Your cell phone battery swelled and you don't know how to deal with the problem? With a little care, you will be able to get rid of the defective part safely and without major difficulties. Remove the battery and take it to a disposal center or service center for safe disposal. It is important to take care when handling the battery as it can be dangerous.
Steps
Method 1 of 3: Disposing of the Battery

Step 1. Do not throw the battery in the trash
A lithium battery is considered hazardous waste and should not be disposed of with normal waste. A swollen part is still a hazardous waste, in addition to posing risks for professionals who handle the city's garbage.

Step 2. Take the battery to an electronics disposal center
Do some research to find a center near you and take the part to be safely disposed of.
If you cannot find a center on the internet, contact the city hall to find out more

Step 3. Seek technical assistance
If you cannot find a disposal center, seek technical assistance, as professionals are likely to be able to safely dispose of this equipment.
Method 2 of 3: Removing a Swollen Battery

Step 1. Remove the battery if possible
If the part is removable, remove it carefully. Handle it slowly so you don't pierce it, or you will create more risks to your safety.
If possible, wear protective gloves and eyewear during the procedure

Step 2. Look for a professional if you cannot easily remove the battery
Stop what you are doing and take the device to a specialized technical assistance so that a professional can remove the battery for you. Forcing a stuck battery can puncture it and cause an explosion or fire hazard.
If the battery is not removable or you are unsure of the proper procedure, seek technical assistance

Step 3. Place the battery in a cool container
Once removed, store it in a cool container with a lid to protect it from transport to the appropriate disposal center.
Method 3 of 3: Taking Proper Precautions

Step 1. See a professional if you believe the battery has been punctured
If you punctured the battery while trying to remove it or noticed a discharge that could indicate a rupture, see a professional immediately. Go to a service center for someone who understands the matter to deal with the problem, as the battery could explode or cause a fire.

Step 2. Do not attempt to charge a bloated battery
If you notice swelling, disconnect the device from power and remove the battery immediately. If you keep charging it, you could end up triggering an explosion.

Step 3. Do not recycle bloated batteries
In many metropolitan areas, there are recycling centers that accept old electronics. As good as that is, bloated batteries cannot be safely reused.

Step 4. Take care when handling a swollen battery
Never bring sharp objects close to it, as you run the risk of piercing it. Never try to force it either; if you are unsure how to safely remove it from the device, see a professional.
