What Causes A Cell Phone Battery To Swell Up. When the gas produced by a malfunction does not find where to escape deforms the battery itself causing the swelling. Bulging batteries mean only one thing- buildup of gas inside.
For instance if you used 24V charger to charge a 12V battery it will most probably result in overcharging of the battery. Lithium-ion Polymer batteries have become popular across the industry in recent years due to their slim and customizable form factor and longer battery useful life. Here are some usage habits that tend to cause battery swelling due to a combination of internal charging mechanisms and exposure to prolonged heat.
Under those circumstances the chemical reaction that keeps your battery running breaks down and just like the name suggests outputs gas.
Battery swelling happens due to a little thing called outgassing which occurs when a battery gets overcharged damaged or simply old. Overcharge conditions which accelerate parasitic reactions between the electrodes and electrolyte with release of heat. They are the result of too much current inside a cell of the battery which causes a build-up of heat and gas. Leaving a hotspot constantly plugged into.
