Power tool batteries çan be tricky. A battery that's part of the same ecosystem as a power tool might technically fit and technically power that tool, but slotting a lightweight 2.0Ah battery into a reciprocating saw just isn't going to provide the power or longevity to make using it a satisfying experience. High-capacity, high-output batteries are worth it when you need your tools to get heavy-duty work done, and Walmart has a great deal on a pair of one of the best options on the market.
The Milwaukee M18 RedLithium High Output XC 6.0Ah Battery 2-Pack is on sale for $187 at Walmart, 37% off its normal $299 price tag. That's less than $100 per battery for a pair that represents a significant upgrade over the previous line of M18 batteries.

The most important thing to know about these batteries is that they are engineered to deliver 50% more power and run 50% cooler (which extends the lifespan of your tools) than standard M18 RedLithium XC batteries. They also perform better in subzero weather, even under heavy loads, and are still compatible with all 250+ M18 tools on the market. They're the best batteries for heavy-duty use in tough conditions by people, including serious DIYers and professionals, who need to get the most out of their tools and know what it looks like when they're not.

One shopper noted that "they are a little bulkier than the XC line, but on newer tools like saws, grinders, and impact wrenches they make a difference in terms of both power output and runtime."
Another satisfied customer added that "my regular Milwaukee batteries die out quickly in the cold but these seem to hold out really well." Others called them "amazing batteries" that "last longer" and "don't get as hot as my old batteries."
Deals We're Loving
Using the Milwaukee M18 RedLithium High Output XC 6.0Ah Battery 2-Pack means better-performing, longer lasting power tools. Their current $187 price tag is more than worth the benefits of these batteries, and if you use Milwaukee tools you should grab them before this deal runs out of juice.
