Key Features of Milwaukee Batteries

Advanced REDLITHIUM Technology: Milwaukee batteries feature REDLITHIUM technology to deliver consistent power, extended runtimes, and improved durability. REDLINK electronics provide overload protection and intelligent battery management, ensuring your tools and batteries are protected during intensive use.
Versatile M12 and M18 Battery Systems: For lightweight cordless tools and more demanding applications, choose compact 12V M12 batteries or powerful 18V M18 batteries. The two systems offer a variety of battery capacities, allowing you to balance runtime, weight, and performance. The batteries for compatible tools in the M12 and M18 systems are interchangeable.
HIGH OUTPUT and FORGE Performance: Milwaukee HIGH OUTPUT batteries deliver more power and operate cooler under heavy loads than standard REDLITHIUM packs. With the advanced cell technology, improved durability, and rapid charging capabilities of selected M18 FORGE batteries, you can maximise performance and reduce downtime in demanding applications.

Choosing the Right Milwaukee Battery

It is important to consider your cordless tool platform, the type of work you perform, and the amount of runtime you need to get the best Milwaukee battery. Getting the best performance out of your Milwaukee tools requires understanding the difference between Milwaukee's battery ranges.

Milwaukee M12 Batteries: Milwaukee M12 REDLITHIUM batteries are made for the brand's compact 12V cordless tools. They're a popular choice among electricians, plumbers and other tradespeople who need lightweight tools for working in tight spaces. With several capacities available, including HIGH OUTPUT models, you can choose a battery that suits your tools and the amount of runtime you need.

Milwaukee M18 Batteries: Milwaukee M18 batteries are compatible with the brand's 18V cordless tools, including combi drills, impact drivers, grinders, saws and garden equipment. Smaller batteries are useful for everyday jobs where weight matters, while higher-capacity options are better suited to longer jobs where you don't want to keep stopping to swap batteries.

Milwaukee HIGH OUTPUT and FORGE Batteries: For jobs that put more strain on your tools, Milwaukee HIGH OUTPUT and FORGE batteries offer extra power and improved heat management compared with standard batteries. They're particularly useful when using grinders, circular saws and other power-hungry tools for extended periods. Selected FORGE models also support faster charging with compatible Milwaukee chargers.

Milwaukee Batteries FAQs

What is the difference between Milwaukee M12 and M18 batteries?

The biggest difference is the voltage and the tools they fit. M12 Milwaukee batteries are designed for smaller 12V tools, making them a good choice for lighter work and jobs where space is limited. M18 batteries are made for Milwaukee's 18V range, which includes larger tools used for more demanding work. M12 and M18 batteries aren't interchangeable, so you'll need to make sure you're buying the right one for your tool.

What does Ah mean on a Milwaukee battery?

Ah stands for ampere-hours and tells you how much charge a battery can hold. Generally, the higher the Ah rating, the longer the battery will last between charges. For example, a 5.0Ah battery will usually give you more runtime than a 2.0Ah battery when used with the same tool. Keep in mind that higher-capacity batteries can be heavier, so a smaller battery might be more comfortable for lighter jobs.

What is the difference between REDLITHIUM, HIGH OUTPUT and FORGE batteries?

REDLITHIUM Milwaukee batteries are a reliable option for everyday use, offering good runtime and performance across a wide range of cordless tools. HIGH OUTPUT batteries are built for more demanding jobs, providing extra power while running cooler under heavy loads. FORGE batteries take things further with newer battery technology, improved performance and faster charging on compatible chargers. The best choice depends on the tools you're using and how demanding the work is.

Are all Milwaukee M18 batteries compatible with M18 tools?

Yes, Milwaukee M18 batteries are designed to work with tools across the M18 range. This includes standard REDLITHIUM batteries as well as HIGH OUTPUT and FORGE models. If you already own M18 tools, you can buy additional batteries or upgrade to higher-capacity models without needing to replace your tools. Just remember that M18 batteries won't fit Milwaukee M12 tools.

How long does a Milwaukee battery take to charge?

It depends on the size of the battery and which charger you're using. Smaller batteries will generally charge faster than larger ones, while Milwaukee Rapid Chargers and Super Chargers can reduce charging times considerably. For example, an M18 FORGE 6.0Ah battery can reach 80% charge in around 15 minutes when used with the compatible M18 Dual Bay Super Charger. It's worth checking the battery and charger specifications before buying to see how long charging will take.

How long do Milwaukee batteries last?

There's no fixed lifespan for a Milwaukee battery, as it depends on how often you use it and how well you look after it. Frequent heavy use, extreme temperatures and poor storage conditions can all affect how long a battery lasts. Milwaukee REDLITHIUM batteries include built-in electronics that help protect against overheating and overloading. Keeping your batteries somewhere cool and dry, and using the correct charger, can help keep them working well for longer.

Can I charge M12 and M18 batteries with the same charger?

Yes, but you'll need a charger that supports both battery systems. The Milwaukee M12-18 FC Rapid Charger, for example, can charge both M12 and M18 batteries, so you won't need separate chargers for each range. This is particularly handy if you use a mixture of 12V and 18V Milwaukee tools. Not every charger supports both systems, though, so always check before purchasing.
