MacBook Battery A2977 - OEM Quality For Reliable Repairs
Get consistent performance and fast turnaround with MacBook Battery A2977 - OEM Quality. You receive a fresh, zero‑cycle pack built to match the original specification so you can restore runtime and stability without callbacks. The pack arrives with an integrated fuel gauge board that communicates correctly with macOS, enabling accurate percentage reporting, normal charging behavior, and proper sleep and wake. Cell matching and balancing are factory set, which helps deliver steady discharge curves under typical office, creative, service bench workloads.
OEM grade materials and assembly deliver reliable fit and finish for units designed for the A2977 code. The enclosure, flex, and mounting layout mirror the original design, so installation is straightforward and repeatable across your workflow. Safety features include hardware overcharge protection, over‑discharge cutoff, short‑circuit protection, and thermal safeguards to protect both the computer and the pack during charge, discharge, and storage.
Technical Data For MacBook Battery A2977
Part code is A2977 with OEM quality cells in a lithium‑ion polymer multi‑cell pack. The pack is engineered to the same nominal voltage class used by the original battery, delivering stable system power and correct charger handshaking. The integrated battery management system provides cell balancing, charge control, and a calibrated fuel gauge so health metrics, cycle count, and remaining capacity are tracked as expected in macOS. The connector and flex layout match the factory design for a drop‑in fit with the original bracket and screw pattern used in A2977‑equipped units.
The pack the typical MacBook usage profile with rapid top‑off charging, sustained discharge for long sessions, and idle efficiency during standby. Cycle life is designed to meet modern MacBook expectations with strong retention across many charge cycles when operated within normal temperature and voltage ranges. Materials comply with common EU requirements for restricted substances and transport safety, supporting workshop logistics and cross‑border shipments.
Compatibility And Use Cases For Repair Shops
Choose this battery when the unit you service specifies A2977 on the original pack label or parts database. The assembly suitable for board‑level repair centers, high‑volume refurbishers, and local service shops that need predictable quality and consistent batches. It is a strong option for devices failing diagnostics with high cycle counts, sudden shutdowns under load, swollen cells, or irregular percentage jumps after partial charge.
You can deploy it for complete refurb lines, warranty replacements, or post‑liquid treatment where the original pack shows elevated impedance. Accurate fuel gauging simplifies quality control checks after installation, and steady voltage delivery reduces retest time before returning the device to your client.</>
Installation And Handling Notes For Faster Turnaround
Power down the MacBook, disconnect the battery before other internal work, and protect the board from accidental bridging during removal. Use ESD‑safe tools, replace adhesive with fresh strips or approved equivalent, and avoid bending the pack during extraction or placement. After reassembly, perform a full charge to 100 percent and then a normal discharge cycle to help macOS learn the new pack’s range for more precise percentage reporting.
Store spares at partial charge in a cool, dry environment and avoid prolonged deep discharge to preserve cell health. Follow standard workshop safety, including insulating exposed contacts, controlling heat when softening adhesive, and verifying that the flex is fully seated before first boot. This approach keeps installation repeatable, reduces come‑backs, and maintains the service life you and your customers expect from MacBook Battery A2977 - OEM Quality.
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: A2992
