FOCUSTEC 49.9Wh Li-Polymer battery for MacBook Air
This replacement battery fits MacBook Air 13 inch models A1932 and A2179 released in 2018 2019 and 2020. It is built for owners who need a new power source that matches the original 11.4V specification. The cell uses Li-Polymer chemistry and includes a smart chip for circuit protection and stable current delivery. It is not compatible with model A2337 or any other MacBook variant.
49.9Wh capacity and 500 recharge cycles
The 49.9Wh 4379mAh pack restores the factory runtime for everyday browsing document work and video playback. After roughly 500 full cycles the capacity will gradually diminish and the battery will no longer hold a full day of charge. The smart chip manages voltage and low self-discharge so the pack stays ready during storage. Heavy workloads that draw maximum power will reduce the per-charge runtime compared with light use.
CE FCC RoHS certified build with model-specific fit
Each unit is tested for correct voltage circuit protection and stable current and carries CE FCC and RoHS safety certifications. The battery is shaped to the exact internal dimensions of the A1932 and A2179 chassis so the trackpad and keyboard sit flush after installation. Because the connector and screw positions match the original part no adapter cables or modifications are required. Buyers who own a different MacBook Air model or who need a higher capacity than 49.9Wh must look elsewhere.

Questions about this item
Will the 11.4V 49.9Wh Li-Polymer battery work with the original MagSafe 2 charger I kept from my 2018 MacBook Air?
Yes, the battery is built to the same 11.4V specification as the original Apple A1965 cell, so the existing MagSafe 2 adapter will charge it normally.
How can I verify the new battery is recognised and healthy after I install it in my MacBook Air 13" A1932?
Open System Information → Power; you should see a cycle count near zero, full charge capacity close to 49.9Wh, and the condition listed as Normal.
Does the package include the pentalobe screws and adhesive strips needed to fit the battery in a MacBook Air 13" A2179?
The box contains only the battery itself; the pentalobe screws and adhesive strips must be sourced separately.
