Milwaukee M12 Redlithium High Output 2.5ah and 5.0ah batteries

Milwaukee created their high output batteries to provide the power needed for more powerful 18V tools such as their 1-9/16″ SDS Max rotary hammer and their first cordless 10″ miter saw. All the while M12 battery technology capped out at 3ah in a compact battery and up to 6ah for an XC battery pack, but yet those were not “high output” battery packs. Fast forward to today and we now have high output batteries in the M12 system. They consist of a high output 2.5ah compact battery shown below and a high output XC 5.0ah battery shown above.

Milwaukee says these M12 high output batteries “are pushing the tool capabilities of existing and future M12 tools”. This means you may get up to 25% more power on high demand tools (like saws for example but not limited to) and they can run up to 25% cooler as well in heavy applications they claim. If true, these are good performance measures as a battery operates better when cooler and if we can get more performance out of their available power tools, even better. I think their M12 Fuel circular saw and the M12 Hackzall’s are good candidates for these batteries as their high demand power draw would benefit the most from these. These batteries also allow Milwaukee to develop more powerful M12 tools in the future I imagine as that’s what happed to the M18 line, tools like their 10″, 12″ miter saws, table saw, and 1-9/16″ SDS Max rotary hammer were all possible with the release of M18 high output batteries. Milwaukee also says these M12 high output batteries “are resistant to oils, solvents, & greases commonly found in transportation maintenance & manufacturing environments” making them durable. These M12 high output batteries will launch November 2022 and are priced at $79 for the 2.5ah and $119 for the 5.0. The one negative about these batteries is that they are not 3.0 & 6.0 respectively or larger capacity but I assume Milwaukee is limited in what they can do on the current size of the M12 batteries as they probably can’t fit larger 21700 cells. But I do commend them for squeezing out more performance out of the M12 system with new high output batteries.

REDLITHIUM™ USB Stick Light w/ Magnet and Charging Dock (2128-22)

The new Milwaukee light is a stick light that runs on their  small Redlithium USB battery pack. This helps it remain small yet powerful enough to put out up to 550 lumens on high and 250 lumens on low. It has a thin foldout light panel that if it’s like their previous stick lights, it should give smooth even light and fit in tight spaces, like the wheel well of a vehicle for example and can attach to metalic surfaces thanks to a built in magnet for hands free operation. Battery life is rated for up to 5 hours on low and up to 2 hours on high.

It will be available in September for $99 as a baretool and $159 as a kit with a 3ah battery, USB charging dock and USB charge cord.

Why would a 10.4 volt tool need a high output?! How high is the output comparing to their regular batteries? Not the nominal but the actual output, mind you, the sustained operation, when the battery is between 95% and 40%, I bet there is little to no difference, they’re just trying to capitalize on our Ignorance in terms of electrical output possibilities. I think that this is just a gimmick, nothing more. Offering a battery with minimal benefits for motors that can’t take advantage of its capabilities, that’s the definition of a gimmick!
