  • Well worth the upgrade.
Great battery. Long lasting compared to the base ones that came with my impact gun. Also allows me to use my leaf blower for an extended period of time without running out of power.

  • Big boy battery for big boy things
Yep, it’s a high-output M18 Milwaukee battery. It does its job and does it well. You need to use a rotohammer to drill some holes in concrete and you need a battery that’s going to last you the entire day? This guys got you. You tired of your wimpy batteries dying after cutting some pipe with your bandsaw or hackzall? This guys got you. This guy is on the beefier side but if you’re a big boy, you’re gonna be a-okay. ... show more

  • High power, long lasting
Very good battery. Lasts longer than previous battery. I just wish they were not so expensive. I would probably buy more often.

  • Milwaukee M18 Redlit battery 6.0
Excellent sale, product and delivery! Works fantastic as seller described!

  • Perhaps a reason this battery is discounted…
Be mindful these discounted batteries may likely all be new, but are most likely out of warranty based on manufacture date on the serial number of battery. Purchased this battery new. Packaging looked a little weathered but otherwise looked new and believe battery is “new.” However the battery is new and four years old but charged fine. I’m guessing these batteries are leftover unsold batteries sold at a discount due to being out of warranty or close to it. So what you are buying could be a one shot deal with no warranty. The batteries may work just fine but know if you have a warranty issue, it won’t be backed up from most online Amazon sellers. A recognized Milwaukee vendor (ie Home Depot) usually recognize date of sale as start of warranty. Worth a gamble though as these 6.0 amh batteries are usually among the better high output batteries for reliability. ... show more
