Causes of Battery Swelling

There are several factors that can cause a battery to swell:

  • Overcharging: This is one of the main causes of swollen batteries. Overcharging occurs when the battery is continuously charged at a higher voltage than recommended, leading to the production of excess gas and subsequent swelling. To avoid overcharging, you should only charge your device when the battery is low. You should also unplug your device once it is fully charged. If you leave your device plugged in after it is fully charged, it can damage the battery.
  • Exposure to High Temperatures: When a battery is subjected to extreme heat, the chemical reactions inside it become more active. This increased activity generates additional gas, causing the battery to expand. In hot climates or during the summer months, the temperature under the hood of a car can rise significantly. If the battery is not adequately insulated or shielded from this heat, it can lead to swelling. Additionally, leaving a car parked in direct sunlight for extended periods can also expose the battery to excessive heat.
  • Physical Damage: Any physical damage to the battery can cause it to swell. This can be due to mishandling, dropping the device, or impact from an accident. Physical damage can cause internal components to break down, leading to the release of gas and swelling.
  • Age and Usage: As batteries age, their internal components deteriorate, leading to the release of gas and swelling. Additionally, the usage pattern of the battery can also contribute to swelling. For example, if a battery is constantly charged to 100% and discharged to 0%, it can cause the battery to swell.
  • Manufacturing Defects: Sometimes, the swelling can be due to manufacturing defects. The manufacturer may have used substandard materials or components, or the battery may have been produced under poor conditions that led to the release of gas and swelling.

Understanding these causes can help you take steps to prevent battery swelling, handle it safely if it occurs, and maintain the performance and longevity of your device.
