Ryobi ONE+ 18V 4.0 Ah Lithium-Ion Battery - Longer Runtime

In this review the Ryobi PBP005 ONE+ 18V 4.0 Ah Lithium-Ion Battery is evaluated for homeowners and tradespeople who already use the RYOBI 18V ONE+ system and need a compact, reliable spare or replacement. The bottom line: this battery delivers noticeably longer runtime and useful on-battery diagnostics, making it a practical upgrade for those wanting fewer mid-job swaps. The review focuses on real-world usability, runtime, weight, and fit across over 260 compatible ONE+ tools so readers can decide if it fits their workflow.

Key Features

• Up to 3X More Runtime: Provides significantly longer run times than the previous model so users can finish more tasks between charges.
• High Visibility LED fuel gauge: Lets you check remaining runtime at a glance so you can plan jobs and swaps without guesswork.
• Compact and lightweight design: Reduces user fatigue during extended use and makes the battery easier to carry between jobs.
• Fade-free power: Maintains consistent output throughout the charge so tools run reliably until the battery is depleted.
• Quick-release latches: Allow fast installation and removal, speeding up tool changes on busy job sites.
• Robust construction and anti-vibration technology: Improves durability and helps the battery withstand regular jobsite use.

Who It's For

This battery is a strong fit for DIY homeowners, landscapers, and contractors who already own RYOBI 18V ONE+ tools and want a compact pack with longer runtime. It is particularly useful for people who value on-battery information and want to minimize interruptions during sanding, trimming, or fastening jobs.

Users who need the absolute fastest charging system or who require very large-capacity packs for heavy industrial use should consider higher-capacity or fast-charge options. New buyers should confirm compatibility with their specific ONE+ tool models before purchasing.

Pros & Cons
