MacBook Air 13" A1304 (Mid 2009) Battery Replacement

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.

  • Turnaround: Same day where possible, subject to stock and workload
  • 6-month warranty on the replacement battery
  • Walk-in near Liverpool Street Station or use our UK mail-in service

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.

Works great, do the double drain for best results
My 06 Altima (185k miles) had been burning massive amounts of oil (like 4 quarts every 800 miles) due to a leaking PCV valve hose that took forever for me to narrow down (months). So after getting that under control I figured I needed to decontaminate the poor engine. When using this I idled my car to operating temp (about 8 minutes). Poured the bottle in, idled it for another 15 minutes. Drained the oil (black and thick). Put the plug back in, poured about 2.5qts of new oil in. Idled it for 10 minutes. Drained that (black but much thinner). Took the old filter off. Let both areas drain for 10 minutes. Put the plug back in, put the new filter on and filled with the 4.6qts of new oil my car calls for. Ran for a few minutes (like 2 with a few revs) and then let sit for 10 mins before checking the level. When I checked my dipstick it was so clean I thought I had a leak because I couldn't see it on any of the crosshatch. I ended up having to go by touch to get the reading. This stuff is amazing.

Worked for me! Definitely recommend!
Used a whole can in my 2009 Civic 1.8L with 150k miles. I can honestly say, this helped remove a lot of sludge out of the engine. The oil came out with a water-like texture and super dark! Before taking out the oil filter, I added new lower cost oil to the engine and let the engine run for about 5 minutes to get that extra flush! You can definitely see all the extra sludge in the new oil! Drained and refilled with new oil and filter. The engine definitely sounded quieter and smoother than before! If you value your car, I would definitely recommend doing this flush on your higher mileage cars every 50k miles or so! Definitely recommend this LiquiMoly product!

3rd Update! See review... Good stuff and works as advertised...
Update - 3rd oil change/flush. Engine oil draining from engine is waaaay cleaner than my first flush. Probably won't need to do a 4th time for several changes. I added Ceratec at this change and am amazed how much better the engine performs since my initial flush. Less clatter and very smooth idle. (Jeep 4.0 I6) Update- 2nd change and used the flush again. About 7000 miles from first use. The oil was cleaner and less "gunky" as first time but oil was definitely dirtier than normal. Right away noticed off idle throttle response improved. Then on a drive I take regularly with a mountain pass and long downhill I noticed that even tho the jeep downshifted out of OD it took much less throttle to hold 65 up a long grade. On the downhill normally I would see 50-60 mpg max on the digital readout. This time. It went to 99 which to me indicates more vaccum below the throttle plate. My guess is the rings freed up a bit more than the first flush and highway mileage is up to 23+ where I would get 21 before. Nice! Used in 2001 Jeep Grand Cherokee. 140k miles and a ticking lifter (common in the 4.0 - 6 cylinder...). Definitely cleaned sludge (oil filter very heavy!) and oil was dark when draining. Idles smoother, oil stays cleaner longer, slight oil pressure increase and runs cooler. The lifter still ticks but probably a cam lobe issue. Will use it after 7500 miles or 1 year. Will report back after next change.
