Direct replacement for 13-inch Retina A1502

This new lithium-ion battery matches the original A1582 and part number 020-8148. It is built for MacBook Pro Retina 13-inch models from Early 2015 with EMC 2835, including the 2.5 GHz Core i5, 2.9 GHz Core i5 and 3.1 GHz Core i7 variants. The 74.9 Wh capacity and 11.42 V voltage restore factory runtime.

Fits inside the existing chassis without

The pack slides into the same battery bay and connects to the stock motherboard header, so no extra cables, adapters or firmware steps are required. It frees the user from a degraded or swollen original cell and returns the notebook to portable operation. Buyers needing a higher-capacity design or a different form factor will not be served by this unit.

Runs at stock voltage with no active cooling

The lithium-ion chemistry operates within the laptop's thermal envelope, drawing power only during charge cycles and delivering steady output on battery. No fan or heatsink is involved, so acoustic profile is unchanged from the original. The 12-month warranty covers defects in materials and workmanship under normal use.
