Ryobi PBP005 18V ONE+ 4Ah Battery — Up to 3x Runtime, LED Gauge, Lightweight

Power that keeps up with your workflow

The Ryobi PBP005 is built for the demands of modern cordless work. As part of the 18V ONE+ system, this 4Ah battery promises up to three times more runtime than older models, helping you stay productive longer between charges. The internal chemistry is designed to provide fade-free power, so you can optimize the full charge in varied weather conditions without worrying about sudden drops in performance.

A bright LED fuel gauge on the battery clearly indicates remaining runtime, so you can plan tool usage and recharging more efficiently. The result is a more predictable experience on site, in the workshop, or during outdoor tasks.

Designed for comfort and durability

The PBP005 uses a compact, lightweight frame intended to reduce user fatigue during long sessions. Anti-vibration technology adds durability and smoother operation, especially when tools are used for extended periods or in rough conditions. Quick-release latches make swapping batteries fast and secure, so you can move from one task to the next with minimal downtime.

Part of the 18V ONE+ ecosystem

With over 260 cordless tools sharing the same battery platform, this battery can power multiple devices from drills to saws, lights, and more. The kit includes one PBP005 18V ONE+ 4.0 Ah Lithium-ion Battery and an Operator’s Manual; chargers are sold separately.

Use cases and what to expect

• Overhead installations, cabinet work, and long-duration tasks become more manageable thanks to extended runtime.
• Outdoor projects or retrofit jobs benefit from fade-free performance and clear runtime visibility.

• Compact design reduces fatigue, enabling more precise control in tight spaces.
• Secure quick-release latches simplify battery changes without tools.

Note: Benefits described here are based on product features and system design; actual results depend on tool, workload, and application.
