Ah battery. This ultra-low weight will transform your operational comfort during prolonged use, particularly for work at height or repeated precise applications.

Regular Maintenance

Monthly Checks

• Inspect the compact electrical contacts and clean them gently with a dry cloth if necessary.
• Check the overall condition of the compact case for cracks or damage.
• Test the 4-level LED indicator to ensure it is working correctly.
• Make sure the ventilation openings are not blocked by debris

Load Management

• Recharge the battery before it is completely discharged to optimize its lifespan.
• Use only certified 18V compatible Makita chargers
• Enjoy ultra-fast charging in 30-45 minutes for optimal rotation
• Avoid leaving the battery completely discharged for extended periods.

Performance Monitoring

• Note any significant decrease in characteristic autonomy
• Monitor the temperature during use
• Immediately replace any battery that shows signs of swelling, leakage, or abnormal behavior.

Cleaning and Maintenance

Clean the exterior of the Makita compact battery with a slightly damp cloth after use on dusty job sites, taking care to avoid getting water inside the electrical connectors. Never use solvents, gasoline, or harsh chemicals that could damage the compact casing.

For electrical contacts, use a pencil eraser or a dry cloth to gently remove any oxidation or buildup of metallic residue. Ensure the contacts are completely dry before inserting the battery into a tool or charger to prevent short circuits.

Regularly inspect the ventilation openings and use low-pressure compressed air to remove any accumulated dust. Never attempt to open the battery casing, as this will void the warranty and pose a safety risk.

Precautions for Use

Never expose the Makita 18V LXT battery to extreme temperatures above 50°C or below -20°C, as this could damage the lithium-ion cells and significantly reduce its performance. In particular, avoid leaving the battery in closed vehicles during the Quebec summer.

Avoid strong shocks, drops, and impacts that could damage the compact internal structure or the electronic protection system. Although the casing is robust, always handle the battery with care and store it in a secure location.

Never use a battery that shows signs of physical damage, cracks, swelling, or leakage. If you notice any of these problems, stop use immediately and contact Polar Industrial Equipment for advice on safe disposal and replacement.

Keep the battery away from flammable materials and never charge it near heat sources or in confined spaces without adequate ventilation. Never immerse the battery in water or any other liquid.

Storage Tips

Store your Makita 18V LXT battery in a cool, dry place, ideally at an ambient temperature between 15°C and 25°C, away from direct sunlight and excessive humidity which could cause corrosion on the electrical contacts.

For extended storage of more than one month, maintain the battery at a charge level of approximately 40 to 60% (around 50%) rather than fully charged or completely discharged. Storing the battery fully charged or completely discharged can reduce its overall lifespan and capacity.

Use the original packaging or a protective case to prevent accidental contact between the electrical terminals and metal objects that could cause a dangerous short circuit. Although compact, the 3.0 Ah battery can deliver a high current in the event of a short circuit.

Check and recharge the battery at least every 3 months, even if it is not in use, as lithium-ion batteries undergo a natural self-discharge of approximately 1 to 2% per month. This practice maintains its electrochemical health and ensures it is ready for immediate use.
