What can cause battery to swell?
Battery swelling is the process of a battery increasing in size due to several possible causes. These cause can range from exposure to high temperatures, age of the battery, exposure to extreme charging current, or a fault in the battery itself.
Exposure to high temperatures- batteries such as those in smartphones, tablets, and laptops are built to withstand certain amounts of heat. However, when exposed to extremely high temperatures, the battery can begin to swell up due to the pressure of the expanding materials inside the battery.
This swelling can cause the battery to increase in size and become deformed.
Age of the battery- as batteries age, they can become less efficient in storing and releasing energy, leading to the battery cells to become weaker and swell up. This is typically seen in older batteries that are no longer kept at their optimal performance.
Exposure to extreme charging current- when a battery is charged with an extremely high current, the molecules in the battery cells can become strained, causing the cell walls to become weakened. This can also lead to the battery swelling up.
Fault in the battery itself- in some cases, a manufacturing defect can lead to batteries swelling up. This happens when the cells within the battery become unbalanced, or when there is a short circuit within the battery.
This type of damage can cause the battery to swell up due to rupturing of the cells within the battery.
How do you deflate a bloated battery?

What causes battery expansion?
Battery expansion is caused when the battery has been charged or discharged beyond its limits, typically due to excessive amounts of electrical current. This can cause the materials in the battery, such as the electrolyte, to expand as a result of the heat and pressure that is generated during the charging and discharging process.
This expansion can cause the casing of the battery to become deformed, cracked, or otherwise damaged. In extreme cases, the internal parts of the battery can become exposed, creating a potential fire hazard.
Mishandling of the battery, particularly in cases when the terminals are short-circuited, can also cause expansion. Additionally, recharging batteries that are old or not designed for the current-draw of the device can cause them to expand as well.
How do I stop my battery from expanding?
Stopping your battery from expanding requires taking proactive steps to reduce the amount of charge it holds and prevent overcharging. Here are some steps you can take to help stop your battery from expanding:
1. Use the appropriate charger for your device. Different types of batteries require different types of chargers. Make sure that you are using the correct charger for your device.
2. Unplug your device after it is fully charged. Doing this will help reduce the amount of charge the battery holds and prevent it from overcharging.
3. Avoid placing your device in extreme temperatures. Excessively hot or cold temperatures can cause the battery to expand due to thermal expansion and contraction.
4. Keep the battery clean. Charging ports and battery contacts should be kept clean and free of debris as this can lead to an increase in charge and cause the battery to expand.
5. Replace your old battery. Over time, batteries can become worn and can expand as a result. Replacing your battery every few years is a good idea to help reduce the risk of it expanding.
Can a swollen battery explode if not plugged in?
No, a swollen battery cannot explode if not plugged in, as swelling occurs due to a buildup of pressure from a chemical reaction that occurs when the battery is used or charged. When a battery is not plugged in and not used, there is no chemical reaction taking place and therefore no build up of pressure leading to swelling.
Although exploding due to a swollen battery is unlikely, it is not impossible as some types of lithium-ion batteries have been known to short-circuit and catch fire or explode due to a buildup of charged particles inside the cells.
It is important to take note of any swelling in a battery and to immediately stop using it and replace it with a new one as soon as possible.
Are bulging batteries a fire hazard?
Yes, bulging batteries can be a fire hazard. When batteries overheat or become damaged, they can let off combustible gases and heat, which can be a major risk for starting a fire. This is especially likely to happen when batteries are overcharged or have sustained physical damage, such as being punctured or crushed.
The hazard is highest with lithium ion batteries, since they contain flammable electrolytes. To minimize the risk of a fire, it is important to use the right type and size of battery for the device it is powering, as it will ensure proper voltage and current.
It is also important not to leave charging batteries unattended or overcharge them, as they can heat up quickly and cause a fire under these circumstances. Additionally, any damaged batteries should be disposed of immediately in a safe manner.
Can you fix an expanded battery?
Unfortunately, it is not usually possible to fix an expanded battery. If the battery has become physically distorted or expanded due to overcharging, extended usage or age, it cannot be corrected, and it is likely that the battery will need to be replaced.
