The built-in LED indicator lets you gauge remaining run time at a glance, reducing downtime on the job.

These batteries are designed to be a practical alternative to OEM packs, offering strong compatibility with the Ryobi One+ ecosystem and the original chargers (such as P117 and P118).

Real-world use and care tips

In daily use, you might notice the LED panel signaling when a top-up is due, helping you schedule breaks and stay productive on-site. For best results, avoid charging immediately after a full discharge; allow the battery to cool before reconnecting to charge. When not in use, store at moderate temperatures to help preserve longevity.

To maximize compatibility and performance, pair these packs with the Ryobi 18V ONE+ charger designed for PBP-series packs. This pairing supports a smooth workflow across a range of tools without needing to mix and match incompatible devices.
