Find your replacement battery.

Identify your tool brand and platform voltage (printed on the tool or its original battery), then find that brand below. If your current OEM battery model is in the "Replaces" list — for example DeWalt DCB205 or Makita BL1860B — a CEENR pack of the same brand is a direct drop-in fit. Pick the capacity you want (5.0, 6.0 or 8.0 Ah); they share the same mount, so almost every tool on that platform takes any capacity listed for your brand. The few tools with a covered battery bay or a pack-size limit are marked on each brand's verified tool list.

Yes. A higher-capacity battery on the same platform delivers the same voltage — it just runs longer between charges, and on high-draw tools it sags less under load. Almost any tool that accepts your brand's battery takes a 5.0, 6.0 or 8.0 Ah CEENR pack of that brand; the few with a covered battery bay or a pack-size limit are marked on the verified tool lists. Higher-capacity packs are slightly taller or heavier because they hold more or larger cells, but the mount and latch are identical.

Yes. "Brushless" (DeWalt XR/ATOMIC, Milwaukee FUEL, Makita, Ryobi HP, etc.) describes the tool's motor, not a battery requirement. Any quality battery on the right platform runs brushless tools normally. For the highest-draw brushless tools — impact wrenches, circular saws, rotary hammers — use a 6.0 or 8.0 Ah pack rather than a small 1.5-2.0 Ah pack to keep voltage steady and reduce heat.

Yes — that is what the CEENR PDnation universal battery does. With a $15.99 per-brand Brand Mount, one PDnation pack runs 1,600+ tools across 10 brands (DeWalt, Milwaukee, Makita, Bosch, Ryobi, and more), and it doubles as a 100W USB-C power bank. Sister brands do not share batteries: Black+Decker 20V MAX, Craftsman V20 and Porter-Cable 20V MAX are separate Stanley Black & Decker platforms, each listing only its own packs.

Not automatically. The US Magnuson-Moss Warranty Act (15 USC § 2302(c)) generally bars a tool maker from making warranty coverage conditional on its own branded batteries, but the maker can decline a repair for damage a third-party battery caused, and some tool warranties exclude damage from incompatible parts or accessories. The CEENR battery itself carries its own 3-year warranty, separate from the tool warranty.
