Milwaukee M18 REDLITHIUM FORGE XC6.0 Battery Pack

Milwaukee's M18 REDLITHIUM FORGE XC6.0 Battery Pack is a remarkable addition to the M18 lineup, promising to deliver 12.0 power in a compact and lightweight design. Having put this battery through its paces in various demanding tasks, I’ve discovered both its strengths and a few areas where it might leave some users wanting more.

First Impressions and Build Quality

Right out of the box, the M18 FORGE battery impresses with its robust build. The housing feels solid and is designed to resist oils and solvents, which is crucial for any tool that will see heavy use in demanding environments. Milwaukee has also enhanced the battery strength indicator with a soft push cover and horizontally positioned LED lights, making it easier to gauge the battery life even in direct sunlight. The overall footprint of the battery is slightly larger than the 5.0Ah packs but smaller than the 6.0 High Output (HO) batteries, allowing it to fit comfortably in most of my existing M18 tools.

Performance and Power

In terms of power, the M18 FORGE XC6.0 does not disappoint. It boasts a higher discharge rate, which translates to a noticeable bump in performance. For instance, when using my Milwaukee circular saw and 1" SDS plus D-handle rotary hammer, I observed an increase in power that made cutting and drilling tasks more efficient. This higher discharge rate means the battery delivers more power to the tool, resulting in enhanced performance.

However, this comes with a trade-off. The increased power output means that the battery does not last as long as some might expect, especially when compared to the 12.0 HO batteries. For example, while using my M18 backpack vacuum, the battery performed admirably but required recharging after a shorter period compared to the 12.0 HO battery. The good news is that the battery charges incredibly fast. Using the M18 Dual-Bay Simultaneous Super Charger, I could get the battery to 80% in just 15 minutes and fully charged in about 25 minutes. This rapid charging capability is a game-changer, effectively mitigating the shorter runtime.

Versatility and Compatibility

One of the standout features of the M18 FORGE XC6.0 is its compatibility with over 250 M18 tools. This makes it a versatile option for anyone heavily invested in the Milwaukee ecosystem. From my experience, the battery performed well across a range of tools, including the M18 quik-lok string trimmer and the Milwaukee rubber broom attachment. The consistent power output and quick recharge times meant I could keep working with minimal downtime.

Practical Use Cases

In practical terms, the M18 FORGE XC6.0 shines in scenarios where you need a balance of power and reduced weight. For instance, while working as an arborist, the lighter weight of the FORGE battery made a noticeable difference when using my chainsaw for extended periods. The reduced arm fatigue was a significant benefit, although I did wish for a bit more runtime in some cases.

For industrial applications, such as using impacts, grinders, and portabands, the battery’s performance was impressive. My grinder, which often shuts off due to power limitations, ran more smoothly and with fewer interruptions. This battery's ability to deliver consistent power makes it ideal for high-demand tools that require reliable performance.

Limitations

Despite its many strengths, the M18 FORGE XC6.0 is not without its limitations. The most notable is the shorter runtime compared to the 12.0 HO batteries. This is particularly evident in tools that require sustained power over longer periods, such as the Milwaukee light and leaf blower. In these cases, the FORGE battery does not last as long, which might be a deal-breaker for some users.

Another point to consider is the cost. The battery and the supercharger can be quite an investment, especially if you need multiple units for continuous work. While the rapid charging times help offset the shorter runtime, the initial outlay could be a deterrent for budget-conscious users.

Final Thoughts

Overall, the Milwaukee M18 REDLITHIUM FORGE XC6.0 Battery Pack is a robust and high-performing addition to the M18 lineup. Its compact size, lightweight design, and rapid charging capabilities make it an excellent choice for professionals who need reliable power in a smaller package. While it may not match the runtime of the 12.0 HO batteries, its performance, versatility, and quick recharge times make it a valuable asset on the job site.

Recommendation

I would recommend the M18 FORGE XC6.0 Battery Pack for anyone already invested in the Milwaukee M18 ecosystem, particularly those who need a balance of power and portability. Its rapid charging capability and consistent performance make it ideal for high-demand tasks, although users should be aware of the shorter runtime compared to larger capacity batteries. For those who prioritize power and reduced weight over extended runtime, this battery is a solid investment that delivers on its promises.
