Our Terms of Sale explains that the warranty does not cover used batteries, although we guarantee that they will last for at least an hour. We will replace batteries that do not meet these criteria if reported within one week of receipt and the supplied battery is returned. Batteries are considered consumables - as they are expected to degrade over time.

To verify lifespan of battery please run a quick battery report:

  1. Right-click the Start Button and choose CMD Command Prompt or Windows PowerShell, then type this command:

    powercfg /batteryreport

  2. Next, head to your user folder and look for battery report.html at this location:  

    C:\Users\USERNAME\battery report.html
