Rubi CAS Li-Power 18V 5.2 Ah Battery — Long Runtime, Fewer Swaps

When you're mixing deep batches, running a vibrator across a big floor, or working a cordless tool hard all day, runtime is everything. This Rubi CAS Li-Power pack delivers it: 18V at a high 5.2 Ah for more time between charges and fewer interruptions to swap and wait. It's the pack you reach for when stopping to recharge costs you real momentum.

It rides the same CAS (Cordless Alliance System) platform, so you can standardize across 45+ brands and hundreds of tools on one battery system. Smart thermal management keeps it durable through repeated charge cycles and jobsite heat, and a built-in LED charge indicator keeps you informed. It's built for large-format work, deep mixing, cordless vibrating, and any tool that earns its keep by running long. For light overhead work, keep a 2.0 Ah pack on hand too.

Why Tile Pros Choose It

• Long runtime: High 5.2 Ah capacity means fewer swaps and recharges
• Cross-brand: CAS platform standardizes across 45+ brands
• Jobsite-tough: Smart thermal management for repeated cycles and heat
• Charge at a glance: Built-in LED charge indicator
• Built for heavy draw: Large-format work, deep mixing, cordless vibrating
• Keeps you working: Less downtime waiting on a charger

Pro tip: Put this high-capacity pack on your heavy-draw tools (mixers, vibrators) and keep a lighter pack for overhead work — you get runtime where it matters and less weight where it doesn't. Let a hot pack cool before recharging for the longest service life.
