Replacement battery for 13-inch MacBook Pro

The KingSener A1964 is a lithium-ion replacement battery built for MacBook Pro 13-inch models from 2018 to 2020. It matches the original 58.0WH capacity and 11.41V voltage across part numbers A1989, A2251 and EMC 3214, 3358, 3348. Owners of MR9Q2, MV962 or MWP42 series machines can restore factory runtime with a direct-fit unit. The black pack installs using the existing screw points and connector.

Thermals noise and power draw

Lithium-ion chemistry delivers steady 11.41V output with low internal resistance, so the system draws consistent current during typical workloads. The 5086mAh cell count supports the original thermal profile without extra heat or fan activity. No moving parts means silent operation and no added acoustic load. Power efficiency remains identical to the Apple-supplied pack under normal use.

Upgrade from depleted original cells

This battery replaces a worn or swollen Apple 080-333-4000 unit when cycle count exceeds service limits or runtime drops below usable levels. The jump is worth it when the MacBook shuts down early, throttles on battery or shows a service-recommended alert. It is not for users needing higher capacity than 58.0WH, machines outside the 2018 to 2020 13-inch range, or non-Apple laptops.

Questions about this item

How do I install the KingSener A1964 battery in my MacBook Pro 13-inch, and which step is most often done incorrectly?

Remove the bottom case screws, disconnect the trackpad flex cable, then unplug the old battery connector before unscrewing its retaining screws; the step most often missed is reconnecting the trackpad cable before closing the case.

What future maintenance or replacement will the KingSener A1964 battery require?

The 58.0WH lithium-ion pack will gradually lose capacity over repeated charge cycles; plan to replace the unit when run-time no longer meets your workload.

What limit appears first during sustained heavy use of the KingSener A1964 battery?

The 11.41V 5086mAh cells will hit thermal and voltage sag limits under continuous high load, reducing available power before the pack is fully drained.
