Is your Bosch 18V PSR 18 drill losing power too quickly? A high-quality replacement battery can bring it back to life – often with longer runtime and lower cost than the original Bosch battery. In this guide, we’ll show you which models are compatible, what capacities we offer, and why our replacement batteries are the smart choice.
Our replacement batteries work with the following Bosch 18V models and part numbers. If your tool is on this list, our battery will fit.
Also compatible with most other Bosch 18V power tools using the same slide-style interface.
⚠️ Not compatible with: Bosch 14.4V systems, Bosch Professional GBA series (unless confirmed), or older Ni-Cd models.
Original Bosch batteries are reliable but expensive – often £50–70 or more. Our replacement batteries give you the same or better performance at a much lower price. Plus, you can choose the capacity that fits your usage.
| Battery | Capacity | Run Time (Typical) | Price vs OEM | Best For |
|---|---|---|---|---|
| 🔵 Bosch Original | ~2100mAh | ~20–30 min | Very expensive (£50–70+) | Strict warranty only |
| ⭐ Our Replacement | 1200mAh / 1500mAh / 3000mAh / 3500mAh | ~25 to ~60 minutes | Much cheaper – best value | Light DIY to heavy use – pick your capacity |
Note: Voltage remains 18V – higher capacity only means longer runtime, no risk to your tool.
