The exact battery depends on which Apple MacBook 13″ you own, since the line covers about 77 models and 18 distinct part numbers. Voltage runs 10.8 to 11.26 V and capacity ranges from about 55 to 95 Wh, all lithium-ion. A 2006 to 2008 polycarbonate model uses an A1185 type pack, while a Unibody MacBook Pro 13″ uses an A1322. Check the A1XXX identifier on the bottom of your case to confirm the correct part. Each battery here is priced at $58.99.

Flip your Apple MacBook 13″ over and read the model identifier printed near the regulatory text on the bottom case, which looks like A1278, A1466, or A1989. Match that A1XXX number to the correct part, since the line spans 18 distinct part numbers across roughly 77 models. You can also cross-reference the part number on the existing battery, such as 020-6380-A or 661-5229. Matching the exact identifier matters because similar-looking models from different years take different batteries.

Replacement batteries for the Apple MacBook 13″ are priced at $58.99 across the catalog. That single price applies whether you need an early polycarbonate pack like A1185, a screwed-in Unibody A1322, or a glued Retina unit. Because the price is consistent, your main task is identifying the correct part number for your exact model rather than comparing costs. Confirm your A1XXX identifier before ordering so the battery matches your machine.

No, Apple MacBook 13″ batteries are not broadly interchangeable, even within the same family. The line uses 18 distinct part numbers spanning voltages of 10.8 to 11.26 V and capacities from about 55 to 95 Wh, and the physical shape changed significantly over the years. For example, a 2009 to 2012 Unibody MacBook Pro 13″ uses an A1322, while a Retina Touch Bar model uses a heavily glued unit like A1819. Always match your specific A1XXX identifier rather than assuming a battery from a similar model will fit.

The main differences are construction and accessibility. Polycarbonate MacBook 13″ models (2006 to 2010) used a user-removable pack like A1185 with a latch. Unibody MacBook Pro 13″ models (2009 to 2012) moved to an internal but screwed-in A1322. Later Retina, Touch Bar, and Apple Silicon models use thinner, higher-capacity internal cells (such as A1819 or A1988) that are heavily glued. Capacity also climbed over time toward the 95 Wh end of the range, and each family carries its own part numbers.

There are two places to look on a Apple MacBook 13″. First, the model identifier (A1XXX) is printed on the bottom case near the regulatory text, for example A1278 or A1466. Second, the battery itself often carries a printed part number such as 020-6380-A, 661-5229, or 020-5071-B once you open the case. Use the bottom-case identifier first since you can read it without any disassembly, then confirm against the battery label if needed.

Yes, though difficulty varies by model. Polycarbonate MacBook 13″ models (2006 to 2010) used a user-removable A1185 with a latch, the easiest swap. Unibody MacBook Pro 13″ models (2009 to 2012) use a screwed-in A1322, which is a straightforward DIY job. Retina, Touch Bar, and Apple Silicon models use heavily glued internal cells (such as A1819 or A2171), so they require patience, the right tools, and careful work. Identify your A1XXX model first to know which approach applies.

Common signs include a sharply reduced runtime, a battery that drains quickly or shuts down unexpectedly, and a macOS status showing Service Recommended. You may also notice the machine running only when plugged in or holding a much lower charge than its rated capacity of roughly 55 to 95 Wh. If your Apple MacBook 13″ no longer holds a useful charge, matching the correct part (such as A1322 or A1819) for your exact model is the next step, with replacements priced at $58.99.
