Compatible MacBook Pro models

This Oemstation A1618 battery replaces the original cell in Apple MacBook Pro 15.4 inch Retina models A1398 with EMC 2909 or 2910 from mid 2015. It matches the factory voltage of 11.36 volts and a capacity of 99.5 watt-hours. The pack is rechargeable and ships as a single unit weighing 15 ounces.

Installation requirements

The replacement fits directly into the existing battery bay without adapters or cable changes. A stainless-steel S2 screwdriver kit, a helper stick and the battery manual are included so the swap can be completed with basic hand tools. No soldering or firmware updates are needed.

Capacity and runtime

The 8700 milliampere-hour rating restores the original runtime envelope for web browsing, video playback and light development work. Heavy sustained loads such as rendering or virtual machines will deplete the charge faster than the factory specification. The battery is not compatible with any MacBook Pro outside the listed A1398 mid-2015 models.

Questions about this item

How long can the 99.5 Wh capacity sustain typical workloads before the battery needs recharging?

The 99.5 Wh capacity is rated for up to 8700 mAh, which determines how long the MacBook Pro 15.4" A1398 Mid 2015 runs on a single charge under normal use.

Does the replacement battery generate more heat or fan noise than the original during all-day operation?

The battery operates at the same 11.36 V as the original Apple A1618 cell, so thermal output and acoustic profile remain unchanged during sustained workloads.

Which MacBook Pro models and EMC numbers must I already own for this A1618 battery to be compatible?

This battery fits only Apple MacBook Pro 15.4" Retina A1398 with EMC 2909 or EMC 2910 from Mid 2015; verify the model number on the bottom case before ordering.
