Select Power from the hardware list.
-
Check the Model Information and Cycle Count. A genuine battery will show accurate manufacturer details and start with a cycle count of 1.
4. What are the technical specifications?
5. Can I install this battery myself?
We strongly discourage self-installation. Modern MacBook Air models have batteries that are securely glued to the top case. Replacement requires:
-
Specialized tools (P5 Pentalobe, T5 Torx screwdrivers).
-
Expertise to safely handle adhesive strips without damaging internal components.
-
Knowledge of the battery management system (BMS) to avoid short circuits.
To prevent serious damage and ensure safety, this repair must be performed by an Apple Authorized Service Provider (AASP) or a highly skilled professional technician.
6. Will installing this battery myself void my MacBook’s warranty?
If your MacBook is still covered by Apple’s standard warranty or AppleCare+, having the battery replaced by a non-authorized provider will void the remaining warranty for any future issues. For warranty protection, always use an Apple Authorized Service Provider.
7. What is the expected cycle count for this new battery?
This is a brand new, genuine Apple battery with a 0-1 cycle count. Apple designs these batteries to retain up to 80% of their original capacity at 1000 complete charge cycles.
8. Does the battery come with a warranty?
When purchased as a part and installed by an Apple Authorized Service Provider, it is covered by Apple’s limited warranty for parts. If purchased from a third-party seller for installation elsewhere, the seller may offer their own warranty. Please check the specific product listing for details.
9. What tools are required for a professional installation?
A professional will use:
-
P5 Pentalobe screwdriver for the bottom case.
-
T5 Torx screwdriver for internal components.
-
Battery adhesive removal tools (plastic cards, solvent).
-
ESD-safe workspace and tools.
-
New adhesive strips for securing the new battery.
10. How should I dispose of the old battery?
Lithium-ion batteries are hazardous waste and must not be thrown in the trash. You can return your old battery to any Apple Store or Apple Authorized Service Provider for free recycling. Many electronics retailers also offer battery recycling programs.
