Measuring MacBook battery life in straight hours of real-world utilization (as Apple likes to do) is just not all the time an correct metric for comparability functions as so many use and environmental components play an element. We will, nonetheless, depend on straight technical specs to inform us the acknowledged battery capacities of every MacBook.
The place Apple is secretive about iPhone battery specs (see our record of iPhone battery capacities based mostly on teardowns), the corporate does record MacBook capacities in Watt hours (Wh). We’ve trawled via the Apple product Tech Specs pages from 2009 to 2025 to carry you as full a listing as we are able to collect utilizing official Apple battery declarations.
The watt-hour is a unit of power equal to at least one watt (1W) of energy utilized for one hour of time. it’s calculated by multiplying the variety of Amps with the battery voltage. The upper the variety of Wh the longer a battery will final utilizing the identical software. Batteries will lose effectivity over time so don’t count on a 2009-era MacBook battery to nonetheless possess the identical energy because it did when it was new or greater than a 2025 mannequin, even when it had an initially larger Wh score.
