Rubi CAS Li-Power 18V 2.0 Ah Battery — Light Power, Shared Across Brands

The best thing about this battery is what it fits. It runs on the CAS (Cordless Alliance System) platform — a cross-brand standard shared across dozens of manufacturers and hundreds of tools — so one battery system powers your Rubi cordless gear and a whole lot more, instead of locking you into a single brand's ecosystem.

At 18V and 2.0 Ah, it's compact and lightweight, which makes it ideal for overhead and wall work and quick tool swaps where a big pack just weighs you down. An integrated LED status light shows remaining charge at a glance, so you're not caught guessing mid-cut. It powers Rubi CAS cordless mixers, tile vibrators like the Quake, lights like the Lumeo, and more. Need longer runtime? Step up to the 5.2 Ah pack.

Pro tip: Keep this lighter 2.0 Ah pack for the tools you hold up high and a 5.2 Ah on the heavy-draw tools — matching pack size to the job saves weight where you want it and runtime where you need it. Store batteries out of the cold for the best performance and life.
