Keeping power tools running strong is essential whether you’re wrenching on a car, building furniture in the garage, renovating your house, or working on the jobsite all day. Compact batteries can get you through smaller tasks, but when you need longer runtime and consistent muscle, a higher-capacity pack makes all the difference. That’s especially true with cordless systems that support dozens of tools, where swapping batteries less often helps keep the project moving. And with this battery pack deal we found at Walmart, you can power all your Milwaukee M12 cordless power tools for longer.
For a limited time, you can get your hands on the Milwaukee M12 RedLithium XC 3.0Ah Batteries for just $73 at Walmart, a 37% discount off the regular $116 price. These 12-volt batteries deliver twice the runtime and better overall performance than Milwaukee’s standard M12 compact units, giving your tools stronger and longer-lasting power. They work with every tool in the M12 lineup — from ratchets and impact drivers to reciprocating saws and drills — making this a great investment for anyone already rocking Milwaukee tools.
Each battery is designed for heavy use, offering fade-free power, fast recharging in as little as 30 minutes, and a rugged build built for demanding work environments. A built-in fuel gauge makes it easy to keep track of power levels on the fly, while their flat-bottom design allows M12 tools to stand upright with the battery installed, and these are heavy enough to prevent tipovers from bigger tools. Whether you rely on Milwaukee tools daily or just want to reduce downtime during bigger DIY projects, these XC 3.0Ah packs extend runtime and keep your tools juiced up.
“Very long lasting,” said one satisfied buyer who’s happy with the life these batteries come with. “[They] provide consistent power output until nearly discharged.”
Another customer compared them to the smaller units from Milwaukee, noting, “These are a very good upgrade to the M12 2.0Ah batteries.”
