About CEENR
CEENR — universal power for 1,600+ tools across 10 brands. Built on premium high-drain cells. Founded by pros, for pros.
Power that belongs to you — not your tool brand.
Vision
A world where a single battery powers everything cordless — across every brand, and outlives the devices it runs. CEENR® exists to become the independent power platform that frees people from brand lock-in, one cordless category at a time.
Mission
We replace a drawer full of brand-locked, overpriced, throwaway batteries with one reliable platform: PDnation. Today it powers 1,600+ power tools across 10 brands. Vacuums are next on our roadmap — and the list keeps growing.
Brand story
Every cordless brand sells you the tool once — and the battery forever. Proprietary shapes. Locked ecosystems. Prices that never fall. Packs that quietly die just past warranty. We thought that was backwards.
A typical tradesperson owns tools from four or five brands — DeWalt for impact drivers, Milwaukee for saws, Makita for grinders, Bosch for the rotary hammer — each with its own battery, its own charger, and its own pile of dead packs in the garage. So we built CEENR to tear down the walls between brands. PDnation is one universal pack plus a snap-on mount: the same battery crosses every major ecosystem, charges over standard USB-C, and doubles as a 100W power bank — so power is never trapped inside one tool. Behind the simplicity is real engineering: high-drain 21700 cells, USB-C Power Delivery, verified tool compatibility, and a 3-year warranty.
We started with power tools. Next on our roadmap: PDnation Vac brings the same platform to vacuums — same belief, new category. We're rebellious about brand walls, and obsessive about reliability.

Why we use premium high-drain cells in PDnation
Most cheap aftermarket batteries use generic, low-grade cells. We build PDnation on premium high-drain 21700-format cells, built for sustained high-current draw. Cell format alone does not determine runtime, operating temperature or cycle life; those depend on the exact cell and complete battery design.
Across the replacement line we match the right high-drain cell to each use case — tuned for the best discharge curve at 5.0Ah, the best cycle life at 6.0Ah, and the best energy density at 8.0Ah.
