How to Install Your New A2389 Battery (A2337)

Because the battery is heavily glued to the casing and surrounded by delicate ribbon cables, replacing the battery in the A2337 is very difficult. Replacing the battery in a MacBook Air M1 (A2337) is a complex procedure. It requires professional tools and careful handling of the adhesive and trackpad flex cables.

⚠️ Crucial Safety Preparation

• Discharge First: Ensure the battery is below 25% before disassembly to prevent fire risks if a cell is punctured.
• Required Tools: P5 Pentalobe, T3 Torx, T5 Torx, and a Battery Adhesive Remover (or 99% Isopropyl Alcohol).

Step-by-Step Installation Guide

1. Remove the Bottom Case:
   Use the P5 Pentalobe screwdriver to remove the 10 screws. Carefully lift the bottom case off.
2. Disconnect the Battery Board (Critical):
   Locate the battery data connector. Use a T3 Torx to remove the cover screw, then lift the connector. This isolates the power to protect the logic board and M1 chip.
3. Clear the Path:
   You must remove the logic board and speakers to safely access all the battery’s adhesive pull tabs. This is a delicate process involving several small flex cables.
4. Dissolve and Remove Adhesive:
   Apply Adhesive Remover under the edges of each battery cell. Let it sit for 5-10 minutes.
   Warning: The trackpad flex cable is located directly under the battery. Use a thin plastic card to slide under the cells very slowly to avoid slicing the cable.
5. Clean and Install:
   Wipe away all remaining adhesive from the chassis. Remove the backing from the new A2389 battery’s adhesive strips.
   Align the battery connector with the motherboard BEFORE pressing the cells down into place to ensure a perfect fit.
6. Reassemble and Calibrate:
   Secure all screws, reconnect all flex cables, and close the case.
   Calibration: Charge to 100%, keep it on the charger for 2 hours, then discharge to 5%, and charge it back to 100% uninterrupted.

💡 Pro Tip:

Professional Recommendation: Due to the complexity of disassembling the A2337 and the high risk of damaging the touchpad ribbon cable, as well as the strong adhesive, professional installation is highly recommended to avoid damaging the internal components.

Laptop Maintenance Tips:

1. New battery: For using a new battery, you’d better try a few cycles of discharging to 5%. then charging up to 95%. So that it can be activated completely
2. Overuse: Do not always run a battery to 0%, as this would shorten its usage life.
3. Charging sequence: When charging, first install the battery, then turn on the power. When fully charged, first cut off the power, then pull the power plug.
4. Long-term storage: Please store the unused battery fully charged. (Charge it once a month.) Do not store at low power to prevent reducing the lifespan of a battery
5. Charger: Do not replace the laptop adapter casually. If the original adapter cannot be applied due to malfunction or damage, please replace the models so as not to reduce the service life of the battery due to incompatibility.
