FAQ

Q: How is my shipping cost calculated?

Free Standard Shippingapplies to all orders over$30. If your order is below this amount, simply enter your zip code at checkout for an instant, real-time shipping estimate.





Q: Will these batteries work with my current tools?

Yes, within the same brand platform.While batteries aren't interchangeable between different brands (e.g., a DeWalt battery won't fit a Makita tool), our replacement batteries are engineered to100% match the original OEM connector and voltageof the specific brand they are designed for


Q: Understanding Specs: What do V and Ah mean?
  • Voltage (V): Think of this as the engine's power. Always match the voltage of your tool (e.g., 18V battery for an 18V tool).
  • Amp-Hours (Ah): Think of this as the size of your fuel tank. A higher Ah (e.g., 5.0Ah vs 2.0Ah) means a longer runtime per charge—it won't hurt your tool, it just lets you work longer.
