Makita 18V LXT Lithium-Ion Battery

When I first got my hands on the Makita 18V LXT Lithium-Ion Battery (BL1850B), I was eager to put it through its paces. This 5.0Ah powerhouse promised to extend the runtime of my Makita tools significantly and boast a few advanced features that piqued my interest. As someone who relies heavily on cordless tools for various projects, a reliable and long-lasting battery is a must.

Design and Build Quality

Straight out of the box, the BL1850B feels solid. Its impact-resistant outer case and shock-absorbing inner liner give it a reassuring heft, suggesting it’s built to withstand the occasional drop or bump in a busy workshop. The integrated L.E.D. battery charge level indicator is a handy addition, allowing me to check how much juice is left without having to guess or swap it into a tool.

One thing to note about the BL1850B is its compatibility. It’s designed to work exclusively with Makita’s Star Protection tools, which means if you have older Makita tools (pre-Star Protection), this battery might not fit. This wasn’t an issue for me as all my tools are relatively new, but it’s something to consider if you’re looking to update your battery arsenal.

Performance and Runtime

The standout feature of the BL1850B is its runtime. Compared to older 3.0Ah batteries, the 5.0Ah capacity means it lasts significantly longer—up to 65% more run time per charge. This was evident when I used it with my Makita circular saw. I could get through an entire day’s worth of cutting without needing to recharge. This is a significant upgrade from having to swap out batteries multiple times during a project.

Charging the battery is also quick, with a full charge taking around 45 minutes. This rapid recharge time means less downtime, which is crucial during larger projects. I paired it with an older Makita charger, and it worked flawlessly, so compatibility with older chargers (within reason) seems to be well-supported.

Usability and Features

In terms of usability, the BL1850B is straightforward. The battery slides easily into my tools, locks firmly in place, and maintains a constant connection, so I never experienced any power loss during usage. I appreciate the built-in protection controls that prevent overloading and overheating. Even during prolonged use, the battery never got excessively hot, which can be a concern with high-capacity batteries.

Another feature worth mentioning is its performance in extreme temperatures. Working in a cold garage, I didn’t notice any drop in performance, which speaks to the battery’s resilience. Additionally, the battery resists self-discharge, maintaining its charge during periods of inactivity. I left it unused for a few weeks, and it still held a full charge when I returned. This is particularly useful for those who might not use their tools daily.

Practical Applications

I used the BL1850B with a variety of my Makita tools, including a leaf blower, drill, and impact driver. In each case, the battery provided consistent power and long-lasting performance. For example, when using the leaf blower, the high current needs were met with ease, and I didn’t notice any drop in performance even towards the end of the battery’s charge.

For those who use USB-powered devices, the battery also works with the Makita DEBADP05 adapter, which has two USB ports. I tested this feature in my camper, powering low-voltage lights without drawing from the starter battery. This versatility adds another layer of usefulness to an already impressive battery.

Drawbacks

While the BL1850B has numerous strengths, it’s not without its downsides. The battery is slightly heavier and bulkier than the smaller capacity versions. This added weight can be noticeable, especially during extended use. Some might find it cumbersome, particularly if they’re accustomed to lighter batteries. However, for me, the trade-off for extended runtime is worth the slight increase in weight.

Another potential drawback is the price. Makita batteries are generally more expensive than off-brand alternatives. However, in my experience, the performance and reliability of the BL1850B justify the cost. After trying cheaper alternatives that either arrived dead or failed after a few recharges, I’m convinced that spending a bit more on a genuine Makita battery is a worthwhile investment.

Final Thoughts

Overall, the Makita 18V LXT Lithium-Ion Battery (BL1850B) is a robust, high-performing power source that enhances the efficiency and longevity of compatible Makita tools. Its long runtime, quick recharge time, and durable design make it a valuable addition to any workshop. The added features, such as the L.E.D. charge indicator and protection controls, further enhance its appeal.

Would I recommend the BL1850B? Absolutely. For anyone heavily reliant on cordless tools, this battery offers reliability and performance that are hard to beat. Its slightly higher price is justified by the quality and longevity it provides. Just ensure compatibility with your tools to fully benefit from what this battery has to offer.
