Milwaukee MX FUEL™ REDLITHIUM™ XC406 Battery Pack

Milwaukee's MX FUEL™ REDLITHIUM™ XC406 Battery Pack has been touted as a game-changer in the realm of cordless power tools. As someone who frequently relies on high-performance tools for demanding tasks, I was eager to put this battery pack to the test. With its promise of fade-free power delivery and compatibility with all MX FUEL equipment, it seemed like a promising addition to my tool arsenal.

Design and Build Quality

The first thing I noticed about the MX FUEL battery is its robust build. The material composition, which includes impact-grade steel reinforced polycarbonate, gives it a rugged feel. This is a battery designed to withstand the rigors of a construction site. The integrated carrying handle is a thoughtful addition, making it easier to transport the 10.62-pound unit. However, the weight does make it less convenient for quick, one-handed swaps, especially compared to smaller batteries like the M18 or M12.

Performance and Runtime

In terms of performance, the MX FUEL battery pack delivers impressive power. I tested it with the MX Fuel Concrete Breaker and the MX Fuel 14" Cut-Off Saw. Both tools performed admirably, thanks to the battery's consistent power output. The fade-free power delivery is a significant advantage, ensuring that the tools operate at full capacity until the battery is depleted.

However, the runtime is a mixed bag. While the battery lasted a decent amount of time with lighter tools, it struggled with more demanding applications. For instance, using the battery with the 14" Cut-Off Saw, I found that it could only handle about 6 feet of cuts before needing a recharge. Similarly, when used with the jackhammer, the battery's performance was less than stellar, requiring multiple batteries to complete a single task. This inconsistency in runtime can be frustrating, especially when working on larger projects.

Charging and Durability

One of the standout features of the MX FUEL battery is its quick recharge time. Fully charging in just 90 minutes, it minimizes downtime, which is crucial on the job site. The onboard fuel gauge is another handy feature, allowing you to monitor the remaining runtime easily.

However, durability is where this battery pack falls short. Despite its rugged build, I encountered issues with the battery's ability to hold a charge over time. After a few weeks of use, one of my batteries started throwing error codes and wouldn't charge properly. This seems to be a recurring issue, as I've heard similar complaints from other users. Given the high cost of the battery, this lack of reliability is a significant drawback.

Compatibility and Ease of Use

The MX FUEL battery is compatible with all MX FUEL equipment, which is a definite plus. It latches into the tools easily and comes out just as smoothly, thanks to its user-friendly design. Unlike the M12 or M18 batteries, there are no small tabs or sticky latch buttons to contend with. However, the battery's size and weight can make the swapping process more cumbersome, particularly for those with smaller hands.

Cost and Value

At a premium price point, the MX FUEL battery pack is a significant investment. While it offers excellent performance and quick charging times, the inconsistent runtime and durability issues make it hard to justify the cost. For those who rely heavily on MX FUEL tools, having multiple batteries is almost a necessity, which further adds to the expense.

Final Thoughts

The MX FUEL™ REDLITHIUM™ XC406 Battery Pack has its strengths, particularly in terms of power delivery and quick recharge times. Its rugged design and compatibility with all MX FUEL equipment are also commendable. However, the inconsistent runtime and durability issues are significant drawbacks that can't be ignored.

Would I recommend this battery pack? It depends on your specific needs. If you're already invested in the MX FUEL system and require a battery that can deliver consistent power for lighter tasks, this could be a worthwhile addition. However, if you need a reliable, long-lasting battery for more demanding applications, you might want to consider other options or be prepared to invest in multiple units to ensure continuous operation.

In summary, the MX FUEL battery pack offers a mix of impressive features and frustrating limitations. While it has the potential to be a valuable tool for certain applications, its high cost and reliability issues make it a less compelling choice for those who require consistent, long-term performance.
