Milwaukee M18 Batteries Overview 

Now that we`ve seen what the DeWalt 20V battery line has to offer, let's take a look at the different M18 batteries in the market;

M18 1.5 Ah 

This 1.5 Ah battery has a compact and lightweight build, though it is most suitable for lightweight tasks on small tools like light drilling and screw driving. 

M18 2.0 Ah

Like its 1.5 Ah counterpart, this battery is ideal for compact tools and lightweight duties. Also, you could use it on a circular saw to make a few cuts. Besides, it is a bit more expensive because it is slightly powerful. 

M18 3.0Ah 

This XC battery has extended battery life, though they're not very common. What's more, it weighs more than 1.5Ah, and it is ideal for heavy-duty tools like rotary hammers and circular saws, thanks to their long lifetime. 

M18 4.0Ah

This is an upgrade of the 3.0XC battery, and it offers more than 30% more capacity than its 3.0 counterpart. This battery is ideal for mid-sized tools such as plumbing tools, circular saws, and rotary hammers. 

Though for the more powerful tools, the 5.0Ah battery is more suitable. 

M18 XC 5.0Ah

This high output battery delivers 67 % more power than the 3.0XC and over 20 % more power than the 4.0Ah batteries. This additional power is thanks to the lithium-ion battery upgrade. This is among the most versatile batteries in the Milwaukee M18 battery line. 

Even though it is only compatible with M18 tools, some newer products outside the M18 product line are compatible. Again, this lightweight pack comes in handy in reducing weight on OPE tools, though they might not offer as much runtime as other more powerful batteries. 

M18 6.0 Ah 

This 6.0Ah battery is not quite as standard and preferred as the 5.0 Ah battery pack. However, this battery still provides more capacity than the 4.0 and 3.0 packs when fully charged. 

M18 XC6.0

This is high output battery has a 50 % excellent power availability and 50 % cooler operation, making it the ideal pack of choice for almost all heavy-duty M18 fuel and M18 power tools. 

However, with the M18 fuel table saw, this battery is not reliable precisely if you`re utilizing it for extended periods. Meanwhile, with the new supercharger from Milwaukee, you can fully recharge it within a short while. 

M18 XC8.0 

This is an advanced battery pack delivering almost twice the amount of power offered by the 5.0 Ah`s battery pack. It has a larger build; this battery is most suitable for high output tools. However, it can still work on other devices like miter saws and rotary hammers. 

That being said, some lightweight tools usually become excessively heavy or out of balance after integrating this battery.

M18 HD12.0  

This is the most powerful battery from the M18 line offering impressive power and extended runtime. It features 216-watt hours, thus giving thrice the capacity delivered by the XC4.0 battery pack. 

It is perfect for the newest and most potent power tools like the M18 fuels chainsaw, Super Sawzall, 9-inch angle grinder, table saws, and rotary hammers.

DeWalt 20v vs Milwaukee 18v: Which one is better?

The DeWalt 20V and Milwaukee M18 battery lines have a wide range of products to suit different tools for various tasks. If you require high output DeWalt batteries, the Max XR and FREXVOLT batteries are ideal. On the other hand, if you need similar output batteries for your M18 tools, the M18 12.0HD and 9.0 Ah are ideal.

However, the DeWalt 20V is a better option since it has more batteries in various categories. For instance, the FREXVOLT pack has three different batteries, while the Max line has five different batteries. 

But it depends on the power tools you have. If you have Milwaukee M18 power tools, the M18 batteries are the way to go. On the other hand, if you have DeWalt 20V power tools, it would be best to choose a battery from this manufacturer.
