Replacement battery for 15-inch MacBook Pro
This lithium-ion pack replaces Apple part numbers A1707 and A1820 in Late 2016 and Mid 2017 Touch Bar models. It is a new unit built with quality cells and an integrated smart chip for system communication. Installers receive tools and pre-applied double-sided tape, though no printed guide is included.
76 Wh capacity and daily runtime
The 76 Wh rating matches the original specification, delivering comparable run time for typical workloads such as office applications, web browsing and media playback. Heavier sustained loads like video rendering or virtual machines will deplete the charge more quickly. The 11.4 V output maintains compatibility with the host power-management system.
Limits of the internal connector and form factor
The battery connects through the proprietary Apple interface used on the A1707 chassis, so it cannot be used in earlier 15-inch models or later 16-inch designs. Physical dimensions are fixed to the original enclosure, preventing any capacity increase beyond the factory 76 Wh. Professional installation is advised because the pack is glued in place and requires careful disassembly.

Questions about this item
Will the 76Wh 11.4V lithium-ion cell fit the original A1707 chassis without bending the trackpad cable?
The battery matches part numbers A1707 and A1820 for MacBook Pro 15-inch Late 2016 and Mid 2017 Touch Bar models, so it occupies the same internal volume as the factory pack.
How can I verify the 6667mAh capacity is reporting correctly in macOS after installation?
Open System Information → Power and confirm the cycle count starts at zero and the full charge capacity reads near 76Wh once calibrated.
Are the pentalobe and tri-wing screwdrivers plus adhesive strips included so I do not need a separate kit?
Tools are included and double-sided tape is either pre-applied or supplied in the package; no separate adhesive purchase is required.
