No worries! 🙌 It won’t affect charging or operation—just means your device might run a bit longer or shorter between charges. Still 100% compatible. Still 100% awesome. 💪✨

Ensure the original battery model number is mentioned in our product description and verify that your device model number is also listed in the description.
