Product description
What this product is
This item consists of two 18V lithium-ion replacement batteries, each with a capacity of 5500 mAh (5.5 Ah) and an integrated power indicator. They are designed to replace Ryobi 18V ONE+ batteries and are compatible with Ryobi cordless tools and chargers that use the P102, P103, P104, P105, P106, P107, P108 or P109 formats.
How it works in practice
The batteries are built to align with the voltage needs of Ryobi 18V ONE+ tools, offering a higher capacity for longer runtime in comparison with some standard options. The presence of an integrated microchip helps manage charge and discharge to reduce the risk of deep discharge, overload, and short circuit, contributing to safer operation and potentially longer life.
What to know before you buy
If you already own Ryobi tools within the 18V ONE+ ecosystem, these replacements should slot into the existing tool and charger setup, with fast charging support available when used with Ryobi P117 or P118 chargers.
The best and the limits
The two-pack format is convenient for households with multiple tools or a spare battery approach. On the downside, the claim to “improved capacity” rests on 5500 mAh cells, real-world run time will depend on tool type, workload, and usage conditions. The note about allowing a battery to cool before charging after a full discharge is worth following to maximise charge acceptance.
Who it’s for
Ideal for DIYers and light professionals already invested in Ryobi 18V ONE+ gear who want more minutes between charges or a ready spare without relying on third-party alternatives.
Who it isn’t for
If your aim is the absolute lightest possible battery or you require the latest proprietary features from newer Ryobi packs, this alternative may not align with those expectations.
When it makes sense to buy
Consider this two-pack if you want dependable replacements that cover typical home workshop tasks, keep tools working longer between charges, and you don’t need to chase the very latest battery tech.
What to check before purchasing
- Confirm compatibility with your Ryobi 18V ONE+ model (P102–P109 family) and with your charger (P117 or P118 for fast charging).
- Be aware that charging after a full discharge should be approached with a brief cooldown period for optimal charging.
- Verify the inclusion of two batteries and any accompanying user manual.
Practical use case
You’re mid-project, your drill or saw starts to slow down, swapping in one of these 5.5 Ah packs can help sustain performance for longer sessions without frequent recharging. The built-in indicator lets you gauge remaining power on the fly.
Quick comparison in practice
For those weighing options within the Ryobi ecosystem, these packs offer a straightforward replacement route with current-capacity performance. If you’re seeking the newest tech features or the lightest possible pack, you might explore other options within or beyond the Ryobi line, but for many standard tasks these packs strike a sensible balance between runtime and cost.

Final decision
