How to Tell When a Cell Phone Battery Has Water Damage
- 1). Remove the battery cover from the back of the cell phone, and then remove the battery from the device.
- 2). Look along the edges of the battery for a small white, pink or red sticker. On some batteries, this will be on the outside of the battery case, while on others, it may be behind a shield of clear plastic. If the sticker has any pink or red in it, the battery has come into contact with enough moisture to set off this indicator and has water damage.
- 3). Observe the metal contacts on one side of the battery. Water damage will cause corrosion, which is a breaking down of the metal components. This will appear as a green or white growth on the battery's contacts.
- 4). Look at the metal contacts on the phone itself, where your battery comes into contact with your phone. If these are corroded, it is a good sign that your battery has water damage, even if the corrosion doesn't appear on the battery contacts.
- 5). Observe the battery recess on your cell phone. Many phones have an additional moisture indicator on the inside of the recess. If this is pink or red, it is also a strong sign that the battery has water damage, even if there are no signs on the battery itself.
