Apple MacBook Pro 13" (2017, Two Thunderbolt 3 ports) battery capacity & backup time

Apple's spec page lists 54.5 Wh for the Apple MacBook Pro 13" (2017, Two Thunderbolt 3 ports) (built-in 54.5 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 54.5 Wh pack at about 60% brightness: 6 h 30 min of browsing or office work, 4 h 20 min of video calls and 1 h 35 min of gaming. These are estimates from typical power draw, not measurements.

On a used battery at 80% health with the 54.5 Wh pack, office work runs for about 5 h 10 min, 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 35 Wh on a 54.5 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 – 9,500 (tier-1 compatible pack), Rs. 10,000 – 12,000 (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.
