For years, the Milwaukee M18™ REDLITHIUM-ION™ battery has set the standard for cordless tool power and runtime. But Milwaukee, ever the innovator, has raised the bar once again with the introduction of their new FORGE™ battery platform. Here at WGM, we're excited to offer this cutting-edge technology, and we're here to explain why it's a significant leap forward for both professionals and domestic users.

What Makes FORGE™ Different?

The new FORGE™ batteries aren't just a simple capacity increase; they represent a fundamental upgrade in battery technology.

• More Power, Less Weight: FORGE™ batteries deliver a similar power output to Milwaukee's HIGH OUTPUT™ range but in a smaller, lighter package. This is a game-changer for high-demand tools like chainsaws and lawnmowers, where sustained power is crucial and a lighter tool reduces user fatigue.
• Faster Charging with the Super Charger: This is arguably the most impressive feature. When paired with the Milwaukee Super Charger, a FORGE™ 8.0Ah battery can reach an 80% charge in just 35 minutes! This dramatically reduces downtime on the job site or in your garden, allowing you to get back to work faster.
• Enhanced Durability: The new battery design includes a robust housing that provides enhanced protection against common oils, greases, and solvents, as well as dusty and wet environments.

Is it Worth Upgrading to FORGE™?

If you're already invested in the M18™ system, you might be wondering if it's worth the switch. Here’s a quick breakdown:

• Compatibility: All FORGE™ batteries are fully compatible with your existing M18™ cordless tools and chargers. You don't need to replace your entire collection.
• For High-Drain Tools: If you frequently use high-demand tools like chainsaws or lawnmowers, upgrading to a FORGE™ battery will provide a noticeable performance boost and significantly reduce charging time.
• For All-Day Work: For professionals who need to maximise productivity, the rapid charging of the FORGE™ system means you can run an entire workday on a minimal number of batteries. This is a key benefit for new tools like the 2025 Milwaukee hedgecutters and the new long-reach models, which are designed to maximise the power and run-time of the new batteries.

The FORGE™ system is more than just a new battery—it's a productivity multiplier. It allows for a more efficient workflow, less downtime, and ultimately, a more powerful user experience.
