Replacement battery for MacBook Pro 15 Retina A1398

This 11.36V 99.5Wh lithium-polymer pack replaces Apple part A1618 in Mid 2015 Retina models MJLQ2, MJLT2 and MJLU2. It fits the 15.4 inch chassis with EMC 2909 or 2910 and restores factory capacity for owners whose original cells have aged.

Thermals and power in daily use

The 6-cell design delivers 99.5Wh at 11.36V, matching the OEM voltage so the MacBook power management sees no difference. Li-polymer chemistry runs cool under normal loads and the manufacturer rates the pack for up to 500 recharge cycles before capacity drops noticeably.

Build quality and included tools

CE FCC and RoHS certified cells are housed in a black enclosure that aligns with the original battery screw points. Two screwdrivers are supplied in the box so the ten pentalobe and tri-wing fasteners can be removed and refitted without sourcing extra tools. Buyers needing a higher-capacity pack or a battery for a different MacBook generation will not be served by this model.

Questions about this item

How do I install the A1618 battery in my MacBook Pro 15" Retina A1398 Mid 2015, and which step often goes wrong?

Remove the bottom case screws with the included screwdrivers, disconnect the old battery connector, fit the new 6-cell 11.36V 99.5Wh pack, reconnect it, then replace the case; the step people get wrong is forgetting to disconnect the battery connector before removing the old cells.

What maintenance or replacement will the Li-Polymer A1618 battery need later?

The 6-cell Li-Polymer pack is rated for up to 500 recharge cycles; after that capacity drops noticeably and a replacement battery will be required.

What limit appears first during sustained heavy use of this 99.5Wh battery?

The 500-cycle lifespan is the first hard limit; thermal throttling or voltage sag may occur earlier under continuous high load, but cycle count ultimately determines service life.
