  • Charge it!
OE charger for battery. All good.
Reviewed in the United States on May 6, 2025 by My Diesel Genny

  • Redlithium Really Good
I like the compact design of these batteries and the compact Milwaukee tools they fit and the long life these batteries give. I have the M12 garden pesticide sprayer, right angle drill, and 3/8" ratchet. I am pretty invested in another brand of 18 volt cordless tools but for ultra compact lightweight cordless tools I am really liking the Milwaukee M12 lineup. ... show more

  • The Real Deal!
OEM batteries in manufacturer's packaging. Bulk wrap OEM charger. Exactly as advertised. This smaller battery doesn't pack a big punch but is great for Milwaukee's cold weather gear. Compact, lightweight and quick to charge. I love not having to take the battery connector/charger out of my coat. When I'm done wearing for the day, it's easy to pop the used battery out of the pocket, slap it into the charging station and put a fresh battery in the jacket. Ready to go! ... show more
