USAbatteries.com stocks 1 compatible replacement batteries for the Apple MacBook series, covering 77+ laptop configurations and 18 distinct part numbers. Replacement batteries in this category are priced at $68.99.

The 15-inch MacBook Air is Apple’s larger-screen ultraportable, launched in June 2023 with the M2 chip and updated in March 2024 with the M3. It is built for students, business professionals, and casual users who want more screen room for multitasking without the weight or price of a Pro. The category spans about 77 compatible models across the 2023 and 2024 release years.

These models use lithium-ion batteries rated from 10.8 to 11.26 V with capacities of about 55 to 95 Wh, and a typical 15″ Air pack sits near 66.5 Wh. Part numbers vary by chip generation and year, so a 2023 M2 unit (Model Identifier A2941) and a 2024 M3 unit (Model Identifier A3114 or A3241) can take different batteries even though the chassis looks nearly identical. That is why matching your exact model is essential before ordering from the 18 distinct part numbers in this line.

Always confirm your exact model number and the part number printed on your current battery before ordering.

Frequently Asked Questions

What battery does the MacBook Air 15″ use?

The MacBook Air 15″ uses a lithium-ion battery rated between 10.8 and 11.26 V, with capacity in the 55 to 95 Wh range and a typical pack near 66.5 Wh. The exact part depends on your year and chip: 2023 M2 units carry Model Identifier A2941, while 2024 M3 units use A3114 or A3241. Common part numbers in this category include 020-6380-A and 661-5229. Check your Model Identifier first, then match it to the correct part number before ordering.

How do I find the right battery for my MacBook Air 15″ model?

Find your Model Identifier (such as A2941 for 2023 or A3114 for 2024) printed on the underside of the laptop, then match it to the listed part number. Because this line covers about 77 models across 18 distinct part numbers, the identifier is the most reliable way to confirm a fit. You can also check About This Mac under the Apple menu for model details. Once you have the identifier, compare it against options like 020-5071-B or A1322557 to confirm compatibility.

How much does a MacBook Air 15″ replacement battery cost?

A MacBook Air 15″ replacement battery costs $68.99 in this category. Pricing is consistent across the listed part numbers, so a 2023 M2 pack (A2941) and a 2024 M3 pack (A3114 or A3241) fall at the same price point. Confirm your Model Identifier before checkout so you order the correct part the first time.

Are MacBook Air 15″ batteries interchangeable?

Not always. While the M2 (2023) and M3 (2024) models share a similar chassis, they use different Model Identifiers (A2941 versus A3114 or A3241) and can require different part numbers. With 18 distinct parts covering this line, you should never assume a battery from one year fits another. Match your exact Model Identifier to the correct part number, such as 020-6380-A, before buying.

What differs between the MacBook Air 15″ sub-series batteries?

The main difference is chip generation and year. The M2 (2023) sub-series uses Model Identifier A2941, while the M3 (2024) sub-series uses A3114 or A3241. Capacity stays similar at around 66.5 Wh, but the part numbers differ, so the right pack depends on which year you own. Both are internal, adhesive-mounted batteries within the 10.8 to 11.26 V range, and both install the same way with an adhesive kit.

Where do I find the battery part number?

Look at the underside of the laptop for the Model Identifier (for example A2941 or A3114), then use it to find the matching battery part number like 661-5229 or 020-5071-B. You can also open About This Mac from the Apple menu to confirm your model details. With about 77 compatible models in this line, the identifier is the key to selecting from the correct part numbers such as MA348LL/A or MC-MBOOK15.

Can I replace the MacBook Air 15″ battery myself?

Yes, but it takes care because the battery is glued to the chassis. Both the M2 (2023, A2941) and M3 (2024, A3114 or A3241) models use adhesive-mounted packs, so a successful swap usually needs an adhesive remover and fresh adhesive strips, often included in replacement kits. Work slowly, keep your tools organized, and confirm your Model Identifier matches the part number (such as 020-6380-A) before starting.

What are the signs the battery needs replacing?

Watch for a “Service Recommended” battery warning, rapid charge loss, shutdowns at moderate charge levels, or a unit that will not power on without being plugged in. Apple batteries are generally rated for about 1,000 charge cycles before service is recommended, so a high cycle count is another sign. If you see these symptoms on your A2941 or A3114 model, a replacement battery at $68.99 will restore normal runtime.
