It depends on your model year. The Late 2010 and Mid 2011 A1370 uses the A1375 battery, while the Mid 2012 through Early 2015 A1465 uses the A1406 or A1495. These are lithium-ion packs running about 10.8 to 11.26 V, and across the category capacity falls in the roughly 55 to 95 Wh range. Because the two generations are not cross-compatible, you should confirm your model number (A1370 or A1465) and year before ordering from the 18 part numbers we carry.

Check the model number printed on the bottom case, usually A1370 or A1465, and note the year. The A1370 (Late 2010 / Mid 2011) takes the A1375, while the A1465 (Mid 2012 to Early 2015) takes the A1406 or A1495. With 18 distinct part numbers covering about 77 compatible models, matching both the model number and year is the most reliable way to land on the correct battery. Common part numbers in this category include 020-6380-A, 661-5229, and 020-5071-B.

Replacement batteries for the MacBook Air 11″ range from $34.99 to $63.99. The exact price depends on your model year, capacity, and the specific part number, since the A1370 and A1465 generations use different batteries. With 18 part numbers covering about 77 compatible models, matching your exact model (for example A1370 versus A1465) keeps you in the right price band and avoids ordering a battery that does not fit.

No, not across generations. The Late 2010 / Mid 2011 A1370 uses the A1375, while the Mid 2012 through Early 2015 A1465 uses the A1406 or A1495. Although the packs look similar, the connector placement changed between generations, so they will not drop in interchangeably. Some part numbers do overlap within a generation, such as the A1406 fitting certain A1370 and A1465 models, but you should always confirm your exact model number and year before buying.

The main difference is generation and connector placement. The A1370 (Late 2010 / Mid 2011) uses the A1375, while the A1465 (Mid 2012 to Early 2015) uses the A1406 or A1495 with a relocated connector, which is why they are not cross-compatible. Both generations are lithium-ion and held internally by five screws (three longer top screws and two shorter bottom screws). Voltage runs about 10.8 to 11.26 V across the category, so confirming your year matters more than the physical resemblance.

Look in two places. The model number (A1370 or A1465) is printed on the bottom case near the regulatory text, and the battery part number is usually printed directly on the battery itself once the bottom panel is removed. Common part numbers in this category include 020-6380-A, A1322557, 661-5229, and MA348LL/A. Matching the printed number against your model and year is the surest way to select the correct one from our 18 available part numbers.

Yes, with the right tools. On both the A1370 and A1465, the battery is held internally by five screws, three longer top screws and two shorter bottom screws, after the bottom panel comes off. You will need the correct drivers for the case and battery screws, and you should disconnect the battery connector carefully since its placement changed between the A1375 generation and the A1406 / A1495 generation. Confirm your model number and year first so you install the correct part.

Watch for sharply reduced runtime, the laptop shutting down before reaching 0 percent, or charge stalling well below full. On these 10.8 to 11.26 V lithium-ion packs, you may also notice the machine running mostly when plugged in or the charge percentage jumping around. If your A1370 or A1465 no longer holds a usable charge for daily web, word processing, and email tasks, a replacement in the $34.99 to $63.99 range matched to your exact model is the fix.
