How to Install Your New A1502 / A1582 Battery:

Replacing the battery in an A1502 MacBook Pro requires patience and the correct solvent to loosen the adhesive.

⚠️ Crucial Safety Preparation

• Discharge First: Discharge your battery to below 25% to reduce the risk of thermal runaway if a cell is accidentally punctured.
• Required Tools: P5 Pentalobe screwdriver (for bottom case), T5 Torx screwdriver, and Adhesive Remover (or 90%+ Isopropyl Alcohol).

Step-by-Step Installation Guide:

1. Remove the Bottom Case:
   Flip the MacBook over and use the P5 Pentalobe screwdriver to remove the 10 screws. Lift the case off. 
2. Disconnect the Battery:
   Locate the battery connector. Remove the plastic cover and use a spudger to lift the connector straight up. This is vital to protect the logic board.
3. Clear the Path:
   You may need to remove the two speaker modules on the sides to gain better access to the battery’s outer cells.
4. Loosen the Adhesive (The Critical Step):
   Apply a small amount of Adhesive Remover or alcohol under each battery cell. Let it sit for 2-3 minutes.
   Gently slide a plastic card or spudger under the cells to lift them. DO NOT use metal tools as the A1502 battery cells are very soft and easily punctured.
5. Install the New Battery:
   Clean the old glue from the chassis. Remove the adhesive backing from the new A1582 battery.
   Align the battery connector with the motherboard BEFORE pressing the cells down to ensure it sits perfectly.
6. Reassemble and Calibrate:
   Reconnect the speakers and battery cable. Reinstall the bottom case.
   Calibration: Fully charge to 100%, keep it plugged in for 2 hours, then discharge to 0%. Charge it back to 100% uninterrupted.

💡 Pro Tip: -H2

Model Differentiation: The A1582 battery is incompatible with the A1425 laptops from 2012 to early 2013 (even though both are 13-inch Retina models). 

Installation Tools:  Since a solvent is needed to remove the adhesive, it is strongly recommended that users prepare an “adhesive remover” or “alcohol wipes.”

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 out of 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.
