Ultraxxis 18V Replacement Batteries, 6.0Ah Lithium-Ion, 2-Pack
Product description
For a cordless drill or other Ryobi ONE+ tool that needs a spare battery, this Ultraxxis two-pack offers a pair of rechargeable 18V lithium-ion replacements. Each is listed at 6.0Ah, and an LED indicator is designed to show remaining power so you can keep an eye on charge while working.
The pack is intended for compatible Ryobi 18V ONE+ tools and chargers, with several P-series battery references named in the product details. It’s a replacement-battery purchase, not a new tool kit, so the main decision is whether the stated compatibility and two-battery format suit the tools you already own.
Who it’s for
This set makes sense for someone with compatible Ryobi 18V equipment who wants two rechargeable batteries on hand rather than buying a single replacement. For a home project, one battery can be in use while the other is available as a spare, that can be more convenient than stopping to wait for a recharge, although actual runtime and charging behavior can vary.
The listed compatibility includes P102, P103, P104, P105, P107, P108, and P109 batteries. The product title also names P122, while the detailed compatibility list does not, so match your tool and battery reference against the information for your exact setup before choosing. It’s a great fit if you need a two-pack for tools in the stated 18V system. If you only need one replacement, a single battery may be a simpler purchase.
Technical overview
- Type: Rechargeable lithium-ion replacement batteries
- Voltage: 18V
- Capacity: 6.0Ah per battery, as listed
- Quantity: 2 batteries
- Compatibility: Selected Ryobi 18V ONE+ cordless tools and chargers
- Indicator: LED charge indicator
- What’s included: Two batteries and a user manual
The LED is intended to make remaining power easier to check before the battery runs low. The product details also describe built-in protection against overcharging, over-discharging, overvoltage, overcurrent, and overheating. These are listed features, not a guarantee of a particular runtime or charging result.
Why it’s worth it
The useful distinction here is the two-battery format: it suits buyers who prefer to keep a spare ready, while someone replacing a battery for occasional, short jobs may have less need for a pair. The stated 6.0Ah capacity and LED indicator give you specific details to compare with a basic replacement, but they don’t establish how long a charge will last in every tool or task.
Buyer feedback is positive about fit and use as a replacement in Ryobi tools, but reports on battery life and charging are mixed. Some buyers describe long use between charges, while others report short runtime or charging problems. That variation is worth weighing if consistent performance matters more than having two batteries available. Depending on how you use it, the tool and workload may also affect the experience.
Buying verdict
Consider this Ultraxxis pack if your priority is two 18V lithium-ion replacements with a stated 6.0Ah capacity, an LED indicator, and compatibility with the listed Ryobi ONE+ references. Before buying, make sure your battery or tool reference appears in the compatibility details, especially if you are relying on P122, which is named in the title but not in the longer list. It may not suit you if you need a single battery or want dependable runtime and charging performance established for your particular tool, the available buyer feedback is mixed on both.
