Apple MacBook Air 13" (M2, 2022) battery capacity & backup time

Apple's spec page lists 52.6 Wh for the Apple MacBook Air 13" (M2, 2022) (built-in 52.6 Wh). The capacity of yours is printed on the battery label and shown as "design capacity" in a Windows battery report.

Estimated for a new 52.6 Wh pack at about 60% brightness: 12 h 30 min of browsing or office work, 7 h 10 min of video calls and 2 h 45 min of gaming. These are estimates from typical power draw, not measurements.

On a used battery at 80% health with the 52.6 Wh pack, office work runs for about 10 h, so a 2-hour outage is covered for the laptop itself. Your Wi-Fi router still needs a mini UPS; the load-shedding calculator works out both.

Replace it when the full-charge capacity falls to about 60-70% of the design capacity (around 34 Wh on a 52.6 Wh pack), when the laptop shuts down at 20-40%, or straight away if the battery swells and lifts the keyboard or bottom cover. Run powercfg /batteryreport in Windows to see both numbers.

Our model cost guide estimates Rs. 7,000 – 9,000 (tier-1 compatible pack), Rs. 9,500 – 11,500 (genuine / oem pack); the final price is confirmed after a free check. Every battery and fitting job carries our 30-day warranty. Pay cash at the shop, by bank transfer, JazzCash or Easypaisa.
