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.

Sadly, lithium-ion chemistry isn’t good—all batteries are consumables, which implies they get outdated.
