In-Store Exclusive

This one's worth the trip to the store.

Brands like Weber, Milwaukee, Yeti, and DeWalt restrict where their products can be sold online — and for good reason. In-store buyers get authentic products, full manufacturer warranty, and access to pricing that simply isn't allowed to be advertised on the web.

  • Authorized dealer network · Full manufacturer warranty & support
  • Guaranteed authentic · No counterfeits, no gray-market resellers
  • The brands set these standards · Be wary of sellers who don't follow them

About Product Overview

Job sites don't slow down for a dead battery, and this M18 RedLithium 5.0Ah pack from Milwaukee is built to keep pace with heavy, continuous use. It's the oil-resistant version, which matters if your tools spend the day around lubricants, cutting fluid, or general shop grime — the housing is designed to hold up where a standard pack might degrade. At 5 amp hours, it delivers extended runtime for demanding applications like drilling, sawing, and grinding without constantly cycling batteries.

It slots into the M18 system, so it works across Milwaukee's M18 lineup of drills, saws, and other cordless tools. RedLithium chemistry is engineered for more work per charge and a longer service life than standard lithium-ion packs, which pays off on tools that pull hard current. Charge time comes in at 60 minutes, so a spent pack gets back into rotation fast rather than sitting on the shelf. It ships one battery per clamshell package.

  • Battery type: Lithium-Ion, RedLithium sub-brand

  • System: M18 (compatible with M18 tools)
  • Oil-resistant housing for tougher job site conditions
  • Charge time: approximately 60 minutes

Every order helps keep your local hardware store on the corner.

Why we built NHG
You might find it for less locally. Independent retailers often offer competitive pricing — some products are even cheaper in-store than online.
Real expert advice — not search results. Independent hardware staff know their inventory and the local conditions you're working in.
Keep the neighborhood working. Every dollar spent at an independent retailer returns roughly 3x more to your local economy than at a national chain.

Ask our counter. Or theirs.

Most hardware stores can do more than you think. If we can't help you, the folks down the street probably can — just ask at the counter.

Their Counter
Try local first · we'll wait

The stores we send you to are local and independently run — often for generations, the kind of place where someone behind the counter knows the regulars. We don't own them. We just think they deserve the foot traffic. They can put most of what we sell on their next truck. Ask there before you check out here.

About our directory. National Hardware Group is an independent retailer and directory. The local stores we list and link to are separately owned and operated — we have no ownership stake in any of them, and most pay us nothing to be included. That includes plenty of stores flying a familiar banner that people don't realize are locally owned and run, not operated by a corporation. Store owners can choose to upgrade their listing for an enhanced presence or pickup features, but the base directory is free, and inclusion is never a paid endorsement.
