MacBook battery capacity: Apple silicon models in Wh

Read the capacity and charger columns separately

Battery capacity in watt-hours describes stored energy. Adapter wattage describes a power rating. A 100 Wh battery and a 140 W adapter are compatible numbers with different jobs: the adapter rating is neither the battery size nor constant electricity consumption. For a replacement charger, use the charger selection guide, which owns the cable and fast-charging details.

Find your chip and size under Apple menu › About This Mac, then match the row. The 13-inch Pro with M2 uses a plain M2 chip, not an M2 Pro processor. The 14-inch base M3 and M3 Pro/Max also need separate rows. Memory and SSD options are not repeated when Apple lists the same battery.

There are 26 rows in this compilation: nine Air rows, sixteen Pro rows and one Neo. Pro and Max chips share a row only where the cited specs give the same battery capacity; adapter differences stay visible. This counts specification families, not individual retail configurations or machines sold.

MacBook Air battery capacity by generation

The 13-inch M5 Air has 7.8% more headline battery capacity than the M1 Air: (53.8 ÷ 49.9 − 1) × 100 = 7.82%. That is a capacity comparison, not a measured improvement in runtime. Chip efficiency, screen brightness and the work being done still affect how long a charge lasts.

Within M5, the 15-inch Air stores 23.6% more energy than the 13-inch: (66.5 ÷ 53.8 − 1) × 100 = 23.61%. Its larger display also needs power. You cannot turn this percentage into extra hours without knowing the average draw of each computer. Our Air battery-life guide explains Apple's separate runtime figures.

MacBook Pro battery capacity and adapter figures

Two source differences are kept visible. Apple's November 2023 14-inch M3 Pro/Max page says 72.4 Wh in its main list but 69.6 Wh in a shared testing footnote. We have not silently selected a replacement figure. Also, the live commercial specs showed a 14-inch M6 on 30 October, while Apple's model-identification catalogue still ended at M5. Its row therefore cites the commercial page, which lists a 70 W adapter in the US box, 60 W as the recommended minimum, and fast charging with a 96 W adapter. What comes in the box can differ by country.

For the 16-inch Pro, Apple's 100 Wh headline is accompanied by an actual rating of 99.6 Wh. Both belong in a useful reference. A small rounding difference should not be confused with battery wear; a health reading from your own Mac answers a different question.

MacBook Neo battery capacity

The Neo is part of this Apple silicon reference because it uses A18 Pro, even though its chip name does not begin with M. Its smaller battery must not be treated as a damaged Air battery. For its own runtime and charging limits, see Neo battery life.

Original capacity, current capacity and charge level

The table records what Apple specifies for a new model. It does not read your battery. “Maximum Capacity” in macOS describes retained capacity relative to new, whereas the percentage next to the battery icon describes how full it is now. A full battery can have less usable energy than when it was new.

A dimensional example helps: if a hypothetical 53.8 Wh battery retained 90% of that energy, the arithmetic would be 53.8 × 0.90 = 48.42 Wh. That is an illustrative estimate, not a conversion promised by macOS's health percentage. Gauges, reserve capacity and software reporting can prevent an exact match. Use the condition and runtime together; see checking battery health.

Likewise, milliamp-hours cannot be compared across packs without voltage: Wh = mAh × V ÷ 1,000. Two packs with different voltages can store different energy at the same mAh value. For model comparisons, Apple's Wh figure avoids that missing input.

What this compilation can and cannot tell you

We transcribed Apple's model-specific Battery and Power sections, kept different actual-rating footnotes, and grouped only equal-capacity configurations. The cited adapter is the one listed when checked; Apple can revise its support pages, and what's in the box can vary by country. Fast-charge upgrades are intentionally left to the charger guide. All source rows were checked on 30 October 2026.

No runtime, recharge-time or efficiency test was run. The two percentage comparisons divide capacities only. Battery replacement parts, aftermarket packs, refurbished batteries and regional bundle changes are outside this dataset. A changed source should produce a dated correction, not a retroactive claim that a different adapter always shipped.

Capacity can also supply one input for a cost estimate. The charging-cost tables use explicit charging-loss assumptions and official electricity prices. For the power your work actually uses, read MacBook watts; do not multiply the adapter label by all the hours it is plugged in.

How Tend helps

Tend helps you look after your Mac; its optional companion shows how it's doing. Health, cycles, capacity and per-app estimated watts are Free; Pro adds a daily battery health record. It helps connect a short-lived charge to the apps doing the work, but it cannot measure your wall socket's charging losses or restore worn cells. See Free and Pro.
