Battery swelling occurs because of slightly factor known as outgassing, which happens when a battery will get overcharged, broken, or just outdated. Below these circumstances, the chemical response that retains your battery working breaks down and, similar to the identify suggests, outputs fuel. The battery casing is constructed to comprise that nasty fuel—so, inevitably, it bloats up.

In case your bravery has prevailed, and also you need to do the substitute your self—proper on! Right here are some things it’s best to do earlier than the restore to make sure your security: Be sure your battery’s cost is as little as attainable by letting it drain to close zero p.c—this enormously reduces the danger of a hearth. Additionally, be sure you maximize the air flow within the space the place you’re doing the restore, to cut back publicity to these aforementioned fumes. And, your chemistry instructor remains to be proper—put on eye safety (ideally full security goggles).

Wherever you restore, and regardless of the temptation, don’t expose the battery to water or moisture—the lithium within the battery can react with the water and trigger extra issues than you began with.
I’m going to reiterate that to verify it actually sinks in: DO NOT expose the battery to water or moisture—as a result of the lithium will react with the water, probably inflicting a fireplace.
Okay, now you may lastly begin to take away the battery. For probably the most half, you may simply observe the restore information on your specific device. We additionally suggest utilizing a ‘lil solvent like iFixit’s adhesive remover, high-concentration isopropyl alcohol, or acetone. The solvent will cut back the necessity to pry in opposition to or flex the battery. However—and it is a massive however—solvents are flammable, so use them as sparingly as attainable, and acetone might trigger injury to plastic components. Solely use uninteresting, plastic instruments to keep away from puncturing the battery—punctures can release its toxic contents or start a flaming reaction.

Sadly, lithium-ion chemistry isn’t good—all batteries are consumables, which implies they get outdated. And like us, when batteries get outdated, the processes that hold them working begin to degrade. However the place we get wrinkles and breathe out CO2, batteries produce poisonous gases and bloat themselves as much as comprise it—till they explode.
