Upgraded 3600mAh Replacement for Ryobi 18V Battery (2-Pack)

In this review the Upgraded 3600mAh Replacement for Ryobi 18V Battery (2-Pack) with Charger Combo is assessed for tradespeople and DIYers who need reliable runtime for Ryobi 18V ONE+ tools. The bottom line: it is a practical, budget-friendly replacement that doubles typical P102 runtime thanks to high-capacity lithium-ion cells, and the included P117-style charger covers 9.6V through 18V battery types so charging is convenient on mixed battery benches. The review focuses on fit, runtime, charging behavior and build quality to help decide if it is the right swap for OEM batteries.

Key Features

• High capacity: The 3600mAh (3.6Ah) cells provide extended runtime compared with many standard P102 replacements, useful for longer cutting or drilling sessions.
• Wide charger compatibility: The included charger accepts 100V-240V input and outputs 9.6V-18V, allowing charging of NiCad, NiMh and lithium-ion Ryobi-compatible packs on one unit.
• Intelligent protection: Built-in adaptive chip provides overcharge, overcurrent, overvoltage and overtemperature protection for safer charging and use on job sites.
• Durable shell: The PC+ABS housing improves toughness and impact resistance so the packs tolerate daily handling and occasional knocks.
• Power indicators: Four LED indicators show remaining battery and charging status, helping plan swaps without guessing capacity.

Who It's For

This kit suits homeowners, hobbyists and professional users who rely on Ryobi 18V ONE+ tools and want a cost-effective way to double available runtime without buying OEM packs. The pair of 3.6Ah batteries is convenient for medium-duty tasks like drilling, driving and light demolition where swapping between two packs keeps workflow steady.

Users who need extreme runtime for all-day heavy construction use or who demand manufacturer warranty support from an OEM pack should consider higher-capacity official options or factory replacements. Also, those who require instant-charge diagnostics from a branded charger interface may prefer a manufacturer charger.

Pros & Cons

Pros

• Good value: two 3.6Ah packs cost much less than many OEM equivalents while fitting Ryobi 18V ONE+ tools perfectly.
• Longer runtime: the higher-capacity cells often run noticeably longer than other P102 replacements in similar tasks.
• Safe charging: the adaptive protection chip and multi-chemistry charger make charging straightforward and reduces risk of misuse.

Cons

• Mixed runtime reports: some users report sessions under 30 minutes for high-draw tools, so performance can vary by tool and task.
• The charger is a universal solution but lacks advanced OEM charging diagnostics some users expect.

Specifications

Our Verdict

The 3600mAh replacement 2-pack with charger is a sensible, budget-minded choice for most Ryobi 18V ONE+ users who want more runtime and flexible charging without paying OEM premiums. It combines higher-capacity cells, safety electronics and a universal charger to deliver good value, though extreme heavy users may still want higher-capacity branded packs for full-day work.
