Compatibility & Models

1. Is this battery compatible with my MacBook 12″?
Yes, this A1527 / A1705 battery is specifically designed for the MacBook Retina 12″ models from 2015 to 2017. It is a direct replacement for the original battery in these models. Check your MacBook’s model number by clicking Apple logo > About This Mac.

2. Which specific MacBook models does this battery fit?
This battery is compatible with the following models and their corresponding EMC numbers:

  • MacBook Retina 12″ (2017) – Model A1534, EMC 3099

  • MacBook Retina 12″ (2016) – Model A1534, EMC 2991

  • MacBook Retina 12″ (2015) – Model A1534, EMC 2746

3. My MacBook is a 2015 model, but the original battery was an A1582. Will the A1527 work?
Yes, absolutely. The A1527 is the direct replacement part for the original A1582 battery used in the 2015 MacBook 12″. Apple often updates part numbers, and the A1527 is the correct and compatible battery for your device.

Product & Quality

4. Is this a genuine, high-quality battery?
Yes, this is a premium-grade, genuine-specification replacement battery. It is manufactured to meet or exceed the original Apple battery’s specifications, ensuring the same performance, safety, and reliability. It features the exact same 7.56V and 41.41Wh rating as the original.

5. How is this battery different from a used or refurbished battery?
Our batteries are brand new. Unlike used or refurbished batteries that have degraded over time, our cells are fresh from production, ensuring you get the full lifespan and maximum battery health right from the start.

6. Will this battery work with macOS and show accurate battery percentage?
Yes. Because it is a genuine-specification battery, it will be fully recognized by your MacBook’s system. macOS will display an accurate battery percentage, cycle count, and health status, just like the original.

Installation & Use

7. Is it difficult to replace the battery myself?
Replacing the battery in a MacBook 12″ is a moderate to advanced DIY repair. The back case is glued on, requiring careful prying and the use of specialty tools like a pentalobe screwdriver and spudgers. We highly recommend watching a detailed tutorial video before attempting.

8. Do you provide an installation guide or tools?
Yes! We include a step-by-step installation guide. For your convenience, we also offer tool kits that can be purchased separately or as a bundle, containing all the necessary pentalobe screwdrivers, spudgers, and plastic opening tools to perform the repair safely.

9. Do I need to calibrate the new battery after installation?
Yes, for optimal performance, it’s a good practice to calibrate your new battery. After installation, simply charge it to 100% without interruption, then use your MacBook on battery until it goes to sleep (about 5% charge). Finally, charge it back to 100% in one go.

Performance & Warranty

10. What is the expected battery life and performance?
You can expect performance identical to a new, original Apple battery. With a full 41.41Wh capacity, you should get back to the standard 8-10 hours of wireless web browsing or video playback that your MacBook had when it was new.

11. How many cycles can this battery handle?
This high-quality battery is rated for up to 1000 charge cycles while maintaining a significant portion of its original capacity, matching the performance standards of the original Apple battery.

12. What warranty do you offer on this battery?
We stand behind our products. This Genuine A1527 A1705 Replacement Battery comes with a robust [e.g., 24-month or 2-year] warranty and dedicated customer support. Please see the product page for full warranty details.

Shipping & Support

13. How quickly will my order ship?
We pride ourselves on fast fulfillment. Most orders are processed and shipped within 24 hours on business days.

14. What if I have issues with the installation or the product itself?
Our dedicated customer support team is here to help. If you encounter any issues during installation or have concerns about the battery’s performance, please contact us directly through the storefront or your order confirmation email for prompt assistance.
