- Visible Damage: Cracks, swelling, or bulging in the battery case are serious red flags. These physical deformities can compromise the battery’s functionality and safety.
- Leaks and Corrosion: Any signs of leakage or corrosion around the battery terminals or casing indicate potential chemical imbalances due to overcharging or physical damage. Leaks can be identified by wet spots or discoloration near the battery.
- Swollen Cases: Swelling often results from overcharging, causing internal gases to pressurize the battery housing. This can lead to a distorted or ruptured case, which is dangerous and degrades performance.
- Abnormal Noises or Smells: Unusual sounds or odors, such as sulfur smells, are indicative of internal chemical issues that can lead to battery failure.
- Discoloration or Bumps: Bumps or discoloration on the battery surface can be signs of degradation and should be inspected closely for possible internal damage.
