Replacement Battery for 11-inch MacBook Air

This new lithium-ion polymer battery replaces part number A1406 in MacBook Air 11-inch models A1370 and A1465 from 2011 through 2014. It restores portable power for owners whose original cells no longer hold a useful charge. The pack is not compatible with 13-inch or Retina MacBook Air models.

Thermals and Power Behaviour

Rated at 7.4 volts and 4680 milliampere-hours for 35 watt-hours, the cell chemistry matches the factory specification. Built-in circuit protection guards against over-charge, over-discharge and short circuits during normal operation. No active cooling is required and the battery adds no audible noise.

Included Tools for Installation

The package supplies four screwdrivers sized for the pentalobe and tri-wing fasteners used on the 11-inch chassis. These tools let you open the case, swap the battery and reassemble the MacBook without sourcing a separate kit. No software, drivers or calibration utilities are bundled.

Questions about this item

How do I install the A1406 battery in my MacBook Air 11-inch A1465, and which step often goes wrong?

Remove the bottom case screws with the included screwdrivers, disconnect the old battery connector, fit the new 7.4V 4680mAh pack, reconnect it, then replace the case; the step most often missed is reconnecting the battery data cable before screwing the case shut.

What maintenance will the A1406 Li-ion polymer battery need later?

No scheduled maintenance is required; keep the laptop cool, avoid leaving it at 100% or 0% for weeks, and run a full charge cycle once a month if the machine stays plugged in.

What limit appears first during sustained use of this 35Wh battery?

The 35 watt-hour capacity sets the runtime ceiling; under continuous load the pack will deplete in a few hours, and its built-in protection circuit will cut output if voltage drops too low.
