The Ryobi P107 is a 1.5Ah compact battery for the Ryobi ONE+ 18V platform. It’s the entry-level battery often included with budget tool kits — light, affordable, and perfectly adequate for occasional DIY use. Here’s what you need to know about replacing it.
P107 Specifications
Voltage: 18V
Capacity: 1.5Ah (27Wh)
Chemistry: Lithium-ion
Platform: Ryobi ONE+
Fuel gauge: Yes — onboard LED indicator
Weight: Approximately 0.33 kg
What Tools Does the P107 Fit?
The P107 fits all 300+ tools in the Ryobi ONE+ 18V range. Its ultralight weight makes it handy for quick tasks — driving a few screws, inflating tyres, or powering a work light. For heavier tools like circular saws or rotary hammers, you’ll get very short runtime from a 1.5Ah battery, so an upgrade is worth considering.
Replacement Options
Direct replacement (same spec): Ryobi 1.5Ah ONE+ batteries are available individually, though at this price point you often get better value buying a twin pack of 2.0Ah batteries instead.
Upgrade options (recommended): Since the P107 is the smallest battery in the ONE+ range, almost any replacement is an upgrade:
- P197 (2.0Ah) — 33% more runtime for minimal extra weight and cost. The best like-for-like upgrade
- P108 (4.0Ah) — Nearly triple the runtime. Ideal if you found the P107 running out too quickly on most tasks
- PBP005 (3.0Ah HP) — Compact size with HIGH PERFORMANCE cells for better output in ONE+ HP tools
Every Ryobi ONE+ battery is cross-compatible, so any of these drop straight into your existing tools.

Tips for Getting the Most from Your Replacement
Small-capacity batteries like the P107 have less thermal mass, so they heat up faster under load. Avoid using them for sustained high-drain tasks like circular saws — they’ll last longer if you stick to lighter tools. For battery care advice, see our Battery Care & Storage Guide.

Frequently Asked Questions
What tools come with the Ryobi P107 battery?
The P107 (1.5Ah) is commonly included as the stock battery in Ryobi ONE+ starter kits and combo tool sets. It is a compact, lightweight battery designed for basic tasks. Many users replace it with a higher-capacity battery once they begin using more demanding tools.
Can I use the P107 in a Ryobi lawn mower?
Technically yes — any ONE+ battery fits any ONE+ tool. However, the P107’s 1.5Ah capacity will only power a lawn mower for 5-10 minutes, which is impractical. Ryobi recommends 4.0Ah or higher for outdoor power tools. For mowing, the 6.0Ah PBP007 or 9.0Ah PBP012 is a much better choice.
Is a replacement P107 worth it or should I upgrade?
Unless you specifically need the ultra-compact form factor for tight spaces, upgrading is the better investment. A 2.0Ah or 4.0Ah battery costs only slightly more than a P107 replacement and provides significantly better performance and runtime across all your ONE+ tools.

Signs Your P107 Battery Needs Replacing
Lithium-ion batteries degrade naturally over time. Here are the key signs that your Ryobi P107 battery needs replacing:
- Rapid discharge: The battery drains noticeably faster than when it was new, even after a full charge. If a battery that once lasted an hour now dies in 20 minutes, capacity has degraded significantly.
- Charges but dies quickly under load: The battery appears to charge fully but shuts off within minutes when powering demanding tools. This indicates internal cell failure where the battery can no longer deliver sufficient current.
- Excessive heat during use or charging: While some warmth is normal, a battery that becomes uncomfortably hot during operation or on the charger has damaged cells. Excessive heat is both a symptom and a cause of further degradation.
- Physical swelling or damage: Any visible bulging, cracking, or deformation of the battery casing means the cells inside have failed. Stop using a swollen battery immediately and dispose of it safely at a recycling point.
- Charger error indicators: If your Ryobi charger flashes red or shows error lights rather than charging normally, it has detected a fault in the battery. Most Ryobi chargers include diagnostic features that identify damaged batteries.
- Age beyond 3-5 years: Even well-maintained lithium-ion batteries lose 20-30% of their original capacity after 3-5 years of regular use. If your battery is approaching this age and performance has declined, replacement is worthwhile.
OEM vs Third-Party Replacement Batteries
When replacing your Ryobi P107, you have two main options: genuine Ryobi batteries or third-party compatible alternatives. Both will physically fit and power your ONE+ tools, but there are meaningful differences worth considering.
| Factor | Genuine Ryobi | Third-Party Compatible |
|---|---|---|
| Typical Price | £30-55 | £15-30 |
| Cell Quality | Tested to Ryobi standards | Varies by manufacturer |
| Warranty | 3-year Ryobi warranty | 6-12 months typically |
| Safety Certifications | Full Ryobi standards, CE marked | CE marked, meets EN standards |
| Expected Lifespan | 800-1,000 charge cycles | 400-700 charge cycles |
| Performance Consistency | Optimised for all ONE+ tools | Compatible, slight variation possible |
Choose genuine Ryobi batteries if you want the security of a full manufacturer warranty and guaranteed compatibility across all 300+ ONE+ tools. Ryobi batteries are tested specifically for the ONE+ ecosystem and offer consistent, predictable performance.
Third-party batteries make sense for budget-conscious users who want to expand their battery collection affordably. Ryobi ONE+ is particularly well-served by the aftermarket because of its massive user base. Reputable third-party manufacturers engineer their batteries to strict compatibility standards, and many users report excellent results at a fraction of the OEM price.
How to Get the Most from Your Replacement Battery
Follow these care tips to maximise the lifespan and performance of your new Ryobi P107 replacement battery:
- Complete the initial charge: Fully charge your new battery before first use. This calibrates the battery management system and ensures accurate charge level readings from the start.
- Store at 40-60% charge: For long-term storage, keep your battery at roughly half charge. Storing a battery fully charged or completely depleted accelerates capacity fade. Check stored batteries every 2-3 months.
- Avoid temperature extremes: Keep your battery between 5°C and 40°C during use and storage. Never leave batteries in a hot vehicle or exposed to direct sunlight. Cold weather temporarily reduces output but does not cause permanent damage.
- Remove from charger promptly: Once fully charged, disconnect your battery. Leaving it on the charger continuously causes unnecessary stress on the cells, even with Ryobi smart chargers.
- Use compatible Ryobi chargers: Always use Ryobi ONE+ chargers (P118B, P117, or the dual chemistry IntelliPort charger). These include essential safety features like temperature monitoring and overcharge protection that generic chargers may lack.
