At a Glance
Overview
The RYOBI PBP005 is a genuine ONE+ 18V 4.0Ah battery with a built-in LED fuel gauge — a step up in both capacity and convenience from RYOBI's base 1.5Ah/2.0Ah packs, priced at $54.99. It fits RYOBI's entire ONE+ 18V ecosystem, which is the platform's real selling point: one battery family across 300+ tools going back to 2011.
We haven't bench-tested this pack. This is a straightforward look at fit, the fuel gauge feature, and where 4.0Ah sits in RYOBI's lineup.

Who it's for
This pack is a solid upgrade for anyone already running ONE+ 18V tools who wants more runtime than a starter 1.5Ah pack provides, and who values being able to check remaining charge without pulling the battery off the tool. It's not the platform's highest-capacity option, but 4.0Ah is a meaningful step up for daily use.
Compatibility
Every ONE+ 18V battery from 2011 onward fits every ONE+ tool — that's RYOBI's headline compatibility promise, and this pack is no exception, from basic drivers up to HP High Performance tools. It will not fit RYOBI's 40V outdoor-power tools; ONE+ 18V and 40V are entirely separate platforms with no shared batteries or chargers.
The fuel gauge, and genuine vs. aftermarket
The LED fuel gauge is a real convenience — you can check remaining charge at a glance instead of guessing or waiting for the tool to bog down. As a genuine RYOBI pack, it also carries RYOBI's 3-year warranty. Aftermarket ONE+-compatible packs exist, often without a fuel gauge and always without RYOBI's warranty backing — worth weighing against the modest price difference on a pack this affordable already.
Buying notes
At $54.99, this sits above RYOBI's smaller 1.5Ah/2.0Ah packs but is still budget-friendly relative to pro-grade brands. Keep in mind ONE+ tools generally run lighter-duty than Milwaukee M18 or DeWalt 20V MAX gear, so the capacity math looks a little different across brands.
My Verdict
This genuine ONE+ 18V pack pairs real runtime with a built-in fuel gauge — a straightforward upgrade for anyone already in the RYOBI ONE+ ecosystem.
