Macbook Pro Battery Bulge
If you notice a bulge in MacBook’s battery, this may be due to heavy usage or charging it overnight. In this case, you should unplug your MacBook from mains power, or move it somewhere cool, or shut down your Mac. You should copy your data onto an external hard drive or USB stick.
If the MacBook Pros battery bulges, burns, or explodes, bring it out, allow smoke and flames to extinguish, place in a fireproof container, and IMMEDIATELY SEE an Apple Genius for a replacement battery and additional assessment. You will need the battery replaced, as well as any damage to the MacBook repaired. Follow the steps outlined above for how to remove and replace your battery, and you can continue using your Mac securely for the long term.
Keep in mind that Apple wants to address any other issues that may exist with your laptop before replacing your battery, and additional repairs may not be free. For the most part, you can follow the devices battery replacement manual, but extra caution should be taken to prevent damaging your battery when removing it. It is important to note that you cannot repair a swollen or bad battery; you can only remove it.
Swollen batteries may also be caused by manufacturing defects or some other type of physical damage. It seems that battery expansion may be caused also by aging, manufacturer defects, and improperly cycling a battery over time (e.g. Damage caused on the outside of the device may be transferred to the battery, and result in it heating up and swelling.
Lithium-ion batteries may swell from a deep discharge in the cells; typically, Lithium-ion batteries are controlled by a circuitry, sometimes called the Battery Management System, or BMS, which keeps this from happening. In cold temperatures, lithium-ion batteries work well, but cannot be charged quickly without serious damage. For that reason, any device using Lithium-ion cells should incorporate circuitry capable of sensing such uncontrolled cycles and disconnecting the battery.
As lithium-ion batteries age, the chemical reactions that generate electricity are no longer completely completed, creating gases that can make a battery bulge. When the lithium-ion battery is overcharged, lithium builds up more quickly than it can deplete, thereby losing stability. Overcharging lithium batteries is a major cause of swelling and expansion.
Mechanical damage to the battery, such as hitting hard surfaces and dents in the case, may lead to swelling, as may exposure to too much heat. On the MacBook, you will typically notice a swelling battery pressing against the trackpad and surrounding lower case. With an iPhone or iPad, a swollen battery is generally noticeable as it starts warping the case, and may even break your screen–it all depends where the swelling is happening, and which parts of the device are giving way first.

Swelling is a sign that something is wrong with your MacBooks battery, and if you keep using it and charging it, it can lead to fire or an explosion. If you do not address swollen batteries on a MacBook immediately, it can lead to overheating of the MacBook, or even to fire. Ultimately, do not ignore it; eventually, your battery will no longer function normally, and once swelling starts, there is no turning back. If you begin to see signs of damage, swelling, or an exhausted battery (in the latter case, the damage will hold the charge for only a brief period), then change it now, rather than later.
When you find an over-inflated battery, unplug your device immediately and power off your power supply ASAP. Charge your battery as it gets lower, and then unplug when you are done charging. Leaving the battery at 100% charge or totally empty for an extended period can also reduce battery life, so if you are planning on keeping the device for several weeks or longer without using it, recharge/discharge to around 40% capacity and turn off before doing so. In either case, you will want to take action quickly to avoid the swelling of your battery damaging the rest of the parts in your Macbook Air.
A telephone or laptop battery is usually not charged or discharged fast enough for this to become a problem, fast charging and discharges may prematurely drain a battery and cause it to experience some discharge. Removing an over-swollen laptop battery may be dangerous as well, but keeping a laptop running on it, or otherwise leaving it inside the laptop, is not safe either. When the MacBook Pros battery starts looking like a blowfish when it starts expanding or swelling, it is time to either change your battery or call experts at CPR Cell Phone Repair to get help. An expanding or swelling MacBook Pros battery can begin with trackpad failures or an obvious bulge in your laptops body.

If the batteries inner layers are not maintaining the correct separation (due to damage or defects), it may leak, expand, or even burn.
Will Apple remove a swollen battery?
Battery swelling frequently occurs for a variety of illogical causes, including conceivably poor power management or a manufacturing accident. The main thing Apple won’t do is swap out a battery if there is a problem that prevents the device from being properly reassembled.
Is it safe to use a laptop with a swollen battery?
Disconnect the laptop from the AC adapter, let the battery drain, and stop using it to avoid further potential damage to the device enclosure or internal components that could cause malfunction. Batteries that are swollen should not be used and should be replaced as well as properly disposed of.
