This document provides a detailed guide for replacing the battery in a MacBook Air (Retina, 13-inch, 2018/2019) model. It outlines a step-by-step procedure, from initial preparation to the final reassembly and calibration of the new battery.

Function Description:

The primary function of this guide is to facilitate the replacement of a built-in Li-Ion Polymer battery in specific MacBook Air models. The battery serves as the main power source for the laptop, enabling portable operation without a direct connection to an electrical outlet. Replacing the battery is a maintenance procedure aimed at restoring or improving the device's battery life and overall performance, especially when the original battery has degraded over time.

Important Technical Specifications:

The replacement battery specified in this guide is an LMP Battery for MacBook Air 13" Thunderbolt 3.

Compatibility: MacBook Air (Retina, 13-inch, 2018) and MacBook Air (Retina, 13-inch, 2019).
Part Number (P/N): 23195.
Type: Built-in, Li-Ion Polymer.
Voltage: 11.4 V.
Capacity: 50 Wh.
Manufacturing Date Range: 10/18 - 3/20.

Usage Features (Related to the Replacement Process):

The guide emphasizes several key features and considerations for users undertaking the battery replacement:

Required Tools: The procedure necessitates specific tools, including a Pentalobe P5 screwdriver, Torx T5 and T3 screwdrivers, a spudger with flat and pointed ends, and tweezers. It notes that all these tools are available in the LMP Toolkit (P/N 16262), sold separately.
Additional Equipment: Isopropyl wipes are recommended for cleaning.
Safety Precautions:
- Professional Recommendation: It is highly recommended that an experienced technician perform the procedure due to the complexity and potential for damage or injury. LMP disclaims responsibility for any issues arising from the procedure.
- Battery Discharge: Before starting, the MacBook's battery should be discharged to at least 20% or lower to minimize the risk of a thermal event.
- Power Off: The MacBook must be completely turned off before beginning the disassembly.
- Fragile Components: Warnings are provided regarding the fragility of components like the trackpad cable and Touch ID cable, emphasizing careful handling to prevent damage. Damage to the Touch ID board, in particular, requires replacement by an Apple Authorized Service Provider.
- Adhesive Strips: Special "pull to release" adhesive strips are used for the speakers and battery. Users are advised to pull these strips slowly and gently to avoid breakage, as broken strips can make removal very difficult.
Organization and Screw Management:
- The procedure involves removing a large number of small screws and parts.
- Users are strongly advised to organize these components, for example, using an ice cube tray, to prevent loss and ensure correct reassembly.
- A critical warning is given that screws, while appearing similar, can vary slightly in length. Returning screws to their original positions is crucial to avoid damage during reassembly.
Step-by-Step Disassembly and Reassembly: The guide provides detailed visual and textual instructions for each step, covering:
- Removing the bottom case (Step 1-2).
- Disconnecting the battery connector (Step 3).
- Removing logic board components, including the USB-C board cable securing bracket (Step 4), speaker cables (Step 5), trackpad cable (Step 6), fan cable (Step 7), audio board cable (Step 8), antenna cables (Step 9-10), and display cable connector (Step 11).
- Removing the logic board itself (Step 12).
- Removing audio board components, including its securing bracket (Step 13), the audio board cable (Step 14), Touch ID cable (Step 15), and left speaker cable (Step 16).
- Removing the audio board (Step 17-18).
- Removing the trackpad cable from its adhesive (Step 19-21).
- Removing the speakers using adhesive strips (Step 22-24).
- Removing the battery, which is secured by adhesive strips and screws (Step 25-27).
Reassembly Instructions: The guide explicitly states that reassembly should follow the disassembly steps in reverse order (Step 34). Specific instructions are provided for installing the new battery, including applying new adhesive strips (Step 28-31) and securing it with screws (Step 31). Similarly, instructions for reinstalling speakers with new adhesive strips are included (Step 32-33).

Maintenance Features (Related to the New Battery):

Battery Calibration: After replacing the battery, full calibration is highly recommended. This involves:
- Charging the MacBook to 100%.
- Keeping it on charge for an additional 2-3 hours.
- Using the MacBook on battery power until it enters sleep mode due to low charge.
- Leaving it overnight or for at least 5 hours in sleep mode.
- Charging the battery back to 100%.
Troubleshooting: If any issues or strange behavior are observed after battery replacement, resetting the PRAM and SMC is recommended.
Adhesive Strip Replacement: The battery kit includes replacement adhesive strips for both the battery (8 short strips, 6 used for the battery) and the speakers (4 long strips, 2 used for the speakers), ensuring proper securement of these components during reassembly.
Cleaning: Isopropyl wipes are suggested for cleaning the raised sections of the housing before applying new adhesive strips for the battery, ensuring optimal adhesion.
