Thanks for the link!
What would you need a 9 amp battery for? I have the 5 amp batteries and they run forever and have tons of power. Not sure what M18 tool milwaukee makes that would need a 9 amp battery? Also not sure I would want to carry it around for very long.
High demand tools.
Having 3 sets of cells means these batteries can deliver more power than XC and compact batteries. That also means they can run a little cooler, in theory meaning greater longevity and longer runtime.
These batteries are designed to match with the biggest and most powerful M18 tools, such as the new rotary hammer, Super Hawg, and things like that.
Also, note that the batteries are LONGER. The batteries seem to be staggered, reducing the height but growing the length.
Some new tools, such as the LED tripod light, are designed to accommodate the new 9Ah pack. Nobody is going to want to pair it with compact and lightweight tools.
You're not going to want to attach a 9Ah battery to something like a drill or impact driver.
