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

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.

About Product Overview

Meet UltraLast NiMH AAA 3.6 V 800 mAh Cordless Phone Battery, Model BATT-446 — a reliable, rechargeable replacement crafted to restore everyday reliability to your Uniden cordless phone. This compact AAA cell packs a solid 800 mAh capacity at 3.6 volts, delivering steady power when you need it most and reducing the anxiety of mid-call dropouts.

What makes this battery stand out

  • Optimal compatibility: specifically designed for Uniden cordless phones, ensuring a snug fit and dependable performance in compatible handsets.
  • Balanced capacity: 800 mAh provides longer talk-time between charges compared to standard entry-level cells, helping you stay connected without frequent replacements.
  • NiMH chemistry: rechargeable NiMH technology offers solid cycle life with reliable power delivery and straightforward recharging—no memory effect to worry about.
  • AAA size, practical design: compact form factor fits slim handset compartments while delivering robust voltage at 3.6V.
  • One-piece package: comes as a single battery in carded packaging, ready for quick replacement and easy storage.

Who should consider UltraLast BATT-446?

  • Home users keeping a Uniden cordless phone system running smoothly with a fresh, dependable power source.
  • Anyone seeking a straightforward replacement to extend the life of an aging handset without upgrading the whole system.
  • People who value a compact, easy-to-store backup battery that reliably powers phone calls, not just standby time.

Practical tips to get the most from your battery

  • Use a compatible rechargeable NiMH charger and avoid leaving the battery in extreme heat or direct sunlight to maximize cycle life.
  • Charge when the pack is depleted rather than leaving it fully discharged for extended periods to preserve capacity.
  • Handle with care—avoid punctures or exposure to water, and store in a cool, dry place when not in use.
  • If you notice shorter talk-time after replacement, ensure the battery is seated correctly in the handset and that the charger is functioning properly.

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 co-op 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.
