Compatible models: A1304, EMC 2334

The MacBook Air 13-inch A1304 is one of the original ultra-thin MacBook Air designs, built with a 40Wh battery and a Core 2 Duo processor. At over fifteen years old, the original battery in any A1304 is essentially certain to need replacement. These machines remain surprisingly capable for light document work, web browsing and email. A new battery is what gives them the ability to function away from the mains again.

Signs your MacBook Air 13" A1304 battery may need replacing

At this age, the original A1304 battery has gone through far more charge cycles than Apple designed it for. Capacity is typically well below 50 per cent of the original 40Wh, and in many cases the machine will only run reliably when plugged in.

• Battery draining significantly faster than it used to
• Device shutting down unexpectedly, particularly at lower charge percentages
• Only running reliably when connected to power throughout the day
• Battery percentage dropping suddenly or behaving inconsistently
• MacBook running warmer than usual during normal tasks
• Screen lifting slightly from the chassis (can indicate a swollen battery, book as soon as possible)
• Battery not detected at all by the operating system, showing a missing icon in the menu bar
• Go to Apple Menu > About This Mac > System Information > Power, then check Cycle Count and Condition

What is included

• Safe removal of the bottom case and existing battery
• Fitting of a quality replacement 40Wh battery cell
• Post-repair charging and power stability checks
• Full function test covering power, MagSafe charging, keyboard, trackpad and display
• 6-month warranty on the replacement battery

How to confirm your model

Go to Apple Menu > About This Mac > System Report > Hardware Overview to check your model identifier.

This repair covers: A1304, EMC 2334.

The model number is also printed on the underside of the machine near the hinge. If you are unsure, bring the MacBook in and we will confirm the model before starting any work.

The A1304 uses a MagSafe 1 connector. This is the original MagSafe design with a slightly different shape from MagSafe 2. The model identifier A1304 is on the underside of the machine and in Apple Menu > About This Mac.
