Ryobi’s ONE+ platform is the most popular consumer battery system in the world, with over 300 tools sharing the same 18V battery. But with nearly a dozen different battery options — from tiny 1.5Ah compacts to massive 9.0Ah HP packs — choosing the right one can be overwhelming.
This guide covers every current Ryobi ONE+ battery, explains the differences between standard and HP (High Performance) packs, and recommends the best battery for each type of use.
Ryobi ONE+ Battery Lineup
| Model | Capacity | Type | Weight | Best For |
|---|---|---|---|---|
| P189 | 1.5Ah | Standard | 0.37 kg | Light tasks, backup battery |
| P190 | 2.0Ah | Standard | 0.42 kg | General light-to-medium use |
| P107 | 3.0Ah (older) | Standard | 0.54 kg | Budget all-rounder |
| P108 | 4.0Ah | Standard | 0.62 kg | Most popular general-purpose choice |
| P197 | 4.0Ah HP | High Performance | 0.66 kg | Power tools needing extra punch |
| PBP005 | 4.0Ah HP | High Performance | 0.65 kg | Updated HP compact |
| PBP007 | 6.0Ah HP | High Performance | 0.88 kg | Extended heavy-duty use |
| PBP010 | 9.0Ah HP | High Performance | 1.13 kg | Maximum runtime for demanding tools |
Standard vs HP (High Performance) Batteries
This is the most important distinction in the Ryobi ONE+ lineup. Both standard and HP batteries are 18V and physically fit every ONE+ tool, but they perform very differently.
Standard ONE+ Batteries
Standard batteries use conventional lithium-ion cells and deliver reliable performance for light-to-medium tasks. They’re perfectly adequate for drills, drivers, trimmers, lights, and fans. They’re also significantly cheaper than HP packs.
HP (High Performance) Batteries
HP batteries use higher-grade cells that can deliver more current with less voltage sag. This matters for power-hungry tools like circular saws, reciprocating saws, and angle grinders. HP packs also perform better in cold weather and maintain higher power output as the charge depletes.
Do you need HP batteries? If you mostly use drills, drivers, and lighter tools, standard batteries are fine. If you use saws, grinders, or any tool that bogs down under load with standard packs, HP batteries make a noticeable difference.
Best Ryobi Battery for Each Use Case
Best for Drilling and Driving
P108 (4.0Ah Standard) or P190 (2.0Ah Standard)
Drills and impact drivers don’t draw massive current, so standard batteries work perfectly. The 4.0Ah P108 gives great runtime, while the lighter 2.0Ah P190 reduces fatigue for overhead work and extended driving sessions.
Best for Saws and Grinders
PBP007 (6.0Ah HP)
High-draw tools benefit significantly from HP batteries. The 6.0Ah HP delivers the sustained current these tools need without bogging down, and the larger capacity means fewer interruptions during long cuts.
Best for Garden and Outdoor Tools
PBP007 (6.0Ah HP) or PBP010 (9.0Ah HP)
Lawn mowers, leaf blowers, and hedge trimmers run continuously and drain batteries quickly. Go for the highest capacity you can afford. The 9.0Ah HP is heavy but delivers genuine extended runtime for mowing larger lawns.
Best Budget Option
P108 (4.0Ah Standard)
The best balance of price, capacity, and weight. It handles the vast majority of ONE+ tools competently and is frequently available in two-packs at a significant discount.
Best Lightweight Option
P189 (1.5Ah Standard) or P190 (2.0Ah Standard)
For situations where every gram matters — working overhead, using a multitool in tight spaces, or keeping a flashlight light. These compact packs are best as supplements to larger batteries rather than primary power sources.
Backwards Compatibility
One of Ryobi ONE+’s biggest selling points is backwards compatibility. Every ONE+ battery made since the platform’s launch works in every ONE+ tool, past and present. A brand new 9.0Ah HP battery works in a 15-year-old ONE+ drill, and a decade-old battery still fits the latest tools.
However, older standard batteries won’t deliver the enhanced performance that newer HP tools are designed to leverage. They’ll work, but you won’t get the full power output.
Charging Tips
- Use the right charger — The standard P118B charger works for all batteries but charges slowly. The dual-chemistry IntelliPort P135 charges faster and handles both lithium and NiCd packs.
- The 6-port supercharger (P136) is worth it if you have a large ONE+ collection — it charges six batteries simultaneously and prioritises the most depleted pack.
- Don’t store batteries fully charged or fully depleted — 40-60% charge is ideal for long-term storage.
- Avoid leaving batteries in extreme temperatures — especially a hot car boot or an unheated garage in winter.
How Many Batteries Do You Need?
A good starting point:
- Casual DIY: 2 batteries (one in use, one on the charger)
- Regular DIY: 3-4 batteries, at least one HP if you use saws
- Serious workshop: 5+ batteries in a mix of capacities — smaller packs for light tools, larger HP packs for heavy-duty work
Frequently Asked Questions
Do all Ryobi ONE+ batteries fit all ONE+ tools?
Yes. Every Ryobi ONE+ battery — standard or HP, any capacity — physically fits and works in every ONE+ tool, regardless of when either was manufactured. This backwards and forwards compatibility is one of the platform’s strongest features.
Is a Ryobi HP battery worth the extra cost?
For drills, drivers, and light-duty tools, standard batteries perform well and HP isn’t necessary. For saws, grinders, mowers, and other high-draw tools, HP batteries make a noticeable improvement in power delivery and runtime. If your budget allows, having at least one HP battery for your most demanding tools is worthwhile.
What is the best Ryobi ONE+ battery for a lawn mower?
The PBP010 (9.0Ah HP) provides the longest runtime for mowing. For smaller lawns, the PBP007 (6.0Ah HP) offers a good balance of weight and runtime. Avoid using standard (non-HP) batteries in mowers, as they’ll struggle under the sustained high current draw.
Can I use old Ryobi NiCd batteries in new ONE+ tools?
Older Ryobi ONE+ NiCd batteries physically fit newer tools, but performance will be poor compared to lithium-ion packs. NiCd batteries are heavier, hold less charge, suffer from memory effect, and deliver less power. We strongly recommend upgrading to lithium-ion batteries.

Which Ryobi ONE+ battery is best for most users?
The Ryobi P108 4.0Ah battery offers the best balance of runtime, weight, and price for most DIY users. It provides enough power for drills, impact drivers, and light saws without being too heavy.
Is a bigger Ryobi battery always better?
Not necessarily. Larger capacity batteries (6Ah+) add significant weight that can cause fatigue during overhead work or extended use. For lighter tasks like drilling and driving, a 2-4Ah battery is often more practical.
Do all Ryobi ONE+ batteries fit all Ryobi ONE+ tools?
Yes. All Ryobi ONE+ 18V batteries are cross-compatible with all 300+ tools in the ONE+ range, regardless of Ah capacity. A compact 1.5Ah battery fits the same tools as a high-capacity 6Ah battery.
