Battery BTI A1281-BTI MacBook Pro 15

Restore practical battery life to supported Apple MacBook Pro 15-inch aluminum notebooks with this BTI replacement pack. Built for MB470J/A and MB470LL/A, the A1281-BTI is a focused service part for systems that still need reliable portable power without the cost of a full machine replacement. The battery uses lithium-polymer chemistry and delivers 10.8 V DC with 5,400 mAh capacity, giving compatible notebooks the electrical profile they expect. That matters in enterprise and repair environments where fit, voltage, and chemistry must align with the original design to avoid guesswork and reduce downtime. An 18-month limited warranty adds confidence for procurement teams and service desks that need a replacement part with a clear support window. For organizations maintaining older MacBook Pro fleets, this battery helps preserve user mobility, extend asset life, and keep repair costs controlled. It is a practical choice when the notebook itself is still serviceable, but the battery has reached end of life.
