10 Best Milwaukee Battery 2025 in the United States

The Milwaukee 48-11-1852 M18 REDLITHIUM XC is an 18V lithium-ion battery pack with a 5 amp-hour capacity, designed to provide extended run time for power tools. It offers about 20% more power and 2.5 times longer operating time compared to standard batteries in the same line, making it a strong choice for longer work sessions without frequent recharges.

This battery is compatible with over 60 Milwaukee M18 cordless tools, providing plenty of flexibility if you already own or plan to buy other M18 products. The pack comes with two batteries, which is convenient for swapping when one runs low. It weighs around 3 pounds, so it is reasonably portable but not the lightest option available. The build quality is described as best-in-class, promising good durability for tough job site conditions.

This battery is well-suited for users who want reliable, long-lasting power for Milwaukee cordless tools, particularly those performing extended or heavy-duty tasks.

The MilwaukeeTool 48-11-1862 M18 Lithium-Ion High Output 6.0Ah Battery Pack is designed for power tool users seeking reliable and efficient battery performance. With a voltage that supports various Milwaukee tools, this battery pack offers a solid 6.0Ah capacity, ensuring longer runtimes for demanding tasks. The lithium-ion technology provides a consistent power level throughout the discharge cycle, which is great for both light and heavy-duty applications. Durability is another strong point, as Milwaukee is known for producing robust products, and this battery is no exception, often withstanding tough job site conditions.

The two-pack option also offers good value, as it allows users to keep one battery charged while the other is in use, minimizing downtime. The charge time is reasonable for lithium-ion batteries, making it convenient for users who need to get back to work quickly.

On the flip side, while the batteries are highly compatible with most Milwaukee tools, they may not fit well with products from other brands, limiting versatility for users with mixed-tool setups. Additionally, the weight of the battery, at 2.3 pounds, could be cumbersome for some users during extended use, especially in handheld tools. The price point is generally higher than some budget alternatives, which might be a consideration for casual users or DIYers who don’t need the same level of power and durability.

The Milwaukee 48-59-1850 M18 RED LITHIUM XC 5.0 Ah Batteries paired with the 48-59-1812 M12 and M18 Multi Voltage Charger is a solid choice for those needing reliable power on the job. These 18-volt lithium-ion batteries offer a high capacity of 5.0 amp-hours, meaning they can run for a long time between charges, which is great for heavy-duty use. One standout feature is the REDLINK Intelligence, which ensures optimal performance and protects against overloads by communicating between the tool, battery, and charger.

Additionally, the onboard fuel gauge helps you monitor the remaining runtime, minimizing unexpected downtimes. These batteries perform well in various weather conditions, providing steady power even in extreme environments. They are compatible with all tools in the M18 line, adding versatility to your toolkit. The charger supports both M12 and M18 batteries, making it a convenient addition if you use multiple Milwaukee tools.

On the downside, the kit doesn’t include additional batteries, which might be a drawback for those needing more spares. The batteries and charger are a bit on the heavier side at nearly 5 pounds, which could be tiring during extended use. Despite these minor drawbacks, the batteries are known for their durability and come with a solid warranty. This kit is particularly beneficial for professionals in construction or heavy-duty DIY enthusiasts looking for reliable, long-lasting battery performance.
