Why Is Your Battery Swollen?

Using your phone while charging, charging it with low voltage power supply, charging it using generator, over charging it….are among the things we usually don’t take as serious issue regarding the health of our device batteries.

Common causes of battery swelling include:

1. Overcharge conditions which accelerate parasitic reactions between the electrodes and electrolyte, with release of heat and gases.
2. Poor cell quality and design with low anode to cathode stoichiometric ratios, particulate contamination
3. Mechanical damage to electrodes induced either during cell assembly or from the product application
4. Excessive temperatures (Do not leave your cell phone inside your car)
5. Deep discharge of cells

Anything that increases the self-discharge rate of a battery is bad (including poor manufacturing quality,  and exposure to heat) and allows your battery to go into deep discharge quicker.
