The MacBook Pro 14″ uses a lithium-ion battery rated between 10.8 and 11.26 V, with capacity from about 55 to 95 Wh depending on the model and chip generation. Across the line there are 18 distinct part numbers covering around 77 compatible models, including identifiers like 020-6380-A and 661-5229. Because the same chassis was used from 2021 onward, the right pack depends on your exact model number (for example A2442 or A2779) and the year printed on the bottom case.

Flip the laptop over and read the model number on the bottom case, which looks like A2442, A2779, A2918, or A2992, then note the year and chip (M1 2021, M2 2023, or M3 2023). Match that to the battery listings, since 18 different part numbers cover roughly 77 compatible models. Capacity can differ, with some generations near 70 Wh and others closer to 73 Wh, so the case model number is the most reliable way to land on the correct pack.

Replacement batteries for the MacBook Pro 14″ run from $69.99 to $87.99, with the exact price depending on which part number fits your model and year. A higher-capacity pack for a Pro or Max configuration tends to sit toward the top of that range, while standard configurations land lower. Confirm your model number (such as A2442 or A2918) so you order the part matched to your machine’s capacity, anywhere from about 55 to 95 Wh.

Not always. Even though the 2021 through 2023 models share the same 14.2-inch chassis, the line uses 18 distinct part numbers and capacity varies by generation (some near 70 Wh, others around 73 Wh). A battery built for a 2021 M1 model (A2442) is not guaranteed to match a 2023 M3 model (A2918). Always confirm the model number on the bottom case and the year before assuming two packs are interchangeable.

The main differences are capacity, voltage, and part number across model years. Voltage ranges from 10.8 to 11.26 V, and capacity spans about 55 to 95 Wh, with later M3 models generally using a slightly larger pack than the 2021 M1 and 2023 M2 versions. There are 18 part numbers in total, including examples like 020-5071-B and MA348LL/A, so the generation and chip your machine carries determines which one fits.

Turn the MacBook Pro 14″ over and look at the model number etched on the bottom case, which appears as an A followed by four digits (for example A2442, A2779, or A2992). That model number, combined with the year and chip, maps to the correct battery part number, such as 661-5229 or 020-6380-A. With 18 part numbers covering about 77 models, the case marking is the quickest way to identify the exact battery you need.

Yes, but it is an involved job because the battery is bonded into the chassis. You will need a specialized toolkit that includes pentalobe and Torx drivers, the kind sold in repair kits. Plan for careful work since the factory battery is rated for around 1,000 charge cycles before it loses meaningful capacity. Confirm your model number (A2442, A2779, A2918, or A2992) so the replacement pack, in the 55 to 95 Wh range, matches your machine before you open it up.

Watch for quickly draining charge, the machine shutting down well before reaching 0 percent, or a cycle count approaching the rated 1,000 cycles. Other clues include the laptop running hot, the battery percentage jumping around, or the system reporting that service is recommended. Since these packs hold about 55 to 95 Wh when healthy, a noticeable drop in runtime is a strong indicator. Check your model number (such as A2779) so you can order the correct replacement, priced from $69.99 to $87.99.
