It depends on which year and model identifier you have, since this line spans roughly 77 models. Late 2010-2017 models (A1369/A1466) commonly use the A1405, A1496, or A1377 batteries, while the Late 2018-2019 A1932 uses the A1965 family. Newer machines like the 2020 A2179 use the A2255 family, and the M1 A2337 uses the A2389 family. Voltage runs about 10.8 to 11.26 V across the line, so check the model number on the bottom case before ordering.

Flip the laptop over and read the model identifier printed on the bottom case, which looks like “Model A1466” or “Model A2337.” That identifier, paired with the release year, points to the exact part family you need. For example, A1932 takes the A1965 family while A2179 takes the A2255 family, and these are not interchangeable. With 18 distinct part numbers across this line, the model number is the fastest way to narrow down to the correct one.

Replacement batteries for this line range from $34.99 to $87.99, depending on which model and part family you need. Older wedge-era models (A1369/A1466) using parts like A1405 tend to sit toward the lower end, while higher-capacity Apple Silicon batteries (up to about 95 Wh) fall toward the upper end. Confirming your exact model identifier first ensures you are pricing the correct battery rather than one from a different generation.

Only within the same era, and even then not always. The wedge-era A1369/A1466 models share cross-compatible batteries like the A1405, A1496, and A1377. But across generations they are not interchangeable, since the 2020 A2179 (A2255 family) uses a different connector than the 2018-2019 A1932 (A1965 family). With voltage spanning 10.8 to 11.26 V and 18 distinct part numbers, you should always match your specific model identifier rather than assume a battery will carry over.

The differences include cell layout, capacity, connector, and how the battery is mounted. The Late 2010-2017 A1369/A1466 uses a removable, screw-mounted wedge-shaped battery (A1405/A1496/A1377). The Late 2018-2019 A1932 uses a glued and screwed rectangular pack (A1965). The 2020 A2179 (A2255) changed the internal connector, and the M1/M2/M3 models (A2389 and A2687 families) optimize for higher capacity up to about 95 Wh, with M2/M3 using adhesive pull-tabs.

The part number family is tied to your laptop’s model identifier, printed on the bottom case as something like “Model A2337.” Once you have that, you can map it to the correct battery family: A1932 maps to A1965, A2179 maps to A2255, the M1 A2337 maps to A2389, and the M2/M3 models map to A2687. Common part numbers in this category include 020-6380-A, A1322557, and 661-5229. Match the model first, then confirm the part family.

Yes, with the right tools and patience. Most models need a Pentalobe 5-point (P5) screwdriver for the bottom case and a Torx T5 or T3 for the battery screws. The wedge-era A1369/A1466 batteries are simply screw-mounted, making them the most straightforward. Models from 2018 onward (like the A1932 using A1965) are glued in, and the 2022/2024 M2/M3 models use adhesive pull-tabs, so plan time to work through the adhesive carefully during removal.

Common signs include rapidly dropping charge, the laptop shutting down before reaching zero percent, the system reporting “Service Recommended” battery status, or no longer holding a charge near its original capacity. Since these packs run about 55 to 95 Wh, a noticeable drop in runtime compared to when the machine was new is a strong indicator. If your A1466 or A2337 will not power on without being plugged in, the battery has likely reached the end of its useful life.
