Makita 18V Lithium-Ion Compact Battery

As an avid user of Makita's extensive range of cordless tools, I recently had the opportunity to test the 18V Lithium-Ion Compact Battery (BL1820B-2). This compact, lightweight battery promises fast charge times and increased run times, which piqued my interest given my frequent need for quick, reliable power on the job site.

Design and Build Quality

One of the first things I noticed about this battery is its compact and lightweight design. Weighing in at just 0.75 lbs, it’s significantly lighter than the larger 3.0Ah or 5.0Ah batteries. This makes it an excellent choice for tools where weight and balance are critical, such as drills, impact drivers, and compact routers. The reduced weight makes a noticeable difference, especially during prolonged use, reducing fatigue and making it easier to handle tools for precision work.

The battery also features an integrated LED charge level indicator, a handy addition that allows you to quickly check the battery's status. This is particularly useful when you're in the middle of a project and need to gauge whether you have enough power to finish the task or need to swap out for a fresh battery.

Performance

Performance-wise, the BL1820B-2 does not disappoint. It charges remarkably fast, reaching full capacity in about 25 minutes or less. This quick charge time is a game-changer on busy job sites where downtime can be a significant setback. I found that the battery’s 2.0Ah capacity provided ample run time for most of my tasks, from drilling and driving screws to lighter edge work with a compact router.

Despite its smaller capacity, the battery holds its charge well, even when stored for extended periods. This is thanks to its lithium-ion technology, which resists self-discharge. I was able to leave the battery on the shelf for weeks and still have it ready to go when needed, a feature that adds to its convenience and reliability.

Versatility and Compatibility

One of the standout features of the BL1820B-2 is its compatibility with Makita's extensive range of 18V LXT tools. This means you can use this compact battery across various tools without worrying about compatibility issues. I tested it with my drill, impact driver, and even a compact router, and it performed admirably with each.

For tasks that require more power or longer run times, Makita’s system allows you to switch to larger capacity batteries seamlessly. However, for lighter, precision tasks, the 2.0Ah battery strikes an excellent balance between power and weight.

Durability

Durability is another area where this battery excels. It features a shock-absorbing inner liner that provides additional protection against drops and impacts, which is a common occurrence on job sites. The build quality feels robust, and I didn't encounter any issues with the battery casing or connections during my testing period.

Value for Money

Considering its features and performance, the BL1820B-2 offers excellent value for money. While it may not be the cheapest option available, its reliability, fast charge time, and compatibility with a wide range of tools make it a worthwhile investment. The integrated charge level indicator is a small but significant feature that adds to its overall value.

Use Cases

The BL1820B-2 shines in scenarios where a lightweight, compact battery is advantageous. For instance, when using a compact router for laminate edge trimming or sign making, the reduced weight makes the tool easier to handle and control. Similarly, for overhead tasks or situations where you need to maneuver in tight spaces, the lighter battery reduces strain and makes the job more manageable.

Areas for Improvement

While the BL1820B-2 is an excellent battery, it's not without its limitations. The 2.0Ah capacity means it may not be suitable for heavy-duty tasks that require extended run times. For such applications, larger capacity batteries like the 5.0Ah or even Makita's dual-battery 36V system might be more appropriate. Additionally, while the battery gauge is a useful feature, some users might find it redundant if their tools already have built-in battery indicators.

Conclusion

In conclusion, the Makita 18V Lithium-Ion Compact Battery (BL1820B-2) is a stellar performer that lives up to its promises. Its compact, lightweight design, fast charge time, and compatibility with a wide range of tools make it an invaluable addition to any toolkit. Whether you're a professional tradesperson or a DIY enthusiast, this battery offers a perfect blend of convenience, performance, and reliability.

I would highly recommend the BL1820B-2 for anyone looking for a lightweight, fast-charging battery that doesn’t compromise on performance. It’s particularly well-suited for tasks that benefit from reduced weight and improved tool balance. While it may not be the best choice for heavy-duty applications requiring extended run times, it excels in its intended use cases and offers excellent value for money.
