This lithium-ion battery replaces part numbers A1496, 020-8143-A and 020-8142-A in MacBook Air 13.3" models A1466 from 2013 through 2015. It supplies 7.6V and 54.4Wh capacity in a black housing. The unit is brand new and carries a 12-month warranty.

Normal thermal and power behaviour

Lithium-ion chemistry delivers steady voltage with minimal heat during typical workloads. No fan or active cooling is required inside the battery pack. Power draw matches the original specification so the MacBook manages charging and discharging normally.

Included component

The package contains one battery only. No tools, adhesive strips or installation guides are supplied. Buyers who need screwdrivers, spudgers or replacement screws must source them separately.

Questions about this item

How do I install the A1496 battery in my MacBook Air 13.3" A1466, and what step do people often miss?

Remove the bottom case screws, disconnect the old battery connector before lifting it out, then connect the new 7.6V 54.4Wh pack and secure it; the step often missed is disconnecting the battery cable first to avoid a short.

What maintenance or replacement will the 7.6V 54.4Wh lithium-ion battery need over time?

The lithium-ion cells lose capacity with each charge cycle; when run time drops below your needs, replace the A1496 pack — no other maintenance is required.

What limit appears first during sustained use of this 54.4Wh replacement battery?

The 54.4Wh capacity sets the runtime ceiling; under heavy load the pack will deplete faster and voltage sag may trigger system sleep before the 7.6V nominal level is reached.
