OneMix 3 / 3S / 3 Pro Replacement Battery

Your OneMix 3, 3S or 3 Pro running on fumes? Here's the genuine OEM battery – not a cheap knock-off, but the exact part that was originally installed. Fair warning: these are old stock from 2020, so expect some reduction in capacity.

  • Compatible with OneMix 3, OneMix 3S, and OneMix 3 Pro – all three variants covered.
  • Genuine OEM part with a rated capacity of 8,600 mAh / 33.11 Wh as a Li-Polymer cell.
  • Not a third-party replacement – this is the same part used in the original build.
  • Old stock from 2020: actual capacity may be somewhat lower due to age.

Let's be honest: What you need to know

These batteries are from 2020 and have been in storage since then. Li-Polymer batteries lose capacity over time even when stored correctly – that's just physics, not a defect. You're getting a genuine OEM battery at a correspondingly low price, but you should expect the original rated capacity of 8,600 mAh to not be fully achievable anymore. For many use cases this is still perfectly fine – especially if your current battery no longer charges at all or drains very quickly.

Important Notice Regarding Installation

⚠️ Replacing the battery requires opening the device. This requires technical skill and the right tools. We accept no warranty or liability for any damage caused by improper installation. If in doubt, we recommend having the battery installed by a qualified technician. There are good video tutorials available online to walk you through opening the OneMix 3.

Who is this for?

  • Your OneMix battery is defective or no longer holds a charge.
  • You want to keep using your device a bit longer without spending a lot.
  • You have experience opening mini-laptops or know someone who does.
