MacBook Battery A2797 - OEM Quality For Reliable Repairs
Choose MacBook Battery A2797 - OEM Quality when you need a drop-in replacement that behaves like the original pack. You get a fresh, 0‑cycle unit built with oem‑grade cells and a smart management board that communicates correctly with macos battery health features. You install it, calibrate it, and send the device back to your customer with stable runtime and accurate percentage reporting.
The pack is engineered for consistent discharge curves and tight matching to keep idle drain low and peak draw steady under load. The protection circuitry covers overcharge, over‑discharge, overcurrent, and temperature events, and the board layout follows the original footprint so screw points, flex orientation, and connector alignment match the A2797 assembly. You get predictable charging behavior, proper sleep‑wake performance, and no error prompts.
Technical data and build details
This is a lithium‑ion polymer multi‑cell assembly with a smart bms tuned to the A2797 specification. Capacity and nominal voltage are matched to the original MacBook profile so the system controller reads design capacity, full charge capacity, and cycle count correctly after calibration. Cells are binned by internal resistance and age code so each pack ships with balanced series groups for even wear over time.
Each unit is assembled with flame‑retardant separators, nickel current collectors, and a precision ntc for accurate thermistor feedback. The board uses quality mosfets and a proven protection ic to manage cutoff thresholds. The flex and connector follow the oem pinout, and the pack perimeter accepts new adhesive strips for secure seating in the top case. The finish is clean and ready for adhesive prep, reducing rework during installation.
Compatibility and use cases
Use this pack in MacBook units that specify battery model A2797 on the original label or in service documentation. If you refurbish fleets or handle board swaps, A2797 is a safe choice when the machine expects that exact battery code, ensuring firmware alignment and correct fuel gauge behavior. Typical repair scenarios include swollen packs, rapid capacity loss, unexpected shutdowns at percentages, and machines throttling under load due to voltage sag.
For shops, A2797 suits same‑day turnarounds and bulk refresh projects where consistency matters. You reduce callback risk because the device reports health metrics as expected, sleep current stays within normal range, and charge termination behaves correctly with usb‑c power adapters and docks. You can standardize on one part code for intake, inventory, and quality checks.
Installation, handling, and aftercare
Power down the MacBook, disconnect the battery before any other internal work, and remove adhesive with controlled heat and isopropyl where needed. Avoid prying near flex zones and do not twist the cells. Clean bonding surfaces and apply new adhesive strips prior to setting the pack. Connect the flex last, confirm connector seating, and perform a post‑assembly check before closing the housing.
Calibrate after installation so the fuel gauge aligns with the new design capacity. Charge to 100 percent, keep it connected for a short stabilization period, then discharge to a low state of charge and recharge to full. Store spares at a partial state of charge in a cool, dry environment, and avoid long‑term storage at full or empty. With proper handling, you deliver reliable runtime and predictable wear that your customers can trust.
The battery is covered with a 1-year product warranty. The warranty does not cover man-made damage or wear and tear. To be used with MacBook model number: A2941, A3114
