Whenever the battery gets damaged by some means, it may release highly toxic and flammable gases. To prevent these gases from leaking and causing serious health and fire hazards, the manufacturers wrap the battery without any vents. As a result, the gases get trapped inside and expand to increase the battery volume. And, you will find the battery swelling. The battery may burst and cause damage if it swells too much. Hence, you should immediately bring your concern to resolve the issue. In this guide, we will discuss the possible ways to fix the swelling laptop battery.
Symptoms of a Swollen Battery
Causes of a Swollen Battery
The lithium-ion battery is made up of a few cells separated by electrolytes. When the battery temperature crosses the threshold, the electrolyte starts decomposing excessively due to the accelerated chemical reaction.
Difficult to click the keyboard buttons and trackpad. Keyboard or touchpad extruding outwards. Out-of-shape back panel. Deformed laptop shape. Fast Battery Drainage. Puffed battery.
As a result, it produces gas which gets trapped inside the battery. The battery starts swelling as the gas accumulates and causes risks for hazards. There are several causes for the electrolyte to degrade, resulting in a swollen battery. Let’s see a few of them.
