Compatible Replacement Battery

This CY battery replaces the original unit in MacBook Pro Retina 15-inch A1398 models from 2015. It uses Li-polymer cells rated at 11.26V and 8437mAh capacity. The part numbers A1494 and A1618 match the Apple components listed for these machines. It is built for users who need a direct swap without adapter changes.

Fits 2015 MacBook Pro Retina 15

The battery sits inside the existing chassis and connects to the stock logic-board header. No extra cables, brackets or firmware tools are required beyond the standard screws. Removing the old pack frees the trackpad cable route and restores full portable runtime. The 0.68kg weight matches the original balance.

Tested A-Grade Cells With Protection

Each pack undergoes ageing and install tests before packing, and the onboard circuit guards against over-charge and over-discharge. The 500 to 1000 cycle rating and 12-month warranty period reflect the supplier’s quality gate. FCC, CE, UL, MSDS and RoHS certificates cover the cell chemistry and assembly.

Questions about this item

Will the 8437 mAh capacity hold up after months of daily charging cycles?

The battery uses A-grade Li-polymer cells rated for 500 to 1000 charge cycles while retaining usable capacity.

Does the 11.26 V pack run hot or make fan noise during all-day use?

No moving parts exist in the battery itself; heat and noise depend on the laptop workload, not the replacement cell.

Must I already own a MacBook Pro Retina 15-inch A1398 from 2015 for this to fit?

Yes, it is designed for A1398 2015 models including part numbers MJLQ2, MJLT2, ME293, ME294, MGXA2 and MGXC2.
