When macOS displays a “Service Recommended” battery warning—or your MacBook shuts down at 30% charge, or the trackpad suddenly stops clicking because a swollen battery cell is pressing up from underneath—replacing the battery breathes years of portable life back into your laptop.
However, Apple used four completely different battery mounting architectures across its MacBook Air and MacBook Pro lines. Following a guide meant for a 2015 MacBook on a 2020 M1 MacBook will result in a torn trackpad cable or a ripped motherboard power terminal.
Find your MacBook’s Model Number (Axxxx) printed in microscopic text on the underside of your laptop’s aluminum bottom cover, and follow the exact technician protocol for your chassis below.

Critical Safety Warnings Before You Begin
[!CAUTION] 1. DO NOT Attempt DIY Removal on a Visibly Swollen Battery!
If your battery pouches are puffy, bulging, pushing the trackpad upward, or bowing the aluminum case, stop immediately and do not attempt DIY removal at home. Swollen lithium-ion cells contain pressurized, flammable electrolyte gas and can enter violent thermal runaway (intense fire and toxic hydrofluoric/fluoride fumes) if flexed, punctured, or exposed to solvents. Power the MacBook off, do not charge it, and bring it to a professional repair facility equipped with fire-safe containment.2. Drain Non-Swollen Batteries Below 15% First:
Before servicing any normal (flat, non-swollen) battery, discharge it below 15%. A low state of charge drastically reduces stored thermal energy. Always wear ANSI-rated safety glasses and work on a clean, non-flammable surface.3. 99% Isopropyl Alcohol Flammability & Display Seepage Warning:
99% Isopropyl Alcohol (IPA) and its vapors are highly flammable. Never use a heat gun, hairdryer, or open flame anywhere near IPA. Only apply minimal drops along adhesive edges—never flood or pool liquid inside the laptop, as excess alcohol will wick into the display assembly and permanently ruin the LCD backlight diffuser layers.
Group 1: MacBook Air 2013–2017 (A1466) — The 5-Minute Screw-In Swap
If you own the classic silver-bezel MacBook Air (A1466 or 11-inch A1465), congratulations: Apple engineered this battery as a modular plastic frame held in by 5 simple screws and zero adhesive.
- Remove Bottom Cover: Use a P5 Pentalobe driver to remove the 10 bottom case screws (keep the 2 long top-center screws separate).
- Unplug the Battery: Pull the clear plastic tab on the battery connector straight toward the front edge of the laptop.
- Remove the 5 T5 Torx Screws: Unscrew the two screws at the left/right wings, the two at the bottom corners, and the one screw in the top-center of the battery frame.
- Drop In the New Battery: Lift the old battery out, set the new one in place, fasten the 5 T5 screws, plug the battery cable in, and close the cover. Done!
Group 2: Retina MacBook Pro 2013–2015 (A1502 & A1398) — The 99% Alcohol Solvent Method
On the 2013–2015 Retina MacBook Pros, the 6 individual lithium pouch cells are bonded directly to the aluminum top case using industrial 3M VHB foam tape. Never try to pry these up dry with a metal screwdriver.
Step-by-Step Safe Removal Protocol:
- Open & Disconnect: Remove the 10 P5 Pentalobe bottom screws and pop the battery connector straight up off the logic board using a nylon spudger.
- Protect the Trackpad Cable (A1502 13-inch): Look closely at the two center battery cells. The silver/black trackpad ribbon cable runs directly underneath them! Unplug and peel back the trackpad cable first so you cannot slice it.
- Apply 99% Isopropyl Alcohol (IPA):
- Use a syringe or pipette to drip 1–2mL of 99% IPA into the gaps between the outer four battery cells.
- Let the laptop sit flat for 3 full minutes so capillary action wicks the alcohol underneath the foam tape and dissolves its bond.
- Slice with Nylon Cord or Plastic Cards:
- Slide a flexible plastic playing card or heavy waxed nylon cord underneath the outer cells using a gentle sawing motion.
- Work from the outside cells inward, keeping your card flat against the aluminum floor so you never bend or crease the soft silver battery pouches.
- Clean Before Installing the New Battery: Wipe all residual alcohol and old glue off the aluminum frame until bone-dry before peeling the backing off your replacement battery’s adhesive strips.
Group 3: MacBook Air Retina & M1/M2/M3 (A1932, A2179, A2337, A2681) — Stretch-Release Tabs
Starting in 2018 (and continuing through the M1 A2337 and M2/M3 MacBook Airs), Apple replaced permanent foam glue with 3M Stretch-Release Pull Tabs (like Command strips) paired with perimeter T3/T5 Torx screws.
- Disconnect the Battery Terminal First: Unplug the press-fit battery connector from the logic board.
- Loosen or Remove the Left & Right Speakers: On
A1932,A2179, andA2337, the speaker enclosures slightly overhang the outer battery wings. Unscrew and lift the speakers aside gently. - Pull the Stretch Tabs Low and Slow:
- Use blunt tweezers to peel up the black adhesive pull-tab tips along the battery edges.
- Wind the tab around the tip of your tweezers and pull horizontally at a low 15-degree angle—slowly and steadily.
- If a tab snaps mid-pull, don’t panic: apply a few drops of 99% Isopropyl Alcohol under that cell corner and slide a plastic card underneath to release the remaining strip.
- Remove the 4 Corner T5 Screws: Unscrew the four perimeter frame screws and lift the entire battery frame out cleanly.
Group 4: MacBook Pro USB-C & M1/M2 13” (A1706, A1708, A1989, A2159, A2289, A2338) — The BMU Cable Trap!
[!CAUTION] Read This Before Touching the Battery Connector on Any 2016–2022 13” MacBook Pro! These models do NOT use a standard plug-in battery cable. They use a two-part connection: a tiny ZIF data ribbon cable AND a heavy gold power tab held down by a single T5 screw. If you unscrew and lift the gold power tab before disconnecting the tiny black data ribbon, you will rip the battery controller socket right off the motherboard!
Exact Disconnection Sequence (Do Not Reverse!):
- Peel Back the Black Plastic Cover Sticker sitting directly over the battery terminal at the center of the board.
- Flip Open the Tiny ZIF Locking Bar on the small black BMU data flex cable and slide the tiny ribbon out of its socket using tweezers.
- Unscrew the Single T5 Torx Screw holding the thick gold battery power tab down against the board.
- Bend the Gold Power Tab Slightly Upward (about 15 degrees) so it no longer makes electrical contact with the brass standoff underneath.
- Dissolve Adhesive & Avoid the Trackpad Flex: Just like the 2015 model, use 99% Isopropyl Alcohol and plastic cards to release the 6 glued cells, taking extreme care around the center cell directly over the trackpad flex cable.
Post-Install SMC Reset & Battery Calibration
After installing your new battery and reassembling the bottom case:
- Intel Macs: Hold Control + Option (Left) + Shift (Right) for 7 seconds, then hold the Power button as well for another 7 seconds to reset the System Management Controller (SMC) so macOS recognizes the new battery health capacity.
- Apple Silicon Macs (M1/M2/M3/M4): Simply shut the Mac down completely, wait 30 seconds, and boot back up—the power management IC calibrates automatically.
- Initial Charge Cycle: Charge the new battery to 100%, keep it plugged in for an extra 30 minutes, then use the laptop on battery power down to 15% before recharging to calibrate the fuel gauge percentage accurately.
