Replacement battery for 15-inch MacBook Pro
This 5600 mAh lithium-ion polymer pack is built for the 15-inch MacBook Pro models identified as A1321, A1286 (2009 version), MB985, MB986 and MC118. It restores portable power to machines from the 2009 and 2010 period that no longer hold a usable charge.
Thermals noise and power draw in normal use
The 11.1 V, six-cell design delivers the rated capacity without adding active cooling or moving parts. In typical office workloads the pack runs silently and stays within the thermal envelope defined by the original chassis, drawing only the current the system requests.
Upgrading from a depleted original pack
This unit replaces an exhausted or swollen factory battery that can no longer sustain a full work session. The jump is worth it when the MacBook shuts down unexpectedly, reports a service-battery warning or provides less than an hour of unplugged runtime. It does not add capacity beyond the original 5600 mAh specification.

Questions about this item
How do I install this A1321 battery in my MacBook Pro 15" and what step is often missed?
Power off the laptop, remove the bottom case screws, disconnect the old battery connector, fit the new 6-cell 11.1 V pack, reconnect the cable securely, then replace the case and screws before turning on.
What maintenance or replacement will this 5600 mAh Li-ion polymer battery need later?
The battery will gradually lose capacity over charge cycles; when runtime drops below your needs, replace the entire pack as cells are not user-serviceable.
What limit appears first during sustained use of this 11.1 V battery?
The 5600 mAh capacity determines runtime; under continuous load the pack will deplete and require recharging before voltage drops too low.
