  • M 18 Ford batteries at excellent purchase
Sure, love the M 18 Milwaukee batteries. Very reliable product to use the power by M 18 Milwaukee tools. The forge brand here gives extended, run time and more life and XC M 18 batteries it replaced.

  • Take No Prisoners
The Milwaukee M18 RedLithium Forge 12.0 Battery kicks ass & takes no prisoners. Long lasting & even when it’s down to the lowest charge it’s still rolling hard. Get it while you can @ this price ($190-$200) because that’s $80/$90 cheaper than Home Depot. Highly recommend

  • Pricey, but lots of power.
This thing is a monster. I used it in a weed trimmer for about a half an hour and it was still on 4 bars.

  • Beast of a Battery
Massive. Heavy. Absurdly powerful and borderline overqualified for polite society. Yes, it weighs enough to remind you that you are not spending enough time at the gym, but that’s the price of having your blower and impact wrench suddenly behave like they’ve been personally offended by resistance. Runtime is generous, output is relentless, and the tools just… don’t slow down. If you’re looking for subtlety, this isn’t it. If you’re looking for “press trigger, solve problem immediately,” welcome home. ... show more

  • Life is not the longest but does the job
I have a powerful blower. It runs it at full power for about 12-15 min
