Milwaukee 9.0 battery
One of the Milwaukee replacement batteries available now for your 18V 9Ah tool is manufactured by Gerrit Batt. Powered by Li-on batteries, it offers a run time that’s 3 times longer and offers 35% more power, resulting to longer use with less frequent charging.

Again made by Gerri Batt, the Milwaukee replacement battery with a 5Ah capacity is also compatible for 18V power tools with smaller power requirements. It’s powered by high quality li-on batteries that come in a pack of 2 for every purchase, which is a very good deal.
But the great thing about these 5.0 batteries is that they have a very long life, and won’t easily get drained during use despite its smaller capacity.
Usually, smaller capacity batteries used for high power tools won’t last, but in this case, it’s surprisingly long lasting. Because of that, the frequency of charging isn’t as often for a 5Ah battery, giving it a longer lifespan.

Another feature it has it the battery indicator panel which lets you know how much power is left. Probably the best feature about this is that it can be charged or discharged without any negative impact to its capacity.

This is not the case for this Milwaukee replacement battery.

The main difference between the two is that the M18 has more advanced features, making it a “smart” battery. While both are li-ion batteries that both offer increased run time, the compact M18 has a temperature management system to ensure that no overheating happens. It also has an individual voltage management system to protect it from faulty charging or discharging. Physically, it was built to prevent it from being used with tools that are incompatible with it.

The good thing is that is prevents the user from using it with the wrong tool and causing damage, but conversely, it limits the use of the battery to those specific tools.
On the other hand, the most important thing about an XC battery is that it’s generic and can be used on the same tools as the M18 plus a lot more. It’s been observed that the XC can provide more run time for the tool plus additional torque, matching what the M18 can also provide. But take note, it doesn’t have all the extra technology and features that comes with the M18, making the M18 a better choice among the available Milwaukee replacement battery options available.
