77.5Wh A1382 Battery for MacBook Pro 15 in - Reliable Replacement

In this review the 77.5Wh A1382 replacement battery is evaluated as a direct swap for 15 in MacBook Pro models from Early 2011, Late 2011 and Mid 2012. The bottom line: this pack is aimed at owners who need a like-for-like capacity and voltage match to restore runtime and fit without modifying the machine. The reviewer found the battery meets factory-style specifications, installs with the included screwdrivers, and offers a practical, cost-effective way to revive aged MacBook Pro 8,2 and 9,1 machines.

Key Features

• 77.5Wh capacity: Provides the same rated energy as the original design so users can expect comparable runtime under similar workloads.
• 10.95V Li-Polymer chemistry: Matches the original battery voltage and chemistry to maintain safe charging and system reporting.
• 6-Cell construction: The 6-cell layout preserves physical fit and balance inside the A1286 chassis for proper seating and cooling.
• Compatibility and part numbers: Explicitly replaces A1382 and related part numbers such as 020-7134-A and 661-5211 so buyers can verify fit for their model.
• Certifications and safety: CE/UL/FCC and RoHS listings indicate the pack uses regulated materials and protective circuitry to reduce leak or contamination risk.
• Kit and warranty: Ships with two screwdrivers for installation and a one-year warranty with seller support for returns or exchanges.

Who It's For

This battery is for owners of 15 in MacBook Pro models identified as A1382 or A1286 from Early 2011, Late 2011, or Mid 2012 who want a direct replacement that preserves original capacity and voltage. It also suits users comfortable performing a straightforward internal swap using basic tools, since two screwdrivers are included to make the job faster.

Those who should look elsewhere include users with other MacBook generations or models, or anyone requiring extended runtime beyond the original 77.5Wh capacity. If you need professional installation or prefer a battery with a significantly higher capacity than factory specification, consider a repair service or a different product offering.
